    [0002] Automated water quality control system in water producing stations, for example, for footwashes and beach showers
    [0004] The object of the present invention is to implement a system that allows the automatic control and monitoring of the water quality in water-producing stations for footbaths and beach showers, through the continuous acquisition of data on different parameters within the station, processing of said data, sending response signals to actuators that allow regulating said parameters, and an alarm system that alerts when the water parameters are at undesired levels.
    [0006] State of the art
    [0008] Document Es 2 140 994 B1 describes an installation for extraction, filtering, disinfection and supply of water, for example, for footbaths and beach showers.
    [0010] The installation described in the aforementioned document comprises a capture and filtration process using horizontal and / or vertical filtering drains located depending on the characteristics of the terrain and those of the water to be extracted, a process of suctioning the captured water using pumps, a tank that receives the water thus obtained, a pressurization system, a disinfection process using residual action disinfectants and / or a disinfection process carried out by the action of ultraviolet rays, and a connection to the external network by means of a booster pump.
    [0012] A problem that occurs in many beaches is that in many cases the origin of the water is unknown, it could be, for example, sewage, wastewater, etc.
    [0014] The ignorance of the origin of the water, together with the usual problems in water distribution facilities, causes the risk of the appearance and proliferation in the water present in the facility of various bacteria, which can cause diseases to users of the water. facilities, which can accidentally ingest water or absorb bacteria through mucous membranes.
    [0015] Legionella pneumophila is a bacterium that can colonize water distribution systems. In these facilities, as occurs in the facility described above, water stagnation and accumulation of products that serve as nutrients for the bacteria can occur. This bacterium can cause legionellosis, which is a disease that presents two different clinical forms, a lung infection or an acute febrile syndrome. The optimum growth temperature for these bacteria is 35 ° -37 ° C, and the pH ranges between 6.5 and 7.5. The National Institute of Safety and Hygiene at Work, determines as a means of prevention and control of Legionella that considerably reduces the risk of water contamination, that the temperature in cold water should never exceed 20 ° C.
    [0017] Escherichia coli belongs to a group of bacteria present in the intestine of humans and animals, the vast majority being harmless in them. However, there are some toxin-producing strains of E. coli called verotoxins or shiga-like toxins that can cause severe gastrointestinal conditions in humans. As the origin of the water captured by the installation's capture equipment is not known, these bacteria may be present in the installation's water. These bacteria multiply at temperatures between 6 and 50 ° C, with an optimum temperature around 37 ° C.
    [0019] The group of intestinal enterococci can also be used as an index of faecal contamination, since most species do not grow in aquatic environments. These bacteria tend to survive longer than E. coli (or thermotolerant coliforms) in aquatic environments, and are more resistant to desiccation and chlorination. Enterococci have a growth temperature of 35 ° C, and are tolerant to alkaline pH.
    [0021] For all of the above, the present invention provides an automated water quality control system in water producing stations, for example, for footbaths and beach showers, which allows controlling, monitoring and modifying different parameters that are growth factors of the bacteria mentioned, among others.
    [0022] Explanation of the invention
    [0024] The present invention, as discussed above, aims to ensure the quality of the water in water extraction and supply facilities, for example, for footbaths and beach showers.
    [0026] These facilities are made up of;
    [0028] - A process of capturing and filtering groundwater
    [0030] - A process of suction of the water captured by capture pumps
    [0031] - A tank that receives the water obtained.
    [0033] - A disinfection process carried out by means of residual action disinfectants injected into the tank by means of disinfectant injection systems and / or a disinfection process carried out by the action of ultraviolet rays, using emitters of ultraviolet light beams.
    [0035] - A connection to the external network by means of impulsion pumps.
    [0037] In accordance with the present invention, said facilities also have the following measuring instruments:
    [0039] - A counter for the continuous measurement of the flow thrown by the impulsion station.
    [0041] - A sensor for continuous measurement of the tank level.
    [0043] - A sensor for continuous measurement of the oxidation-reduction potential in the water in the decanter tank.
    [0045] - A sensor for the continuous measurement of the pH of the water in the decanter tank
    [0046] - A sensor for measuring the TOC of the tank.
    [0048] - A temperature sensor arranged in the tank.
    [0050] - A control body, which receives the signals from the measuring instruments.
    [0051] The present invention also includes the automation of the collection and impulsion pumps of the water extraction and supply facilities, as well as the automation of the disinfectant injection systems and the emitters of ultraviolet light beams.
    [0053] The present invention further comprises at least one monitoring device.
    [0054] The control body receives signals from the measuring instruments and determines a series of actions on the different automated elements.
    [0056] According to one embodiment, the system comprises elements for regulating the pH in the tank, such as, for example, a pH regulating solution consisting of a mixture in high concentrations of an acid and its conjugate base.
    [0058] Another object of the present invention is a procedure that determines, for the measured values of each of the parameters, the action to be performed, particularly the action to be performed on the automated elements.
    [0060] Flow
    [0062] When the flow meter sends to the control unit the signal indicating the flow produced by the impulsion station, the control unit analyzes said signal and is capable of acting on the collection pumps, the impulsion pumps, the injection systems. disinfectant, and ultraviolet light beam emitters.,
    [0063] When the flow sensor emits to the control body the signal that indicates the flow produced by the impulsion station, it also processes the data to obtain information such as volumes of water produced, levels and hours of use of the installation, number of uses of the facilities, in addition to providing relevant data for the preparation of a maintenance or equipment replacement plan.
    [0065] In particular, at least two operating states are defined, a normal state, in which the flow rate remains above a certain value, and an alert state, in which the flow rate remains below a certain value. When the operating state is normal, the control body does not issue any actuation signal to the automated elements. However, when the operating state is on alert, the control unit for the impulsion pumps, the catchment pumps, the pumps, impulsion, disinfectant injection systems, and ultraviolet light beam emitters, as well as emitting an alert signal.
    [0067] More particularly, the method defines three operating states as a function of the flow rate measured by the flow meter:
    [0069] • Normal state (> 20 m3): the control body does not issue any action signal.
    [0070] • Poor condition (10-20 m3): the control body does not issue any action signal.
    [0071] • Alert status (<10 m3): the control body stops the operation of the collection pumps, the impulsion pumps, the disinfectant injection systems, and the ultraviolet light beam emission systems.
    [0073] In addition to the measured flow values, an indication of the operating status of the system as a function of the flow rate is displayed on the monitoring device.
    [0075] Preferably, the impulse flow sampling period is one hour.
    [0077] level
    [0079] When the tank level measurement sensor emits the tank level signal, the control unit analyzes said signal and acts on the collection pumps and / or the impulsion pumps.
    [0081] In particular, the method of the present invention describes at least two operating states, a normal state, and an alert state. In a normal state, in which the level is above a minimum, the impulsion pumps and the collection pumps are not acted upon. In the alert state, the level value is below a minimum, and the control body determines the stoppage of the impulsion pumps, maintaining the actuation of the collection pumps.
    [0083] More particularly, the method defines three operating states as a function of the tank level:
    [0085] • Normal state (> 75%): In this state, the control body maintains the actuation of the injection and intake pumps.
    [0086] • Poor condition (25-75%): the control unit stops the impulsion pumps and keeps the collection pumps working.
    [0087] • Alert status (<25%): the control body stops the action of the collection pumps, the impulsion pumps, the disinfectant injection systems, and the ultraviolet light beam emission systems.
    [0089] In addition to the measured level values, an indication of the operating status of the system as a function of the level is displayed on the monitoring device.
    [0091] Preferably, the device level sampling period is seven minutes.
    [0092] Oxidation-reduction potential
    [0094] In water disinfection, the oxidation-reduction potential is very important. The World Health Organization adopted in 1971 a value of 650mV as a suitable value for drinking water,
    [0096] When the oxidation-reduction potential (ORP) measurement sensor emits the signal to the control body, it analyzes said signal and acts on the collection pumps, the disinfectant injection systems, and the ultraviolet light beam emitters.
    [0098] In particular, the method of the present invention describes at least two operating states, a normal state, and an alert state. In a normal state, in which the ORP is above a certain value, the collection pumps are not acted upon, and the disinfectant injection systems and the emitters of ultraviolet light beams remain deactivated. In the alert state, the ORP is below a certain value, and the control organ determines the stoppage of the collection pumps, and the activation of the disinfectant injection systems and emitters of ultraviolet light beams.
    [0100] More particularly, the procedure defines three operating states as a function of the ORP:
    [0102] • Normal state (> 650mV): In this state, the control body maintains the actuation of the collection pumps, and keeps the disinfectant injection systems and ultraviolet light beam emitters deactivated.
    [0103] • Poor condition (450-650mV): the control body maintains the action of the collection pumps, and activates the disinfectant injection systems and ultraviolet light beam emitters.
    [0104] • Alert state (<450mV): the control body stops the operation of the pumps and maintains the operation of the disinfectant injection systems and ultraviolet light beam emitters.
    [0106] Preferably, the ORP sampling period is ten minutes.
    [0108] In addition to the measured ORP values, an indication of the operating state of the system is displayed on the monitoring device as a function of the ORP.
    [0110] TOC
    [0112] TOC (Total Organic Carbon) is one of the parameters in the study of water pollution by organic compounds.
    [0114] When the TOC measurement sensor emits the signal to the control body, it analyzes said signal and acts on the collection pumps, the disinfectant injection systems, and the emitters of ultraviolet light beams.
    [0116] In particular, the method of the present invention describes at least two operating states, a normal state, and an alert state. In a normal state, in which the TOC is below a certain value, the capture pumps are not acted upon, and the disinfectant injection systems remain activated. In the alert state, the TOC is above a certain value, and the control body emits an alert signal and determines the stop of the disinfectant injection systems and the emitters of ultraviolet light beams.
    [0118] More particularly, the procedure defines three operating states as a function of TOC:
    [0120] • Normal state (<50ppm): In this state, the control body keeps the collection pumps activated, and stops the disinfectant injection systems and ultraviolet light beam emitters.
    [0121] • Poor condition (50-100ppm): the control body keeps the catchment pumps activated, and keeps the disinfectant injection systems activated. • Alert state (> 100ppm): the control body activates the emitters of ultraviolet light beams and stops the action of the disinfectant injection systems
    [0122] Preferably, the TOC sampling period is ten minutes.
    [0124] In addition to the measured TOC values, an indication of the operating status of the system based on TOC is displayed on the monitoring device
    [0126] pH
    [0128] The pH, as mentioned above, is a growth factor of some of the mentioned bacteria, so it is convenient to keep it below a certain level.
    [0130] When the pH measurement sensor emits the signal to the control body, it analyzes said signal and acts on the ultraviolet light emitters.
    [0132] In particular, the method of the present invention describes at least two operating states, a normal state, and an alert state. In a normal state, in which the pH is below a certain value, the ultraviolet light emitters are not acted upon. In the alert state, the pH is above a certain value, and the control body emits an alert signal and determines the activation of the ultraviolet light emitters.
    [0134] More particularly, the method defines three operating states as a function of pH:
    [0136] • Normal state (<7): In this state, the control body keeps the ultraviolet light emitters off.
    [0137] • Deficient state (7-9): In this state, the control body keeps the ultraviolet light emitters off.
    [0138] • Alert state (> 9): In this state, the control body determines the activation of the ultraviolet light emitters.
    [0139] Preferably, the pH sampling period is ten minutes.
    [0141] In addition to the measured pH values, an indication of the operating state of the system as a function of pH is displayed on the monitoring device
    [0143] Temperature
    [0145] Temperature, as mentioned above, is also a growth factor for some of the bacteria mentioned, so it is convenient to keep it below a certain value.
    [0147] When the temperature sensor emits the signal to the control body, it analyzes said signal and acts on the collection pumps, the disinfectant injection systems and the ultraviolet light emitters.
    [0149] In particular, the method of the present invention describes at least two operating states, a normal state, and an alert state. In a normal state, in which the temperature is below a certain value, it does not act on the ultraviolet light emitters or on the disinfectant injection systems, keeping the impulsion and collection pumps activated. In the alert state, the temperature is above a certain value, and the control body emits an alert signal and determines the activation of the ultraviolet light emitters, the disinfectant injection systems, and the stopping of the catchment pumps.
    [0151] More particularly, the procedure defines three operating states as a function of temperature: •
    [0153] • Normal state (> 20 ° C): In this state, the control body does not act on the ultraviolet light emitters or on the disinfectant injection systems, and keeps the impulsion and collection pumps activated
    [0154] • Deficient state (20-35 ° C): In this state, the control body determines the activation of the ultraviolet light emitters and the disinfectant injection systems.
    [0155] • Alert state (> 35 ° C): In this state, the control body determines the stoppage of the collection pumps, keeping the ultraviolet light emitters and the disinfectant injection systems active.
    [0157] Preferably, the temperature sampling period is ten minutes.
    [0159] In addition to the measured temperature values, the monitoring device displays an indication of the operating status of the system as a function of temperature.
    [0161] Also, to effectively control the growth of bacteria in the water of the facility such as Legionella pneumophila, intestinal enterococci. or E. Coli, the procedure includes periodic analysis in a laboratory of the water present in the facility to determine the quality of the water.
    [0163] In particular, Royal Decree 1341/2007, of October 11, on the management of the quality of bathing waters establishes the following levels, establishing a sampling period of 72 hours:
    [0165] Coastal and transitional water
    [0167]
    [0170] And Royal Decree 865/2003, of October 11, on the management of the quality of bathing waters establishes the following levels, establishing a sampling period of 15 days:
    [0173] According to a preferred option of the invention, the disinfectant is sodium hypochlorite (NaClO), and it is arranged in a disinfectant tank from which it is fed to the tank by means of a disinfectant drive pump.
