Zero Liquid Discharge (ZLD) Overview

    Zero liquid discharge is a process that is beneficial to industrial and municipal organizations as well as the environment because it saves money and no effluent, or discharge, is left over.

    The Chemplast unit has multiple waste streams, the primary source being the Caustic soda and PVC monomer plants. 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.

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).

  • Industrial Process Water

    Water treatment is used to optimize most water-based industrial processes, such as heating, cooling, processing, cleaning, and rinsing so that operating costs and risks are reduced. Poor water treatment lets water interact with the surfaces of pipes and vessels which contain it.

  • Desalination

    Saltwater is desalinated to produce water suitable for human consumption or irrigation. One by-product of desalination is salt. Desalination is used on many seagoing ships and submarines.
