    The present invention relates to a system for uninterrupted (continuous) water filtration with automatic filter cleaning.
    Numerous systems for water filtration and filter cleaning are well known: a system with alternating water filtration and filter cleaning, systems for filter cleaning with brushes, and others.
    A common problem of all these systems is the inability of a continuous water filtration with a simultaneous automatic filter cleaning, as well as the clogging of the pores with colloid particles or a biofilm. In the case of the majority of the previous systems for water filtration, the water filtration must be interrupted when the process of filter cleaning begins. Because of the above problem, the final capacity of the filtered water is greatly reduced, and the maintenance cost of the whole system is much higher. With the introduction of the system for uninterrupted water filtration with automatic Fil¬terreinigung the water filtration is effective and cheaper. The system has an uninterrupted operation, which substantially contributes to the final capacity of the filtered water and thus eliminates all possible disturbances due to the interruption of the clean water supply. With such a system, operating costs are greatly reduced because the entire process of water filtration and filter cleaning is fully automated and human intervention is no longer necessary. The maintenance costs are also reduced, since due to the automatic and frequent filter cleaning eliminates the mechanical filter cleaning with different brushes or other means. The ability of uninterrupted automatic filter cleaning without interruption of the water filtration also allows Filtra¬ tion of numerous highly loaded media that could not be filtered because of the required for filter cleaning numerous interruptions. Furthermore, in the case of mechanical water filtration, the order of the filters and the ratio between the input and output pores are also important. In the systems known hitherto, it is necessary to use a filter arrangement in which the filters are each lined up after the filters with the widest pores up to the filters with the narrowest pores. If heavily contaminated water is to be filtered to a particle size of 50 microns, a filter assembly must be assembled in the following order: a 300 micron mesh filter, then a 200 micron mesh filter, then a 150 micron mesh filter, then a 100 micron mesh filter Micron and in the end 50 microns. Nevertheless, there is a high probability that one of the filters will become clogged much faster than the other, reducing or interrupting the water flow. The system for uninterrupted water filtration with automatic filter cleaning offers the possibility that a large ratio between the pore widths is present in a filter; the egg spore has a width of 30 millimeters and the exit pores a width of 50 microns. And that is exactly the Tat¬ thing that makes it possible to clean even very polluted waters. However, the continuous filtration water filtration system with automatic filter cleaning is also ideally suited as a prefilter for ultrafiltration, nanofiltration, reverse osmosis, ion exchange, desalter and hundreds of other industrial applications where fluids are filtered.
    There are already some inventions or patents in the field of water filtration. The existing patents provide a solution to various segments of the problems that arise in the water filtration systems. However, the inventors of the existing patents are not aware of a solution in the form of an invention or of a patent which advantageously solves the previously described existing problems.
    The invention solves the problems with the features of claim 1. Advantageous developments of the invention are set forth in the subclaims.
    In detail, the invention of the system for continuous Wasserfilt¬ration with automatic filter cleaning comprises a first filter assembly A, a second filter assembly B and a control unit K. The first filter assembly A consists of a first filter unit F1, a second filter unit F2, a first Eingangsgangsventileinheit V1, a first outlet valve unit 11, a second inlet valve unit V2, a second outlet valve unit I2 and a first central valve unit CA. The second filter arrangement B consists of a third filter unit F3, a fourth filter unit F4, a third input valve unit V3, a third output valve unit I3, a fourth input valve unit V4, a fourth output valve unit I4 and a second central valve unit CB. Each valve unit V1, V2, V3, V4, 11, 12, 13, 14, CA, CB consists of an electric valve E and a communication arrangement L. The control unit K consists of a process unit P and a communication arrangement L.
    The communication between each valve unit V1, V2, V3, V4, 11, 12, 13, 14, CA, CB and the control unit K is via the communication link L1. In the control unit K program instructions are executed by means of the process unit P, which are then transmitted by means of the communication arrangement L via the communication connection L1 to each valve unit V1, V2, V3, V4, 11, 12, 13, 14, CA, CB. In each valve unit V1, V2, V3, V4, 11, I2, I3, I4, CA, CB, the program commands are then received by means of the communication arrangement L and then in the form of opening or closing the solenoid valve E in the valve unit V1, V2, V3, V4 , 11, 12, 13, 14, CA, CB. The system for continuous water filtration with automatic filter cleaning according to the invention is achieved by a coordinated operation of all valve units V3, V4, 11, 12, 13, 14, CA, CB based on electric valves E or other automatic valve-based units.

    The process for continuous water filtration with automatic filter cleaning can be described with a continuous cyclical operation of 6 successive phases: 1st phase: The first filter arrangement A filters the water and the second filter arrangement B rinses out the water. 2nd phase: The first filter arrangement A filters the water and the third filter unit F3 cleans the fourth filter unit F4. 3rd phase: The first filter arrangement A filters the water and the fourth filter unit F4 cleans the third filter unit F3. 4th phase: The first filter arrangement A rinses out the water and the second filter arrangement B filters the water. 5th phase: The first filter unit F1 cleans the second filter unit F2 and the second filter assembly B filters the water. 6th phase: The second filter unit F2 cleans the first filter unit F1 and the second filter assembly B filters the water. 1st phase:
    In the control unit K, by means of the process unit P, the program instructions begin to carry out the process of continuous water filtration with automatic filter cleaning. The program instructions are transmitted by means of the communication arrangement L in the control unit K via the communication link L1 into the communication arrangement L of each valve unit V1, V2, V3, V4, 11, 12, 13, 14, CA, CB in the system. Thus, all four input valves V1, V2, V3, V4 in both filter arrangements A, B receive a command for a free flow of the unfiltered water NV into all four filter units F1, F2, F3, F4 and therefore all four solenoid valves E open in all Eingangsventilein¬heiten V1, V2, V3, V4. In the first filter arrangement A, both outlet valve units 11, 12 receive a command to prevent the flow of the flushed water OV from both filter units F1, F2 and the solenoid valves E in both outlet valve units 11, 12 are closed. In the first filter array A, at the same time, the first central valve unit CA also receives a command for the free flow of the filtered water FV from the two filter units F1, F2 and the solenoid valve E in the first central valve unit CA is opened. At the same time, the two receive in the second filter assembly B Ausgangsventi¬leinheiten I3,14 a command on the free flow of the flushed out water from the two filter units F3, F4 and the solenoid valves E in both Aus¬gangsventileinheiten I3, I4 are opened. In the second filter arrangement B, the second central valve unit CB simultaneously receives a command to interrupt the flow of the filtered water FV from the two filter units F3, F4, and the electric valve E is closed in the second central valve unit CB. 2nd phase:
    After a certain time interval predetermined in the stereo unit K, the program commands via the communication connection L1 are simultaneously transmitted from the control unit K to the fourth input valve unit V4 and to the third output valve unit I3 in the second filter arrangement B. The fourth input valve unit V4 receives the command for interrupting the flow of the unfiltered water NV into the fourth filter unit F4, and the electric valve E in the fourth input valve unit V4 is closed.

The fourth input valve unit V4 receives the command for a free flow of the unfiltered water NV in the fourth filter unit F4 and the solenoid valve E in the vier¬ten input valve unit V4 is opened.

The fourth output valve unit I4 receives a command for interrupting the flow of the purged water OV from the fourth Fil¬tereinheit F4 and the solenoid valve E in the fourth output valve unit I4 is closed. 4th phase:
    After the lapse of a specific time interval predetermined in the stereo unit K, the program commands via the communication link L1 are simultaneously transferred to the third input valve unit V3, the third output valve unit I3 and the second central valve unit CB in the second filter array B as well as into the first output valve unit 11, the second Ausgangsventilein¬heit I2 and the first central valve unit CA in the first filter arrangement A transmits. The third input valve unit V3 receives the command for the free Durchfluß the unfiltered water NV in the third filter unit F3 and the ElektroventilE in the third input valve unit V3 is opened. The third output valve unit I3 receives a command to interrupt the flow of the purged water OV from the third filter unit F3 and the electric valve E in the third output valve unit I3 is closed. The second central valve unit CB receives the command for the free flow of the filtered water FV from the third and fourth filter units F3, F4 and the electric valve E in the second central valve unit CB is closed. The first output valve unit 11 receives the command for the free flow of the flushed out water OV from the first filter unit F1 and the electric valve E in the first outlet valve unit 11 is opened. The second output valve unit I2 receives the command for the free flow of the purged water OV from the second filter unit F2, and the electric valve E in the second output valve unit I2 is opened. The first central valve unit CA receives the command for the interruption of the free flow of the filtered water FV from the first and second filter units F1, F2, and the electric valve E in the first central valve unit CA is closed. 5th phase:
    After a certain time interval predetermined in the stereo unit K, the program commands via the communication connection L1 are simultaneously transmitted from the control unit K to the second input valve unit V2 and to the first output valve unit 11 in the first filter arrangement A. The second one-port valve unit V2 receives the instruction to interrupt the flow of the unfiltered water NV into the second filter unit F2, and the electro-valve E in the second input valve unit V2 is closed. The first output valve unit 11 receives the command for interrupting the free flow of the purged water OV from the first filter unit F1, and the electric valve E in the first output valve unit 11 is closed. 6th phase:
    After a certain time interval predetermined in the stereovision unit K, the program commands via the communication link L1 are simultaneously transmitted to the two input valve units V1, V2 and into the two output valve units 11, 12 in the first filter arrangement A from the control unit K. The first input valve unit V1 receives the Instruction for interrupting the flow of the unfiltered water NV into the first filter unit F1 and the electric valve E in the first input valve unit V1 is closed. The second input valve unit V2 receives the command on the free flow of the unfiltered water NV in the second filter unit F2 and the electric valve E in the second input valve unit V2 is closed. The first output valve unit 11 receives the command for the free flow of the purged water OV from the first filter unit F1 and the solenoid valve E in the first output valve unit 11 is opened. The second output valve unit I2 receives the instruction for interrupting the flow of the purged water OV from the second filter unit F2, and the electric valve E in the second output valve unit I2 is closed.
    After the first cycle of the alternating repetition of water filtration and cleaning of the filter units F1, F2, F3, F4 between the two filter arrangements A, B has ended, the process of water filtration with automatic filter cleaning is repeated in the same sequence.
    In summary, the process of continuous water filtration with automatic filter cleaning begins with the transmission of the program instructions from the control unit K via the communication link L1 to each valve unit V1, V2, V3, V4, 11, 12, I3, 14, CA, CB in the system. The first filter arrangement A begins the process of water filtration and thus opens the first input valve unit V1, the second input valve unit V2 opens, the first output valve unit 11 closes, the second output valve unit I2 closes and the first central valve unit CA opens. In this case, unfiltered water NV enters the first and second filter units F1, F2 through the first and second input valve units V1, V2. From the first and second filter units F1, F2, filtered water FV then exits through the first central valve unit CA. Meanwhile, the second filter assembly B performs the process of purging the filter units F3, F4 and the third input valve unit V3 opens, the fourth input valve unit V4 opens, the third output valve unit I3 opens, the fourth output valve unit I4 opens and the second central valve unit CB closes , In this case, unfiltered water NV enters the third and fourth filter units F3, F4 through the third and fourth input valve units V3, V4. From the third and fourth filter units F3, F4, flushed out water OV then exits through the third and fourth outlet valve units I3, I4.
    After a certain time interval, the process of water filtration always proceeds in the first filter arrangement Anoch, while in the second filter arrangement B, the cleaning process of the fourth filter unit F4 begins. Therefore, the fourth input valve unit V4 closes and the third output valve unit I3 closes. In this case, unfiltered water NV enters the third filter unit F3 through the third inlet valve unit V3. Filtered water FV then flows out of the third filter unit F3 into the fourth filter unit F4 and exits as flushed out water OV through the fourth outlet valve unit I4.
    After a certain time interval, the process of water filtration always proceeds in the first filter arrangement Anoch, while in the second filter arrangement B, the cleaning process of the third filter unit F3 begins. Therefore, the third input valve unit V3 closes, the fourth input valve unit V4 opens, the third output valve unit I3 opens and the fourth output valve unit I4 closes. In this case, unfiltered water NV enters the fourth filter unit F4 through the fourth input valve unit V4. Filtered water FV then flows out of the fourth filter unit F4 into the third filter unit F3 and exits the third output valve unit 13 as purged water OV.
    After a certain time interval has elapsed, the process of flushing the filter units F1, F2 starts in the first filter arrangement A, and therefore the first outlet valve unit I2 opens, the second outlet valve unit I2 opens and the first central valve unit CA closes. In this case, unfiltered water NV enters the first and second filter units F1, F2 through the first and second input valve units V1, V2. From the first and second filter units F1, F2, the purged water OV then exits through the first and second output valve units 11, 12. In the meantime, the second filter arrangement B starts the process of filtering the water and therefore the third input valve unit V3 opens, the third output valve unit I3 closes and the second central valve unit CB opens. In this case, unfiltered water NV enters the third and fourth filter units F3, F4 through the third and fourth input valve units V3, V4. From the third and fourth filter units F3, F4, filtered water FV then exits through the second central valve unit CB.
    After a certain time interval has elapsed, the process of cleaning the second filter unit F2 begins in the first filter arrangement A. Therefore, the second input valve unit V2 closes and the first output valve unit 11 closes. In this case, unfiltered water NV enters the first filter unit F1 through the first input valve unit V1. Filtered water FV then flows out of the first filter unit F1 into the second filter unit F2 and exits as flushed out water OV through the second outlet valve unit I2. Meanwhile, in the second filter arrangement B, the process of water filtration is still running.
    After a certain time interval has elapsed, the process of cleaning the first filter unit F1 begins in the first filter arrangement A. The first input valve unit V1 closes, the second input valve unit V2 opens, the first output valve unit 11 opens and the second output valve unit I2 closes. In this case, unfiltered water NV enters the second filter unit F2 through the second input valve unit V2. Filtered water FV then flows out of the second filter unit F2 into the first filter unit F1 and exits through the first output valve unit 11 as purged water OV. Meanwhile, in the second filter assembly B, the process of water filtration still proceeds.
    After the first cycle of the alternating water filtration and the cleaning of the filter units F1, F2, F3, F4 has ended between the two filter arrangements A, B, the process of water filtration with automatic filter cleaning is repeated in the same sequence.
