Our DESALX® technology consists of two CIF® (continuous ionic filtration) modules in series removing multivalent cations (such as calcium and magnesium), and then multivalent anions (such as sulphate) present in the water through a complementary processes.

Monovalent ions such as sodium and chloride pass through the system, avoiding creating a saline brine. DESALX® produces a gypsum based brine which can be paired with existing lime precipitation systems on site to produce gypsum solids for a true zero liquid discharge (ZLD) solution. If lime precipitation isn’t available, DESALX® can be used with a high density sludge (HDS) clarifier to achieve ZLD.
