Central water treatment plant for boiler feed, cooling and process
The customer is a technology leader in transforming steel wire and applying advanced coating know-how. In the process of adding new production lines to the facility, it was decided to optimize the supply of different water qualities by building a centralized water treatment plant.
Raw water is supplied by local municipality. First treatment step is nanofiltration. The treated water is used as make-up water in open cooling loop systems. Next step of treatment is softening. The water is used as boiler feed water. Final treatment step is membrane filtration in RO unit. The demineralized outlet water is used in production process.
Besides units, the complete water treatment solution contains storage tanks, pump stations, CIP unit for cleaning of membranes, a superior control system including remote surveillance and control of the entire plant.
