The last water treatment system used for removing sulphate from water is distillation, which boils water and cools the steam until it condenses into a different container. Sulphate, as do other dissolved solids and chemicals stay in the boiling pot. If completely function, distillation systems effectively remove virtually 100% of sulfate from ...
MoreReverse Osmosis (RO) is a water treatment system that removes most dissolved substances, such as sulfate, from water by forcing the water through a cellophane-like plastic sheet known as a "semipermeable membrane." It can typically remove between 93 and 99 percent of the sulfate in drinking water depending on the type of unit.

MoreThe most common method for removing high concentrations of sulfate from water is through addition of hydrated lime (Ca (OH)2), which precipitates calcium sulfate: Na 2 SO 4 + Ca (OH) 2 => CaSO 4 + 2 NaOH Calcium sulfate, which hydrates to become the common mineral gypsum, has a solubility of approximately 2000 mg/L as sulfate.
More2016-10-1 The aim of this research was to investigate sulphate removal from mine water by precipitation as ettringite (Ca 6 Al 2 (SO 4) 3 (OH) 12 26H 2 O) and the utilisation of the precipitate as a sorbent for arsenate removal. The mine water sulphate concentration was reduced by 85–90% from the initial 1400 mg/L during ettringite precipitation depending on the treatment method.

So, its important to be aware of sulphate levels in your water and understand how to remove it. There are three key methods used to remove sulphates from water:
More2017-11-6 water runs in river streams, ponds, lakes and dams. The presence of sulphates in water has been considered as one of the most consequential water quality issues for mining operations and process plants, especially in countries that have problems of fresh water supply like South Africa and Australia [4].
