Working and Importance of Zero Liquid Discharge Plant

A water treatment system is based on modern and advanced technology. It limits the pollutant of liquid at the end of the industrial process. This water filtration system purifies the wastewater and allows you to reuse water. The Zero Liquid Discharge Plant is based on the best and advances water purification techniques such as reverse osmosis, Ultrafiltration, evaporation, and fractional electro deionization. 

This water filtration plant is also known for the recovery of the maximum percentage of water from the wastewater. A right design ZLD Plant can:

·         Maintain and adjust the required volume of chemical in water.

·         Recover approximately 95% of liquid for the reuse.

·         Recover the useful byproducts from the wastewater.

The power industry, oil & gas, chemical, petrochemical, mining, and other sectors are generating wastewater at a large scale which must be managed. Thus, a Zero Liquid Discharge Plant Manufacturer designs a unit which can efficiently manage this wastewater.

What’s Included in the ZLD Unit?

Components Used in ZLD units are:

·         Classifier/Reactor is mainly used to precipitate out metals, hardness, and silica.

·      Chemical feed which is helpful to facilitate the precipitation, flocculation or coagulation of any metals & suspended solids.

·         To concentrate the secondary solids waste after the pretreatment is filter press.

·         Even a small amount of the suspended solids from the wastewater and prevent fouling, scaling, etc.

·         Reverse osmosis to remove the bulk of dissolved solids from the water in the primary phase of the concentration.

·         Brine concentrators to further concentrate the reject RO stream or reject form the electrodialysis to also reduce waste volume.

·         Evaporators were used for vaporizing access water in the final stage of waste concentration before crystallizer.

Depending upon your needs of RO plants, these standard components are usually adequate. If your plant still demands for the more customization than you can add on some additional features and technology.
