“PROTECT MEMBRANES.” That’s the mantra permeating the minds of ORIVAL filtration specialists as they design pretreatment systems for membrane applications. ORIVAL ORG Series of automatic self-cleaning screen filters are specifically designed for small to medium size MF/UF membrane systems requiring pretreatment in the 100-500 micron range. Their compact size and L-configuration lend themselves greatly to the densely packed piping of membrane skids. For NF/RO systems ORIVAL filters can be the first stage of pretreatment with screen apertures as low as 5 microns. These would be followed by 1-3 micron cartridge filters for final polish before sending the water to the membrane vessels. ORIVAL OR and ORE Series of automatic filters are designed for higher flow rates for large municipal/industrial membrane systems. Whether sourced from ground water or surface water, ORIVAL provides the protection needed for all types of membrane systems.
