    Water treatment plant
    The invention relates to a device for treating a liquid with at least one supply line, at least one filter unit, at least one discharge line and a central control unit.
    Devices for the treatment of liquids, in particular water treatment plants for the production of drinking water or service water are known from the prior art. DE 38 28 026 A1, for example, shows a device for hygienic treatment of liquids, especially drinking water, with a supply line, a filter unit, and a derivative. The apparatus further comprises a source of UV radiation in a tubular body of UV-transmitting material extending through one or more portions of the apparatus disposed one behind the other in the flow direction of the water through which the water to be treated flows and which are separated by activated carbon filters. The water to be treated is therefore exposed before entering the activated carbon filter each a germicidal UV radiation, which eliminates the risk of excessive germ growth in the field of activated carbon filter.
    DE 4 008 458 A1 shows a method and a device for the treatment of water in a tapping point system. The construction relates to a method and a device in which pre-purified pipe water in a filter section is fed to a reverse osmosis module while building up a transmembrane pressure difference. The permeate stream emerging at the permeate outlet is conducted via a UV sterilization path into a pressureless storage tank.
    From there, the pure water can be removed with the help of a feed pump at the tap. * * · «« «B *« · 2

    Furthermore, DE 10 2005 007 395 A1 discloses a mobile water treatment system which has a central control unit. Furthermore, water treatment plants for the treatment of water for agriculture, snowmaking systems, mining, disaster relief, drinking water supplies in the municipal sector, as well as isolated solutions for drinking water supplies, especially in remote areas, known.
    Depending on the degree of pollution, type of pollution, desired throughput, etc., different methods and systems for water treatment are used. For example, until now large plants were required for the municipal drinking water supply in order to achieve the required throughput. Such systems are usually arranged stationary due to their size.
    However, new developments in the field of filter technology have made it possible to achieve higher throughputs in small water treatment plants. This favors the possibility of mobile water treatment plants e.g. Provide disaster relief, but with a throughput that is usually handled only stationary water treatment plants.
    The state of the art systems are usually specialized in a few applications. For example, there are water treatment systems for agriculture, for snow-making systems, for drinking water, for disaster relief, etc. Due to the different configuration of the different systems, the quantities of each individual system are very low. Mostly water treatment plants are custom-made, which are specialized in the respective field of application. 3

    Due to these customizations, the cost of such treatment plants are very high. The control units are usually set up in a decentralized manner, that is to say that a separate control is set up for each module and the coordination of the components takes place anew at each new installation.
    Objects of the present invention are to overcome the drawbacks of the prior art constructions, to provide a modular water treatment plant, which has compact dimensions and thereby can be used both stationary and mobile, which can be used for a variety of different applications, the central A control unit that is easy to commission, designed for a wide range of flow rates, with safety features designed to prevent contamination of drinking water, improve plant operation and assure component protection, and that are produced in high volumes through flexible use can and therefore brings cost advantages.
    The objects of the invention are achieved in that the filter unit comprises a controllable by the control unit, connectable to a backwash backwash filter. The use of a backwash filter, which can be backwashed during operation and especially automatically, allows for the first time the realization of a modular water treatment plant, which has compact dimensions and can be operated virtually continuously over a long time, Thus, such a system for the first time not only for emergency operation, but also for longer use and even the regular operation of water treatment can be used. Accordingly, numerous economic advantages open up by the inventive design of the water treatment plant.
    The backwash filter according to the invention can be any desired backwashable water filter. Essential for the invention is the
    I

    Property to be backwashed during operation by the accumulated impurities - the so-called filter cake - are removed from the filter material by diverting the liquid flow and thus the filter material is cleaned. A regular change of the filter material, which is inevitably accompanied by a stop of the treatment plant, is therefore no longer necessary.
    In particular, the backwash filter according to the invention may comprise a jacket-shaped filter body which is rotatable relative to the filter housing, wherein the filter body is always cleaned during the backwashing only over a partial area, as described for example in AT 504 361 B1. Such backflushing filters require a very small flushing volume and work even with a slight difference in pressure between flushing agent feed and flushing agent flush.
    According to the invention, provision may be made for a pre-filter pressure sensor in the flow direction in front of the filter unit and a post-filter pressure sensor in the flow direction downstream of the filter unit, which can be connectable to the control unit for assessing the degree of soiling of the backwash filter. This allows the controller to automatically judge if the filter is dirty and to request or initiate a backwash.
    Furthermore, it is provided that the filter unit can comprise an electric motor which can be activated by the control unit for carrying out the backwashing process. For carrying out the backwashing process, when using the backflushing process according to the invention, it must be set in rotation, which can be done automatically by the electric motor.
    To carry out the backwashing process, it can be provided according to the invention that the filter unit is a backwashing process which can be controlled by the control unit and is connected or connectable to a backwash line

This can preferably be designed as a UV reactor. In particular, it can be provided that the radiation source is a plant for producing ultraviolet radiation with low-pressure mercury radiators in accordance with ÖNORM M 5873-1 D.
    For measuring the degree of contamination, the radiation source may comprise at least one photosensor connectable or connected to the control unit. From the electrical measurement data of the photosensor, the control unit can draw conclusions about the purity of the water or the liquid to be treated.
    Furthermore, it is provided according to the invention that in the flow direction downstream of the filter unit, at least one seed port for introducing chemical substances can be attached. This may be in particular chlorine, but also other chemicals such as chlorine dioxide or silver ions, which are required for the treatment of the liquid. For the purpose of mixing the chemicals introduced, it may be provided that a static mixer is located in the flow direction downstream of the inoculation connection.
    An essential safety problem with a treatment plant according to the invention is that any polluted or contaminated water may never reach the discharge (the pure water outlet). This is particularly problematic in the event of a power failure.
    For this purpose, the invention provides that a provided with a normally open safety valve fault line can be provided, and the derivative can be provided with a normally closed safety valve. 6

In order to assess the quality of the treatment plant, it can further be provided according to the invention that the device comprises further sensors measuring the pressure, the flow and / or the temperature. However, other physical parameters can also be recorded by corresponding sensors. According to the invention, the sensors used can be connectable to the control unit in order to ensure that the measured values can be stored, processed, sent, etc.
    In the flow direction downstream of the filter unit, it is also possible to provide a bladder accumulator which can be connected to the control unit and serves as an expansion vessel. To regulate the operating pressure of the system may further be provided in the flow direction in front of the filter unit controllable by the control unit control valve. Such an inventive control valve may have an automatic venting, whereby the automatic commissioning of the system is significantly simplified. For this purpose, the control valve may have an integrated ventilation function. This can be achieved that the air in the filling of the valve (or even air bubbles which reach the control valve in operation) can escape into the atmosphere. As a result, the complex manual venting is superfluous and it is fully automatically ensured that the control valve can work properly.
    For further automation of the system, it is further provided according to the invention that an input pressure sensor which can be connected to the control unit can be provided in the flow direction upstream of the filter unit. This can supply the input pressure as a measured value to the control unit. Furthermore, in the flow direction upstream of the filter unit, a slider controllable by the control unit can be provided, as well as in FIG

    A major problem of conventional treatment plants is that the supply networks are often damaged by overaging, during construction and by pressure surges during operation or even by environmental influences (earthquakes, corrosion by soil chemistry, etc.) affected. The water treatment plant must treat the water with a lot of energy (power consumption) and / or use of chemicals and make it available under pressure. This expensive water then seeps through the leaks in the supply networks unused in the ground.
    For this reason, it may be provided in step a) that pressure and flow are automatically lowered by the control valve whenever no water is needed. This reduces the leakage and at the same time increases the service life of the supply network. It can be assumed that a given consumption plan (certain daily programs or weekly programs). In particular, it is provided that these programs can be activated, changed or changed by SMS command. ι I I I I I I I I I I

    A daily program can be subdivided in particular into several daily sections. In each section of the day, the control modes (pressure, flow), the considered sensor values (operating pressure, pre-filter pressure, post-filter pressure, flow), and the target values can be defined.
    Rule management processes the defined daily sections and moves to the prescribed rules
    This allows leakage losses in the supply network to be reduced at certain times. (Example: At night, where water consumption is almost zero.)
    According to the invention, it is further provided that the consumption is recorded and the program can control itself within a predetermined framework (artificial intelligence) in order to further reduce the leakage losses. In addition, in a method according to the invention, exceeding or falling below tail values and limits of pressure, temperature, flow rate, rinsing cycles, UV irradiations, and other quantities can be detected and displayed to the user by SMS or at a user interface of the control unit.

    Fig. 1 shows the schematic representation of a first embodiment of the device 1 according to the invention, which in this case as
    Water treatment plant is running. The device 1 has a supply line 2 for the water to be purified, a filter unit 3, and a 16
    49988 / AG
    E. Hawle Armaturen werke GmbH
    Derivation 4. The flow direction of the water is indicated by arrows. The device further comprises an electronic control unit 5, which is connected to all essential components of the device 1. The supply line 2 is connected directly to the main line 28 of the system.
    The filter unit 3 comprises a backwash filter 7 and is connected to the control unit 5. Furthermore, a backwash line 6, which opens into a drain 38, is provided for the purpose of diverting the filter cake formed during the filtration in the backwash filter 7. The rinsing process itself can be done manually or automatically. For this purpose, a pre-filter pressure sensor 8 is provided in the flow direction upstream of the filter unit 3, and a post-filter pressure sensor 9 is provided in the flow direction downstream of the filter unit 3. Both pressure sensors 8, 9 are connected to the control unit 5. If the pressure difference between these two pressure sensors exceeds a predetermined threshold value, the flushing of the backwash filter 7 is triggered. For this purpose, the filter unit 3 comprises a controllable by the control unit 5 drive 32. This is preferably designed as an electric motor.
    In the flow direction after the filter unit 3 is a disinfecting radiation source in the form of a UV reactor 10. This is also controlled by the control unit 5 and has a detection unit in the form of a photosensor 11, which measures the opacity of the treated medium and the determined value the control unit 5 passes. Depending on this measured value, the control unit 5 can control the UV reactor 10 or provide information about the functionality of the system and the quality of the filtered water.
    Furthermore, a seed connection 12 is provided in the flow direction downstream of the UV reactor, via which certain chemical substances or other materials can be added to the treated water. The dosage of the supplied substances can be done manually or by the central 17
    49988 / AG
    E. Hawle Armaturenwerke GmbH
    Control unit 5 are controlled or regulated. In particular, a sampling point 25, which is arranged downstream of the injection port, can be used to form a closed loop.
    The entire device is designed to be operated automatically by the control unit 5.
    Fig. 2 shows a further embodiment of the device according to the invention. In this embodiment, a normally open safety valve 13, a branch 37 to a fault line 14 and a normally closed safety valve 15 is provided in the flow direction directly in front of the discharge line 4. The discharge line opens into the backwash line 6.
    Both safety valves 13, 15 are controlled by the control unit 5. The flow direction of the medium is again indicated by arrows.
    By means of the safety valves 13, 15 according to the invention, the control unit can be closed via the safety valve 15 and the fault line 14 can be opened via the safety valve 13 in the event that contaminated water is detected in the system or another fault is noticed, whereby the contaminated water can flow through the branch 37 into the fault line 14. Likewise, in the event of an interruption of the power supply, the normally-open safety valve 13 is opened, and the normally-closed safety valve 15 is closed, whereby the water in the device is also conducted into the fault line 14. The fault line 14 opens into the backwash line 6, whereby the contaminated medium via the drain 38 into the sewer, a collection point or in the environment can be derived.
    Furthermore, in this exemplary embodiment, the device according to the invention comprises a static mixer 16, which is attached in the flow direction to the injection port 12 and for a mixing of the 4 * * t τ 4 4 ♦ * * * «I«
    18 49988 / AG
    E. Hawle Armaturenwerke GmbH provides any substances that may be supplied. Since in pipes usually constant flow conditions prevail, which in particular in laminar flows bring a poor mixing of the medium along the flow cross-section, there is a risk that the introduced substances are not evenly distributed over the entire pipe cross-section, but for example, an increased concentration in the middle of the pipe in the area of the highest flow velocity. In order to break the constant velocity profile and to favor the mixing of the water, the static mixer 16 is provided.
    Fig. 3 shows a further alternative embodiment of the device 1 according to the invention in the form of a water treatment plant. The contaminated water enters the main line 28 of the system at the supply line 2. The supply line 2 may preferably be provided with a pipe connection device. This pipe connection device is designed for example as a bayonet lock, flange, or the like. Furthermore, a slider can be provided in the region of the feed line 2. After the water has entered, the inlet pressure sensor 22 follows in the flow direction. This measures the pressure of the medium and forwards the measured values to the central control unit 5.
    After the inlet pressure sensor 22, the water passes through a slide 23. This slide is connected via a control line to the control unit 5. The spool of the slider 23 is motorized and can be operated by the control unit 5. Via the slide 23 can thus be controlled or controlled by the control unit 5 of the input mass flow and thus the pressure and flow conditions throughout the system. After the slider 23, a check valve and a pre-filter 24 is arranged. This prefilter 24 serves inter alia the component protection, in particular the protection of the «4
    19 49988 / AG
    E, Hawle Armaturenwerke GmbH downstream components. The prefilter 24 comprises in the illustrated embodiment a so-called strainer. This corresponds to a coarse filter that filters out water contaminants, such as solids with a size of 2 mm and more. Further, the prefilter 24 may also include oil separators as well as cyclones.
    The control valve 21 is located downstream in the system. This is set up to regulate the pressure and the flow of the system fluid. Due to the variety of applications, the pressure conditions and the flow conditions in the supply line 2 can vary widely. For example, if a pump for the promotion of groundwater to the supply line 2 is provided, this pump generates when starting shocks, which are compensated by the control valve 21. Even with water storage occurs when opening the slide to shocks whose pressure peaks must be compensated to protect the downstream components. The control valve 21 is therefore used in particular to reduce the inlet pressure to the operating pressure of the system.
    The control valve 21 is preferably designed self-venting. During initial startup, in which the pipe system, in particular the main line 28, is filled with air and only fills with the medium when the water flows in, the air which traps in cavities in the region of the control valve 21 is thus automatically discharged. To do this automatically, the control valve 21 is connected to the central control unit 5.
    Downstream of the flow direction, a prefilter pressure sensor 8 is provided. This pressure sensor is likewise connected to the central control unit 5 and, in combination with the inlet pressure sensor 22 and the differential pressure calculated therefrom, allows conclusions to be drawn about the flow conditions in FIG
    49988 / AG
    E. Ha as Armaturenwerke GmbH
    Area between the pressure sensors 8 and 22 to. After the pre-filter pressure sensor 8, a filter unit 3 is arranged.
    The filter unit 3 is designed to filter suspended particles from the system medium, in particular the contaminated water. For this purpose, different filter systems can be used for different applications. Preferably, an automatic backwash filter 7 is used. For example, jacket filters can also be used. To perform the automatic backwashing a controllable by the control unit 5 drive 32 is provided. Furthermore, the filter unit 3 has a ventilation valve 36.
    At the fitter unit 3, a slide 23 is mounted for emptying the filter unit, wherein the drain line 41 opens into the fault line 14 and, subsequently, in the drain 38.
    In the filter unit 3, a backwash valve 27 is provided, which is controlled by the control unit 5. The backwash valve 27 connects the backwash line 6 with the error line 14 described below when the backflushing process is activated, and subsequently discharges into the drain 38. Before the drain, another manual slide 23 is provided.
    The backwashing process can take place during the filtering process by activation of the backflushing valve 27 by the control unit 5.
    This sensor, which is also connected to the central control device 5, in combination with the prefilter pressure sensor 8, in particular on the calculated pressure difference, conclusions about the flow conditions in the range of the filter unit 3 to. If the differential pressure rises above a certain level, the backwashing of the filter unit 3 is initiated by the central controller 5, for example. As a rule, a strong * * * ·

    Subsequently, a bladder accumulator 20 may be provided. This bladder accumulator serves to equalize the pressure as well as to compensate for pressure or flow fluctuations. The bladder accumulator 20 is also connected to the central control device 5. Furthermore, 3 sampling points 25 can be provided in the area before and after the filter unit. These sampling points 25 are used, for example, the branching of a partial flow for feeding into an analyzer. This analyzer can also be connected to the central controller and allows, for example, conclusions about the quality of the main filtering.
    After these components, a non-return valve 29 is arranged. The check valve 29 is a bypass module 26 downstream.
    The bypass module 26 is used for looping additional modules in the water treatment system, in particular in the main line 28. For this purpose, an additional module is connected to the bypass ports 30 and 31. In order to guide the flow of the medium to the additional module, the bypass slide 33 is subsequently closed and the two bypass slides 34 and 35 are opened. Of course, it is also possible to use controlled valves or other devices instead of valves. As additional modules, for example, devices for ultrafiltration, activated carbon filters, chemical treatment devices, desalination modules, etc. are used.
    Also, the additional module used can be connected to the central control unit 5 and controlled by this or regulated. 22

    The bypass module 26 is in turn downstream of a sampling point 25 in the flow direction. This serves to check the quality of cleaning after the bypass module 26.
    Subsequent to the components mentioned, a UV reactor 10 is arranged. This serves to disinfect the water, in particular the harmlessness of viruses and bacteria, which are in the medium (water). The UV reactor 10 and the photosensor 11 for measuring the opacity of the medium disposed therein are connected to the central control unit 5. Furthermore, the UV reactor 10 has a slide 23 and a drain line 41, which opens in the error line 14 described below and finally in the drain 38. The UV reactor 10 can be operated by the control unit 5 via its own control line.
    Subordinate to the UV reactor 10 in the flow direction in this embodiment, a ventilation valve 36. This is used for venting when first filling the system with the medium, as well as for venting when draining the medium from the processing plant. Downstream of the UV reactor 10 is another sampling point 25.
    Downstream of the main line downstream there are a pressure sensor 17, a flow sensor 18 and a temperature sensor 19. Furthermore, in this area also sensors, such as particle counter, opacity meter, and / or chemical analysis devices, which also control the filter unit, the UV Can be used reactor or the vaccine port provided. The sensors 17, 18, 19 and the other enumerated sensors are connected to the central control unit 5.
    Downstream of the sensors 17, 18, 19 there is a static mixer 16. This serves to mix the flowing medium. This is a «♦ · * · # • •ιι« «« «« «« «« «« «« «« «« «« «« «« «« «« «« ««·························.

    E. Hawle Annaturenwerke GmbH is in turn located a sampling point 25 and a branch 37, which branches off a fault line 14 from the main line 28. Downstream of the branch 37 is located in the main water line 28, a safety valve 15, which is designed as open / close valve with check valve. This is connected to the central control unit 5 and can be opened and closed by this.
    In the fault line 14 is adjacent to the branch 37, a safety valve 13, which is designed as open / closed valve with check valve and is controlled by the central control unit 5. The valve 15 is designed as a normally closed valve and the safety valve 13 as a normally-open valve. These two valves serve to avoid the contamination in the event of a fault in the system, in particular the line of contaminated water to the discharge 4, which is designed as pure water outlet 39. If an error is detected by the central control unit 5, then the safety valve 15 is closed and the safety valve 13 is opened. As a result, the entire water flow of the system is directed into the fault line 14 and further discharged to the environment, a collection point or the sewer.
    In this embodiment, the fault line 14 opens in the backwash line 6 of the filter unit 3. However, it should be noted that the backwash line 6 of the filter unit 3 can also be arranged separately from the fault line 14.
    In the flow direction after the safety valve 15, a further pressure sensor 17 is provided along the main line 28. This is also connected to the central control unit 5 and serves to determine the output pressure after the filter and cleaning modules. Downstream of this, in turn, a sampling point 25 can be located, followed by a slide 23, and the discharge line 4, which is designed as pure water outlet 39. • ·
