Patent number: 6267879Abstract: Described is a continuous liquid filtering apparatus having a preliminary filtering chamber 9, a filtering chamber 3, a filtered liquid chamber 12, and an electromechanical cleaning system. In operation, after entering inlet 1, liquid passes through coarse screen 2 into the filtering chamber 3. The liquid then passes through a multi-layer sintered filtering element 4 before exiting the apparatus through the outlet 6. The electromechanical cleaning system includes a hollow connector unit 10 having dirt suctioning members 5 and spraying nozzles 11 for cleaning the sintered filter element. The cleaning system is activated whenever the liquid differential pressure exceeds a predetermined valve indicating that the cylindrical filter requires a cleaning treatment. The spraying nozzles 11 are in fluid communication with the filtered liquid chamber 12 via booster pump 13.Type: GrantFiled: August 11, 1999Date of Patent: July 31, 2001Assignee: Odis Irrigation Equipment Ltd.Inventor: Shemuel Gil

Patent number: 5082560Abstract: A method and apparatus for treating a liquid mixture to separate a clarified fraction therefrom leaving a concentrated sludge fraction involve injecting a flocculent material into the liquid mixture; and inletting the liquid material and the flocculent maerial tangentially into a vertical tank having a perforated plate spaced from its upper end dividing the tank into an upper chamber and a lower chamber, a to produce a flow in the lower chamber having a rotational velocity in the horizontal direction adjacent the outer periphery of the lower chamber, and a lower rotational velocity in the horizontal direction adjacent the center of the lower chamber. The holes in the perforated plate define reduced-area passages from the lower chamber to the upper chamber producing a vertical flow of low velocity in the lower chamber and of higher velocity through the passage in the perforated plate.Type: GrantFiled: March 9, 1990Date of Patent: January 21, 1992Assignee: Odis Irrigation Equipment Ltd.Inventors: Nissim Eli, Albert Marrache
