Wastewater from coal chemical and petrochemical production contains complex components, including organic matter, inorganic salts and heavy metals, posing significant treatment challenges. This wastewater primarily originates from processes such as coal gasification, oil refining and synthetic ammonia production. Leveraging its comprehensive membrane products (e.g., MBR, UF and RO membranes), Shuiyi provides integrated solutions covering wastewater treatment, reclaimed water reuse and (near) zero liquid discharge for the industry.
