Why Zld is important ?
The ZLD system has attracted attention due to water scarcity, strict environmental rules and the need for permanent industrial practices. The major reasons are ZLD important :
. Water resources protection
. Reduction in environmental pollution
. Compliance with environmental laws
. Recovery of valuable by-products from waste sections
ZLD Ecnologies used in ZLD
. Membrane Technologies: Reverse Osmoses (RO), Nanophilation (NF), Ultrafiltration (UF)
. Thermal procedures: multi-affect evaporation (mee), mechanical vapor revaluation (MVR)
. Crystallizer: Forced circulation and vacuum crystallizer
. Salty concentrations: Reduce the quantity of waste before crystallization These techniques are combined and optimized based on specific waste water structure.
Benefits of ZLD
• Environmental Protection: Eliminates wastewater discharge into ecosystems.
• Water Reuse: Recovered water can be reused, reducing dependency on freshwater.
• Resource Recovery: Valuable salts and chemicals can be reclaimed.
• Regulatory Compliance: Helps industries meet strict discharge standards.
Case Studies of Zero Liquid Discharge
• Textile Industry in India: Adoption of ZLD in Tamil Nadu has helped in managing dye effluents effectively.
• Power Plants in China: Implementation of MVR and crystallizers has reduced water consumption.
• Oil Refineries in the Middle East: High-recovery ZLD systems treat highsalinity brines for reuse.
