Project operation effect
The desalted water system of the power plant is the largest desalted water treatment system in the whole northwest, with a treatment water volume of 1800 tons per hour. The system has been operated by our company since it was put into operation in 2013. After years of mature operation and management experience and excellent pharmaceutical quality, our company has continuously and stably produced up to standard water for the whole magnesium Industrial Park for many years, ensuring the safe, stable, long, full and excellent operation of the production plant. After nearly ten years of operation, ultrafiltration, reverse osmosis and EDI equipment are basically not replaced, which saves a lot of membrane replacement and daily operation and maintenance costs for the workshop.
