Water treatment
Iontech provides sustainable wastewater treatment solutions based on latest and time tested technology. Our specialties are:
-
Heavy metals removal – removal of dissolved metals like lead, mercury, cadmium iron, aluminum, antimony, chromium/chrome, cobalt, copper, manganese, nickel, uranium, vanadium and zinc using the following approaches:
-
Ion Exchange process
-
High Density Sludge (HDS) lime neutralization process
-
Sulfate removal
-
chemical treatment with mineral precipitation - the main reagents used are: lime, limestone, barium salts {Ba(OH)2, BaCO3 and BaS}, aluminum hydroxide, CO2
-
semi-permeable membranes – two water treatment processes are used Electrodialysis and Reverse Osmosis
-
ion-exchange – specially developed ion exchange resins are used
-
biological sulphate removal - constructed wetlands, anoxic limestone drains and permeable reactive barriers are used
-
Arsenic removal
-
two-stage precipitation of arsenic as scorodite
-
final removal of arsenic using specially designed ion exchange resin
