Earthlink’s Zero Liquid Discharge Treatment Guide

Zero Liquid Discharge (ZLD) is a wastewater treatment process that aims to eliminate all liquid discharge from industrial operations. The goal of ZLD is to conserve water resources by treating the wastewater generated in an industrial process to the point where it can be reused within the plant, or in some cases, converted into a solid material that can be disposed of. The process involves several stages, including treatment, evaporation, and crystallisation, to remove all water and produce a solid by-product. ZLD systems are commonly used in industries such as power generation, textiles, and petrochemical production where water is a limited resource and regulations require minimization of liquid discharge.

Opting for Earthlink technologies as a project contractor for your Zero Liquid Discharge solution can be a great decision as we have set forth a specialised team of professional sales engineers for this purpose. They are trained to conduct a thorough process of installation by following rituals like site analysis, requirements, procurement and supply of machineries, testing, and maintenance. This way nothing can come into way to successful installation and operation of your Zero Liquid Discharge.

Technologies used for Zero Liquid Discharge Solutions

SBR based treatment

Reverse Osmosis (RO)

RO is a filtration process that removes dissolved salts and other impurities from the wastewater, producing high-quality water suitable for reuse.

Multi Stage Flash Evaporation (MSF)

MSF is a combination of flash evaporation and RO that can achieve high levels of water recovery and minimise the volume of liquid discharge.

Electro-dialysis Reversal (EDR)

EDR is a technology used to remove dissolved salts from the wastewater, producing high-quality water suitable for reuse.


This involves converting dissolved salts and other impurities in the wastewater into solid crystals that can be easily removed and disposed of.

Membrane Bioreactors (MBR)

MBRs combine biological treatment with membrane filtration to produce high-quality water suitable for reuse.

1. What is Zero Liquid Discharge (ZLD)?

ZLD is a water treatment process that eliminates wastewater discharge by recovering and reusing all water while producing solid waste.

ZLD involves multiple treatment stages, including pretreatment, primary treatment, secondary treatment, and evaporation/crystallization to remove contaminants and evaporate water, leaving behind solid waste.

ZLD ensures environmental compliance by eliminating wastewater discharge, reduces freshwater usage, and offers potential revenue from selling solid waste byproducts.

ZLD systems can be costly to install and operate due to infrastructure and energy requirements, but long-term cost savings and potential revenue can make it cost-effective.

Yes, ZLD systems can be customized to meet the specific needs of different industries based on wastewater volume, composition, desired water quality, and available resources.
