What is a Zero Liquid Discharge?
Zero Liquid Discharge (ZLD) is an ultimate cutting-edge wastewater treatment process developed to completely eliminate all liquid discharge from a system. The goal of a zero liquid discharge system is to reduce the volume of wastewater that requires further treatment, economically process wastewater and produce a clean stream suitable for reuse.
Zero liquid discharge (ZLD) is used to concentrate RO/NF reject in industrial wastewater plants. Most of the water in the concentrate is recovered as product by separating the salt from the water. ZLD systems include reverse osmosis, thermal evaporators, crystallizers, brine concentrators and spray dryers. The condensate from evaporator also returned to the process.
In order to prevent pollution of River water and ground water the ZLD system mandatory for all the highly polluting industries including:
- Textile Industries
- Dyeing Industries
- Bleaching Industries
- Tanneries Industries
which uses considerable amount of salt in the process and consumes huge quantity of water. The ZLD system ensures recovery of water & salt from the waste water thus preventing pollution of River / ground water.
