    Abstract: A screen intake apparatus for a water intake system uses a cleaning system to clean one or more screen intakes. To clean debris from a screen, pipes in the interior of the screen receive pumped liquid (e.g., water or incompressible liquid) from a pump. Outlets, such as apertures or nozzles, on the pipes then direct the pumped liquid into the interior of the screen. One or more valves can vary, agitate, or pulse the flow of pumped fluid and/or can selectively deliver the pumped liquid to the pipes to remove collected debris from the exterior of the screen. A heater of the system can also heat the pumped liquid for delivery to the pipes to remove or prevent ice formation on the screen.

    Abstract: An improved method for separating solid particles from liquids, such as dewatering and thickening of sludge collected in a container (1), involves the use of at least one drainage unit (9) having doubled screened jacket walls (25, 26) defining a dewatering chamber (10). The liquid relieved of solids within the chamber is subjected to a turbulent motion acting against said screened jacket walls for obstruction of the solids deposition at the wall surfaces of the chamber facing the sludge in the container. The turbulent motion is obtained by a forced fluid F introduced in the chamber through one or more tubes (30, 31). The fluid may favorably be in form of compressed air or water returned from the reject system (14, 16).

    Abstract: In a system for separating solids from a liquid in a slurry, a filter apparatus is cleaned by a jet and a removal device. The filter is generally flat and has an inflow side on which the solids are deposited and an outflow side supported by a grid. The grid subdivides the outflow side into a plurality of separate injection chambers and defines a plurality of separate small regions of the filter. The jet directs a stream of liquid through one of the injection chambers and against one of the small regions of the filter defined by the injection chamber. A cover plate is provided on the jet for engaging the grid to close one injection chamber opposite the filter. The removal device is located on the inflow side of the filter and is aligned with the jet to receive solids dislodged from the filter. The jet and removal device move simultaneously and in alignment to close selectively and to direct a stream of liquid through each of the injection chambers.
