A (near) Zero Discharge Project in the Steel Industry


The chemical water workshop of the power division of a chemical group in Shandong has introduced a total of 50 RO systems, with a daily water treatment capacity of 160,000 tons/day by 7206 RO membrane elements. It includes 26 VONTRON membrane element systems and 4596 VONTRON PURO-I anti-pollution RO membrane elements, with a daily water treatment capacity of 93,000 tons/day. the system has been running with good performance since its operation. 

 

After the zero discharge project was put into operation, it achieved zero discharge of wastewater in the chemical park, with the sodium chloride extracted as raw material for the chlor-alkali workshop, and mirabilite sold. This reaches the goals of resource utilization and zero discharge of wastewater, with great economic and environmental values.
