This 1320 L/min reverse osmosis water treatment plant, containing two identical 3-stage RO modules, is the largest unit of this kind ever manufactured by BI Pure Water. It includes 18 vessels with four RO membranes in each vessel and a separate CIP (clean-in -place) system, allowing cleaning of each stage individually or, if so desired, of all three stages simultaneously. Recovery is 80%. A fraction of the incoming well water stream is subjected to greensand filtering for removal of iron and manganese, and mixed in with the treated RO stream before disinfection with chlorine and storage
