Zero Liquid Discharge (ZLD)
The combined wastewater is heavy in contaminants like oil & grease, volatile organic compounds, and has a relatively high COD and TDS of about 10,000 mg/l. The water is potentially bio-active and also has a high fouling and scaling tendency. As an environmentally conscious corporate entity, Chemplast’s primary intent was to treat the rejects from the Reverse Osmosis (RO) system by Evaporation/Crystallization so as to achieve Zero Liquid Discharge (ZLD).
