Regions of fresh water scarcity look to newterra for modular, energy efficient treatment solutions for brackish water and seawater to provide source water for industry and drinking water for resorts and communities.

Look to COCHRANE by newterra for high pressure membrane systems.

Treatment Targets:

Dissolved solids
newterra membrane desalination solutions for the desalination of brackish water and seawater incorporate advanced energy recovery components to minimize operating costs of these high pressure systems. Dissolved solids in process water can erode efficiency by increasing boiler blow down and causing scaling. The process flow of newterra desalinations systems is much the same as our RO and nanofiltration system. A key distinction is much higher pressures required to overcome the osmotic pressure of seawater. Pre-filtered feed water is pumped under very high pressure into the desalination skid, where it flows through the membrane array where the majority of the dissolved solids are rejected. These build up in the concentrate stream of the membrane skid, which is discarded. Treated permeate is sent to a storage tank.
