SAL-PROC™

SAL-PROC™ is a proprietary integrated process for the sequential or selective extraction of dissolved elements from saline effluents, in the form of valuable salts and chemical compounds (mineral, slurry, and liquid form). The process involves controlled chemical reactions, using non-hazardous chemicals, combined with evaporation/cooling steps, causing precipitation and crystallisation.

Depending on the chemical composition of the saline feed water, the process route may involve one or more steps of reaction and evapo-cooling, supplemented by conventional mineral and chemical processing steps. The technology is based on simple closed-loop processing and fluid flow circuits, which enable the partial or comprehensive treatment of saline streams for recovery of valuable byproducts. These process steps lead not only to significant salt load reduction (thus minimising the requirements for land-filling of the residual solids), but also act as pre-treatment for achieving higher-efficiency volume reduction, using membrane desalination/distillation and thermal volume reduction equipment. The key attributes of SAL-PROC™ are: less solids for landfill disposal and smaller footprint of volume reduction processes; these translate to significant cost efficiency and operation improvement of the total treatment system.
