Evaporator/ZLD System
Evaporators and ZLD systems are essential technologies for wastewater treatment, aimed at achieving sustainability and regulatory compliance by minimizing water discharge and maximizing resource recovery.
Components of a ZLD System
1. Pre-Treatment: Removes large particles, oils, and organics.
Includes filtration, chemical dosing, or sedimentation.
2. Concentration Stage: Uses evaporators or Reverse Osmosis (RO) systems to reduce water content in the effluent.
3. Crystallizers: Converts concentrated brine into solid salts for disposal.
4. Condensate Recovery: Recycles clean water from evaporation for reuse in processes.
Applications
1. Power Plants: Treat cooling tower blowdown to recover water and reduce waste.
2. Chemical and Petrochemical Industries: Manage complex effluents containing salts, acids, and heavy metals.
3. Textile and Dyeing Units: Recycle water from dyeing processes, reducing freshwater consumption.
4. Food and Beverage Industry: Handle wastewater with organic residues, ensuring hygiene and regulatory compliance.
5. Pharmaceuticals: Treat high-salinity and chemically contaminated effluents.
6. Mining and Metallurgy: Process tailings and recover valuable minerals from effluent streams.
