Control mechanism for self-cleaning filtration systems

A filtration system (100) comprising:

• a filtration chamber (101);
• an environment (106c) isolated from fluid content of the filtration chamber (101);
• a screening element (103) located within the filtration chamber (101);
• a suction scanner (104) for self-cleaning the screening element (103) by suctioning fluid through the screening element (103) upon activation of a self-cleaning session;
• a location tracker (106) that comprises a moving body (106p) coupled to the suction scanner (104), wherein the moving body (106p) is linearly movable within the environment (106c);
• at least one pressure detector for detecting a change in a pressure within the environment (106c) resulting from the moving body (106p) moving linearly within the environment (106c) during the self-cleaning session;
• an electronic controller (105) configured to terminate the self-cleaning session;
• wherein during the self-cleaning session, the suction scanner (104) moves linearly across the screening element (103), thereby cleaning the screening element (103) and causing the moving body (106p) to move linearly within the environment (106c);
• wherein upon the moving body (106p) reaching a predetermined location in the environment (106c), the location tracker (106) communicates a signal based on an output of the pressure detector to the electronic controller (105), wherein said signal is indicative of the suction scanner (104) completing a linear motion within the filtration chamber (101);
• and
• wherein the electronic controller (105) determines whether to terminate the self- cleaning session based on said signal.
