ORE Automatic Screen Filters
•Brochure: ORE Automatic Screen Filters
Automatic, self-cleaning, motorized water filter. Available in sizes from 2" to 24", single units can handle flow rates up to 9,000 gpm. Units can be installed in parallel to handle larger flow rates. Fine screens available down to 1500 mesh in multi-layer sintered stainless steel or wedgewire.
How It Works
The unit consists of two stages of filtration, a coarse pre-filter (1) and a stainless steel fine screen (2).
Dirty water enters the inlet (3), passes through the coarse screen and into the center of the fine screen. The water then passes through the fine screen from the inside out and exits the outlet (4).
The unwanted solids accumulate on the inner surface of the fine screen, creating a pressure differential. Once the pressure drop reaches a preset level, a rinse cycle is activated by the factory supplied control system by opening the rinse valves (5) to an atmospheric drain.
As a result, pressure drops in the backwash chamber (6) and dirt collector assembly (7). The pressure drop creates a backflush stream, which sucks the dirt off the screen, similar to a vacuum cleaner. The backwash water is carried through the collector and ejected out of the holes in the base of the collector.
At the same time, the drive assembly (8) controls the movement of the collector assembly, ensuring that the collector nozzles sweep the entire screen area in a helical fashion, and returning the collector to its original position in preparation for the next cycle.
