REVERSE OSMOSIS FOR BRACKISH WATER

REVERSE OSMOSIS FOR BRACKISH WATER

Graver’s Reverse Osmosis Systems are pre-engineered to economically reduce total dissolved solids (TDS) by removing dissolved minerals, particles, and organic impurities. Each reverse osmosis system is specifically customized to the needs of your application and are compact with full integration for the ease of installation, operation, and maintenance.

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 generating make-up water for gas fired combined cycle power plants.  For high TDS waters, RO can be more cost effective than ion exchange, while having the added advantage of avoiding the use of acid and caustic. We can help you determine if RO is the best solution for your plant and provide a custom designed system for your application.
