What is a Zero Liquid Discharge System?

Zero Liquid Discharge (ZLD) ensures that no wastewater is released into the environment. Unlike normal plants, where wastewater is treated and discharged, in ZLD, the discharge isn’t allowed.
The wastewater is first collected in tanks where oil, solids, heavy dirt, and impurities are removed. This step is basic but essential. If this is not done correctly, the system fails later. After that, the water is sent to membrane systems, such as RO, for purification. Here, most of the usable water is recovered. Although the water is not suitable for drinking, it is suitable for industrial use.
The rest of the water released from the RO is filthy, with high salt and TDS levels. Since it can’t be treated further, it is sent to evaporators.
In the evaporator, water is boiled and separated. What remains is a thick slurry. This slurry then goes to a crystalliser. Salts are formed and taken out as solid waste.
In this setup, only solid waste is discharged, not liquid; hence, the name suggests Zero Liquid Discharge.
