Ferric Alum Grade 4

Ferric aluminium sulphate grade 4 is a coagulant formulated for the treatment of potable water as well as process water, wastewater, sewage and industrial effluents. It works by neutralising the negative charge on suspended and colloidal matter to produce compact flocs suitable for easy removal by either settlement or flotation processes. Additionally, it promotes more efficient sludge digestion and dewatering.
