A Zero Liquid Discharge (ZLD) system is an advanced water treatment process designed to eliminate liquid waste from industrial operations, resulting in zero discharge of wastewater into the environment. These cutting-edge plants use a series of advanced technologies to concentrate solid waste and recover and produce clean, reusable water. By implementing a ZLD system, industries can achieve full environmental compliance while significantly reducing their freshwater consumption.

Our ZLD systems are engineered to handle a wide range of industrial effluents and are available in a customizable capacity from 10 KLD to 100,000 KLD (kilo-liters per day) to meet the unique needs of your industry.

The ZLD Process: From Waste to Resource

The ZLD process is a multi-stage approach that ensures maximum water recovery and proper waste management. Our systems follow a logical progression:

• Filtration: This initial step involves advanced filtration techniques, such as reverse osmosis, to separate a large volume of clean water from the contaminated stream. This is a critical step in reducing the load on subsequent stages.

• Evaporation: The concentrated liquid (brine) that remains after filtration is then sent to an evaporator. This thermal process uses heat to vaporize the water, which is then condensed and returned as pure water for reuse.

• Crystallization: In the final stage, the remaining highly concentrated slurry is directed to a crystallizer. Here, any residual water is evaporated, causing the dissolved solids to crystallize. These solid crystals are then dewatered and safely disposed of.

This integrated process allows for a remarkable 90-95% water recovery, making our ZLD systems both environmentally friendly and economically sound.

Key Features of Our ZLD Plants

• Zero Liquid Discharge: Our systems ensure no liquid waste is released, protecting local ecosystems and meeting strict regulatory standards.

• Solid Waste Management: The concentrated solid waste is a dry, manageable product that can be safely disposed of or, in some cases, reused.

• Fully Automated Control: Each ZLD plant is equipped with a sophisticated PLC/SCADA system, providing full automation for efficient and reliable operation with minimal manual intervention.

Investing in a Bharat Ion Exchange ZLD system demonstrates a commitment to sustainable practices, enhances your company’s public image, and provides a long-term solution to water scarcity and disposal challenges.
