Industrial effluents contain hazardous chemicals, heavy metals, suspended solids, and high COD/BOD levels that must be treated before discharge. AES WaterTech provides complete ETP solutions including primary, secondary, and tertiary treatment stages, designed to meet CPCB/SPCB discharge norms.
Our ETPs are customized based on industrial effluent characterization and can include ZLD (Zero Liquid Discharge) configurations for industries with stringent discharge restrictions.
Treatment Stages
- Primary: Screening, equalization, pH correction, coagulation-flocculation
- Secondary: Biological treatment – aerobic/anaerobic reactors
- Tertiary: Sand filtration, activated carbon, Fenton oxidation
- ZLD: Multiple-effect evaporator, agitated thin film dryer
- Sludge handling: filter press, sludge drying beds
- Online monitoring with effluent meters and data loggers
