ZLD Plant Manufacturer in India
Shachi Engineering is a leading ZLD plant manufacturer in India. ZLD plant or commonly known as zero liquid discharge plant is a typical wastewater treatment system that aims to eliminate liquid discharge of waste streams by recovering water and concentrating solid waste for disposal.
In a ZLD plant, multiple treatment processes such as reverse osmosis, evaporation, and crystallization are utilized to separate water from solids, resulting in a closed-loop water system where water is reused and solid waste is sent to a landfill or used for beneficial purposes.
The ZLD plant is beneficial for industries where water is scarce or costly and strict environmental regulations require minimal liquid discharge.
ZLD Plant offers 3 key benefits:
Minimize Waste
ZLD plant can help to fully minimize wastewater. ZLD is water treatment process where all the water is recovered from wastewater & leaving solid waste for final disposal.
Save Water
Treated water from the ZLD plant can be reused for other industrial processes including boiler feed & domestic application including gardening which need fresh water. This helps to save precious water.

Working Principle of ZLD Plant:
The ZLD plant typically involves several stages, including pre-treatment, evaporation, crystallization, and drying, to achieve complete removal of all contaminants and achieve zero liquid discharge.
The working principle involves the following steps:
- Pre-treatment: In this stage, the wastewater is screened to remove large particles and suspended solids. The pH level of the water is also adjusted, and chemical treatments are applied to remove dissolved solids and heavy metals.
- Evaporation: The pre-treated wastewater is then fed into an evaporator, where the water is heated and converted into steam. The steam is then condensed to recover the water, leaving behind a concentrated brine solution.
- Drying: The concentrated effluent from evaporator is fed to either spray dryer, agitated thin film dryer, centrifuge or crystallizer to finally convert slurry effluent into powder or solid form for final disposal. remaining liquid is fed into a spray dryer, where it is dried to produce a solid powder.
- Final solid disposal: The dried powder or solid is then collected and disposed of according to local regulations.
By following this process, ZLD plant can achieve zero liquid discharge, meaning that all wastewater is treated and reused, and there is no discharge of liquid waste into the environment. ZLD technology is increasingly being adopted by industries such as power generation, petrochemicals, and pharmaceuticals to address environmental concerns and reduce water consumption.
