A Zero Liquid Discharge (ZLD) plant is a wastewater treatment system that recovers and reuses water, ensuring no discharge into the environment. Using filtration, evaporation, and crystallization, ZLD minimizes waste and conserves resources. It helps industries like power, textiles, and chemicals meet environmental regulations while promoting sustainability and reducing pollution and total water management by Hyperfilteration.<br><br><br><br><br><br><br><br><br>

Zero Liquid Discharge (ZLD) Plant by Hyperfilteration Our most advanced ZLD plant have more than 98% water recovery. We have successfully imbibed most updated technologies and come up with best results. If we see multiple industries like mining and petrochemicals so these types of industries are producing a lot of wastewater in the environment.
Introduction to ZLD Plant • Zero Liquid Discharge (ZLD) is an advanced wastewater treatment process that ensures no liquid waste leaves the facility. The goal is to recycle and reuse all water, leaving behind only solid waste. ZLD is crucial for industries dealing with high water consumption and strict environmental regulations.
Our ZLD Salient Features • • • • • • • • • • Highest recovery of 95-98%. Lowest operational cost 50-80RS/kl. Zero chemical sludge. Customized solutions. No space restriction. Exceptionally low capex. Minimum dying cost-salt recovery. Lowest stream & power consumption. Less maintenance & breakdown. Fully automated system in the world.
Importance of ZLD in Industrial Wastewater Treatment • Industries such as power plants, textile manufacturing, and chemical processing produce large volumes of wastewater. Without proper treatment, these pollutants can harm the environment. ZLD Plant helps industries manage water sustainability by treating and reusing wastewater effectively. • Biological tank consists bacteria which helps to reduce BOD and COD. It also maintain Dissolved Oxygen level in water. Bacteria helps to decompose all the organic material present in effluent. It requires proper aeration and food for proper growth of bacteria.
Key Components of a ZLD System • A ZLD Plant system typically consists of : • Pre-Treatment Units – Removes large contaminants • Evaporation Units – Concentrates wastewater • Crystallizers – Converts remaining liquids into solids • Recovery Systems – Extracts reusable water
Working Principle of ZLD Plants • The ZLD process includes : • Pre-Treatment: Removal of oils, solids, and organics. • Membrane Filtration: Reverse osmosis (RO) to concentrate wastewater. • Evaporation: Using heat to separate water from dissolved solids. • Crystallization: Converting remaining sludge into disposable solid waste. • Recovery & Reuse: Treated water is recycled back into industrial processes.
Technologies Used in ZLD Systems • Reverse Osmosis (RO) – Removes dissolved solids. • Multi-Effect Evaporation (MEE) – Uses multiple stages to maximize efficiency. • Mechanical Vapor Recompression (MVR) – Reduces energy consumption in evaporation. • Crystallization – Converts brine into solid waste.
Benefits of ZLD Plant • Environmental Protection: Eliminates wastewater discharge. • Water Conservation: Enables water recycling and reuse. • Regulatory Compliance: Meets strict environmental laws. • Resource Recovery: Extracts valuable by- products from waste streams.
ATFD (Agitated Thin Film Dryer) • For Reject more than 10000 litres per day, Our ATFD can easily handle and works on rotating blades technology for generating dry salt for disposal. This unit is manufactured in house and hence, low capital cost. • The pure brine solution obtained is either can be used directly in process via liquid dispensing system thus saving high cost of operation of drying the salt. Otherwise, the same converted into solid form i.e. used back in the process with the help of cooling crystallizer in case of glauber salt and MEE in case of Common Salt
