Zero Liquid Discharge (ZLD) Systems are advanced wastewater treatment systems designed to eliminate all liquid waste by recovering and reusing almost 100% of the water. The process involves multiple stages such as filtration, reverse osmosis, evaporation, and crystallization, to separate water from waste. The treated water can be reused in industrial processes, while the remaining solid waste is reduced to a minimum. ZLD systems are used in industries like chemicals, textiles, power generation, and food processing, where water conservation and regulatory compliance are critical. They help companies reduce environmental impact, cut water procurement costs, and comply with stringent discharge regulations.
