EZ-Brine™

Silica in Ultrapurified Brine

In electrolysis processes, a synergy between silica and aluminium exists that can lead to the formation of complex crystalline aluminosilicates within the membrane. The consequence is a loss in current efficiency. Aluminum, if present in sufficient concentration, will also precipitate at the anode/membrane interface. This causes a very slight increase in voltage that can be reversed when the electrolyzer shuts down. Problems with aluminum and silica sometimes occur when vacuum purified salt is used without primary chemical treatment. That part of the process often removes most of these secondary impurities by co-precipitation. Contamination by filter media is usually avoided by proper selection of materials.

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

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, aluminium in ultrapurified brine, active chlorine in depleted brine, metabisulphite in depleted brine, sulphate in depleted brine
