In the field of wastewater reuse and zero discharge, the company's integrated "ultrafiltration + reverse osmosis" dual-membrane system can produce high-quality reclaimed water, which is widely used for make-up water in circulating cooling systems and process water in production. For higher standards of "zero discharge" requirements, the company has mastered the technology chain of "hardness and silica removal + COD removal + high-efficiency reverse osmosis + MVR/multi-effect evaporation crystallization", achieving wastewater concentration and salt crystallization separation.
