Common Effluent Treatment Plant (CETP)
CETPs are built to treat wastewater from multiple small and medium industries in the same area or cluster. They help industries that can’t afford individual treatment systems. But CETPs often face serious challenges due to the variety and complexity of wastewater coming from different industries.
The effluent quality keeps changing every day, depending on the industries — like textile, pharma, chemical, metal, and more. Because of this, it's tough to treat all types of wastewater with a single setup. Traditional CETPs need large space, multiple chemical and biological processes, and still struggle to meet discharge norms.
Industry Challenges in other ZLD systems
Mixed Pollutants
Mixed effluent with different types of pollutants — like dyes, solvents, acids, oils, and metals.
Variable Loads
High and fluctuating TDS, COD, and BOD levels.
Performance Issues
Frequent issues in performance due to varying wastewater quality.
Large Footprint
Large area required for conventional CETPs.
High Costs
High operating cost due to energy, chemicals, and manpower.
ZLD Challenges
Difficult to achieve Zero Liquid Discharge (ZLD) with traditional systems.
