EZ-Brine™

Aluminium in Ultrapurified Brine

The EZ-Brine™ on-line analyzer system monitors aluminium levels in ultrapurified brine, and enables operators 100% control over brine purity.

Background

Effect on membrane performance: aluminum forms sodium aluminosilicates, which precipitate near the membrane cathode layer, causing physical damage to the polymer and reducing the current efficiency. The source of aluminum, during the primary brine treatment, is from the clay in the salt. If filtration fails, the clay reaches the anolyte and dissolves, releasing the aluminum ions. The aluminum cations will pass into the membrane and change to the anionic form as they move toward the cathode side. The anionic aluminum will accumulate in the membrane by combining with other anions, such as silicates, and/or cations such as Na+, forming compounds that are precipitated, thereby damaging the membrane and reducing the current efficiency.

Other configurations

The EZ-Brine™ mainframe is also available in the following configurations: calcium and magnesium in ultrapurified brine, calcium and magnesium in prepurified brine, silica in ultrapurified brine, active chlorine in depleted brine, metabisulphite in depleted brine, sulphate in depleted brine.
