ZLD treatment of FGD waste water (Datang Group)
90% of coal-fired power plants will retrofit comprehensive FGD waste water treatment processes in future 3 years. The ZLD concept is a trend. CSRE was collaborated with Datang Group to investigate ZLD scale-up of FGD waste water. Application and development of traditional ZLD process are difficult due to high CapEx, high OpEx and unstable operation. CSRE MD, a cutting edge concentration technology, can concentrate 20 g/L of TDS to >150 g/L, which greatly reduces the feed volume of crystallization and flue gas spray-drying, thereby reducing ZLD cost.
