Reverse osmosis (RO) continues to gain favor as a ,method, for pre-,treating, makeup for steam boilers. The RO process produces a continuous supply of softened and dealkalized water for this application. The downside of RO is that it produces a continuous waste stream that is sent to drain. 25% of the feedwater to the RO is lost to drain while 75% is recovered for use as boiler makeup.

In cases where the wastewater to be treated originates from industry, suggesting the presence of mineral acids or acid salts, neutralisation must take place beforehand. Ferrous sulphate and lime Ferrous sulphate is not usually used alone, but added simultaneously with lime for the formation of precipitate (added in excess in cases where the alkalinity is low).
