ORG Series - Automatic Self-Cleaning Water Filters
Automatic, self-cleaning, line pressure powered water filter. Orival's ORG model filters are available in sizes from 1-1/2'' to 8'', and can handle flow rates up to 1320 gpm. These units can be installed in parallel to handle larger flow rates. Fine screens are available down to 1500 mesh in a variety of constructions, including standard stainless steel mesh, multi-layer sintered stainless steel and wedgewire. The high efficiency rinse cycle consumes a fraction of the water of standard filters.
The ORG series units from Orival Inc. are designed to provide efficient, reliable filtration while reducing the amount of backwash water required. Thanks to its efficient rinse system, the ORG uses approximately 90% less than conventional self cleaning units. This low consumption makes it the ideal unit for a wide variety of applications.
Technical Specifications for the ORG Series
- Maximum working pressure: 150 psig (high pressure units available upon request)
- Maximum fluid temperature: 150°F(high temperature units available upon request)
-
Standard housing constructed of carbon steel, coated with extra durable polyester, electrostatically applied and oven cured on a zinc phosphate layer. Alternate materials of construction or special coatings available on request
- ASME units available - with or without ''U'' stamp
- Units can be manifolded together to handle unlimited flow rates -- see our Flange-to-Flange Solutions for details
Working of the ORG Series of Water Filters
Dirty water enters the inlet, where it enters the center of the fine screen. The water then passes through the fine screen from the inside out and exits the outlet.
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 control system by opening the rinse valve to an atmospheric drain.
As a result, pressure drops in the hydraulic motor chamber and dirt collector assembly. 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 hydraulic motor.
The water being ejected out of the hydraulic motor causes the collector to rotate, similar to a sprinkler. In addition, the pressure drop in the hydraulic motor chamber causes the collector assembly to move axially. This combination of movements ensures that the entire screen area is cleaned each cycle.
ORV Series - Automatic Self-Cleaning Water Filters
The ORV series units from Orival provide efficient and reliable filtration while conserving the amount of backwash water required. Due to its efficient rinse system, the ORV uses 1 to 2 gallons per rinse cycle. This low consumption makes it the ideal unit for a wide variety of applications. Designed for low flow applications, the unit is available with 3/4'' and 1'' inlet and outlet, to handle flow rates up to 27 gpm. The stainless steel fine screen is available in a variety of sizes to suit any application.

Working of the ORV Series of Water Filters
Dirty water enters the inlet into the center of the fine screen. The water then passes through the fine screen from the inside out and exits to the outlet.
The unwanted solids accumulate on the inner surface of the fine screen, building up a filter cake which filters out even finer particles, creating a pressure differential. Once the pressure drop reaches a preset level, a rinse cycle is activated by the control system, opening the rinse valve to an atmospheric drain and closing the optional controlled outlet valve (C.O.V.).
As a result, pressure drops in the hydraulic motor chamber and the dirt collector assembly. 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 nozzles and the direct collector tube before being ejected out of the holes in the hydraulic motor.
The water being ejected out of the hydraulic motor causes the direct collector to rotate, similar to a sprinkler. In addition, the pressure drop in the hydraulic motor chamber forces the dirt collector assembly to move axially, controlled by hydraulic piston (10). This combination of movements ensures that the entire screen area is cleaned each cycle.
