Reverse Osmosis for Waste Water Recycle/Reuse

Graver’s Reverse Osmosis Systems are pre-engineered to economically reduce total dissolved solids (TDS) by removing dissolved minerals, particles, and organic impurities. When used in conjunction with Graver supplied pretreatment equipment such as clarifiers, filters and chemical feeds, the Graver Reverse Osmosis Systems provide an economical means for treating wastewater for recycle and reuse within your plant.  Freshwater sources are dwindling and the cost are increasing as your needs complete for the same water used for municipal drinking.
