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

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.

Multi-Effect Evaporation

MEE is a thermal desalination process that uses multiple stages of evaporation to concentrate wastewater. Each stage reuses heat from the previous stage, making it an energy-efficient method for reducing liquid discharge and recovering clean water.

Crystallisation

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.

Mechanical Vapor Recompression

MVR is an energy-efficient process that compresses vapor from evaporated wastewater, recycling its energy to evaporate more water. This reduces energy consumption and enhances water recovery, ideal for ZLD applications.
