Pretreatment

High pressure water treatment systems require water sources be conditioned to only contain dissolved ions. Constituents in feed water such as suspended solids, scaling potential, microbial content and organic particulates can lead to fouling. Reversible or irreversible fouling of the membrane surface reduces membrane life and increases membrane cleaning requirements. These factors increase the cost of membrane treatment. Research has focused on the following categories to improve general pretreatment processes:
