Brackish Water

Forsta self-cleaning filters for brackish water filtration remove suspended solids, protecting downstream equipment and processes, with materials designed for corrosion resistance.

All Details at a Glance

Brackish water is water occurring in a natural environment having more salinity than freshwater, but not as much as seawater. It may result from mixing seawater (salt water) with fresh water together, as in estuaries, or it may occur in brackish fossil aquifers. All water naturally contains dissolved solids that, if present in sufficient concentration, can make a surface-water or groundwater resource “brackish”, typically defined as distastefully salty. Although quantitative definitions of this term vary, it is generally understood that brackish groundwater is water that has greater dissolved-solids content than occurs in freshwater, but not as much as seawater (35,000 milligrams per liter). It is considered by many to have dissolved-solids concentration between 1,000 and 10,000 milligrams per liter (mg/L). The term “saline” commonly refers to any water having dissolved-solids concentration greater than 1,000 mg/L and includes the brackish concentration range.

Brackish groundwater is directly used for purposes such as cooling water for power generation, aquaculture, and for a variety of uses related to drilling. For purposes requiring lower dissolved-solids content, especially drinking water, brackish water is treated through reverse osmosis or other desalination processes.
