Zero Liquid Discharge Plant (ZLD)

Zero Liquid Discharge Plant (ZLD Plant)

A Zero Liquid Discharge (ZLD) Plant is an advanced wastewater treatment system that ensures no liquid waste exits the facility. It treats industrial effluents through processes like reverse osmosis, evaporation, and crystallization, recovering clean water and isolating solid waste or concentrated brine.

ZLD systems are especially valuable in regions facing water scarcity or where environmental compliance is strict. By recycling water and eliminating discharge, they support sustainable industrial operations and reduce environmental harm.

For industries seeking complete water recovery, ZLD technology represents a significant step toward eco-conscious and future-ready manufacturing.

Why Konark WaterDoc by Konark Group?

Konark WaterDoc, part of the Konark Group, delivers high-performance ZLD solutions designed to meet complex industrial needs. With years of experience and a strong focus on sustainability, we engineer systems that exceed compliance requirements and align with long-term environmental goals.

Our Edge in ZLD Technology

• >> Smart, Advanced Solutions: Our ZLD systems are built using modern technologies for maximum recovery and minimal waste.
• >> Regulatory Compliance: We ensure that all systems meet local and national environmental discharge norms.
• >> Tailored for Industry Needs: Each plant is customized to suit specific industrial wastewater profiles.
• >> Reliable Quality: Built with robust materials and engineering expertise for dependable, long-term operation.

ZLD Plant: Core Process Stages

• ZLD plants follow a multi-stage process to treat and recover water:
• >> Primary Treatment: Removes suspended solids, oil, and coarse debris to prepare effluent for advanced stages.
• >> Advanced Purification: Reverse osmosis (RO) and other filtration methods eliminate dissolved salts and fine impurities.
• >> Evaporation: The remaining liquid is evaporated to extract more usable water and concentrate the brine.
• >> Crystallization: Solid waste is separated from brine in the final stage, leaving clean, reusable water.
• This process enables up to 95–98% water recovery, ensuring minimal waste and environmental compliance.

Our Approach to ZLD Projects

At Konark WaterDoc, we begin with a detailed evaluation of your wastewater type, industry standards, and compliance needs. We then design a cost-effective and efficient system that aligns with both your operational goals and sustainability targets.

We carefully plan system capacity and scalability, ensuring it handles both current and future loads. Close collaboration with your team throughout design and implementation guarantees a solution that fits seamlessly into your operations.

ZLD Technologies: We Offer

• ZLD systems combine multiple technologies based on project requirements:
• >> Mechanical Vapor Compression (MVC): Reclaims water by condensing vapor from evaporated effluent.
• >> Thermal Evaporation: Uses heat to separate water from dissolved solids.
• >> Forward Osmosis (FO): Draws water across membranes, leaving brine for further treatment.
• >> Membrane Distillation (MD): Vaporizes water through a membrane, leaving contaminants behind.
• >> Crystallization: Converts concentrated salts into solids for safe disposal or reuse.
• By integrating these technologies, Konark WaterDoc ensures zero liquid discharge, maximum water recovery, and reliable performance for industries committed to sustainability.
