Galvatek delivered the previous water treatment plant, a desulphurization line, for Hitachi's coal power plant in Poland three years ago. Customer satisfaction in the delivery and features of desulphurization line made for a solid basis for a new contract. The new water treatment plant will clean the waste water coming from the coal power plant's flue gas desulphurization. The waste water is neutralized, and heavy metals and solids are separated. The purified water is then recycled to the environment.
