Zero Liquid Discharge (ZLD) system

A ZLD system is a comprehensive treatment process designed to eliminate the discharge of any liquid effluent from industrial processes. This advanced system utilizes various technologies like evaporation, concentration, crystallization, and drying to treat the effluent and recover valuable resources such as clean water and usable salts. The treated water can then be reused within the industrial process, while the recovered salts can be sold as a by-product or utilized as raw material in other industries.

The ZLD System Explained: A Multi-Stage Treatment Approach

ZLD systems typically involve a series of treatment stages, including:

• Pre-treatment: This initial stage removes large particles and contaminants from the effluent through processes like screening, settling, or filtration. This step safeguards downstream equipment from damage and enhances the overall efficiency of the treatment process.
• Primary Treatment: The primary treatment stage focuses on eliminating oil and grease from the effluent using skimming or air flotation techniques. This prevents these contaminants from fouling downstream equipment.
• Secondary Treatment: Here, the focus is on removing dissolved solids and organic matter from the effluent. Technologies like reverse osmosis or ultrafiltration are employed in this stage to significantly reduce the effluent’s Total Dissolved Solids (TDS) and Chemical Oxygen Demand (COD).
• Tertiary Treatment: The heart of the ZLD system, this stage removes any remaining contaminants using evaporation, crystallization, and drying processes:
  
  • Evaporation: The effluent is fed into an evaporator unit where high temperatures are used to evaporate the water content. The evaporated water condenses and is collected as clean distillate, while the concentrated effluent is sent for further processing.
  • Crystallization: The concentrated effluent then enters a crystallization unit where the remaining salts are precipitated as crystals. These crystals are collected and can be sold as a by-product or used as raw material in other industries.
