Zero Liquid Discharge (ZLD) Solutions by Polaris for Advanced Sustainable Water Management

Water scarcity and stricter environmental regulations are pushing industries to adopt innovative solutions to manage wastewater. Zero Liquid Discharge (ZLD) is an advanced wastewater treatment approach designed to recover and reuse every drop of water while ensuring no liquid waste is discharged into the environment.

At Polaris, we specialize in developing customized ZLD systems tailored to meet the diverse needs of industries. With a focus on sustainability and efficiency, our ZLD solutions combine advanced technologies like membrane filtration, evaporation, crystallization, and thermal systems to achieve optimal water recovery and waste minimization.

  Polaris can deliver reliable and cost-effective ZLD systems for every industry, while meeting the businesses environmental and compliance goals.

What is Zero Liquid Discharge?

Zero Liquid Discharge (ZLD) is a wastewater treatment process designed to completely eliminate liquid waste discharge into the environment. It treats and recycles wastewater, recovering clean water for reuse and safely managing residual solids. While ZLD systems require investment, they offer long-term benefits such as reducing freshwater usage, complying with environmental regulations and recovering valuable resources. With government compliances and regulations getting stricter, it is important to implement ZLD in major industries today.

Benefits of Zero Liquid Discharge Systems

Adopting a ZLD system offers significant advantages to industries:

  • Maximized Water Reuse: This process helps achieve up to 95-99% water recovery, allowing maximum water reuse for industries. 
  • Environmental Compliance: It ensures adherence to strict wastewater discharge regulations and helps industries meet environmental compliance. 
  • Minimal Environmental Impact: The system prevents pollution by ensuring no untreated wastewater is released into the environment.
  • Cost-Effective Operations: By enabling efficient resource utilization, ZLD contributes to reducing long-term operational costs and improving sustainability.
  • Improved Brand Reputation: Adopting ZLD systems showcases your company’s commitment to sustainability and enhances brand reputation. 

How Polaris’s ZLD Systems Work?

Our ZLD systems are tailored to meet the specific needs of each facility. The process is influenced by factors such as waste volume, flow rate and contaminants. Here’s how it works:

  • Pretreatment: In this step, we use clarifiers, reactors, and filtration systems to remove suspended solids and oils. This protects downstream equipment from damage and ensures smooth operation.
  • Concentration: In this stage, processes like Reverse osmosis or nanofiltration remove the majority of dissolved solids, helping in reducing wastewater volume. 
  • Evaporation: In the next step, advanced multi-effect evaporators further concentrate the brine and separate it from reusable water. 
  • Crystallization: In the last stage, Crystallizers boil off the remaining liquid, leaving solid waste for safe disposal and maximizing water recovery.
