How the brine operation works?

Simple sketch of the process of saturated brine production: 

how amine works


  1. Saturated Brine is treated with chemicals
  2. The insoluble compounds formed are removed in a settling tank
  3. The particles in the overflow are removed in a filtration system which can consist out of a precoat filtration unit with cellulose (brine-aid) filteraid
  4. Sparkling clean saturated brine solution enters the membrane cell

Brine filtration solution

Among the brine production process there are several filtration systems involved, Sulphurnet offers both non-pre-coat membrane filters and pre-coat type filters. Filters are fully rubber lined and internals are manufactured from Titanium and polypropylene.
