Industrial customers have high requirements for process water in the production and manufacturing process, even some special industries have special standards for water composition, such as hardness. Keysino's solution is equipped with unique membrane separation device that effectively removes calcium and magnesium ions and other harmful substances from natural or tap water to meet production water requirement.

Softened water is a kind of production water after softening treatment, with relatively low content of calcium and magnesium ions. Some special industries, such as printing and dyeing, have special requirements for water quality in production and manufacturing, requiring softened water with hardness less than 60ppm. By using the world's advanced standard nanofiltration membrane (NF) and reverse osmosis membrane (RO), Keysino’s solution Keysino's solution could radically reduce the hardness of water.
