Groundwater remediation

Traditional methods

Innovative methods

Reverse osmosis Ex situ groundwater remediation

Description:

Filtration of extracted groundwater

Applying pressure to the groundwater on

one side of a selective membrane

Contaminants are retained on the

pressurized side of the membrane

Advantages

Suitable for wide range of contaminants including

inorganic salts

Cost effective – compared to evaporation
