The automobile industry produces various types of wastewater containing oils, greases, heavy metals, and chemicals. To comply with environmental regulations and promote sustainability, several treatment systems are used:
Effluent Treatment Plant (ETP): Treats industrial wastewater using screening, sedimentation, biological treatment (aerobic/anaerobic), and disinfection to remove harmful substances before discharge or reuse.
Sewage Treatment Plant (STP): Handles domestic wastewater (from restrooms, kitchens, etc.) using similar processes to remove solids, organic matter, and pathogens.
Chemical Treatment: Uses coagulation, flocculation, and pH adjustment to remove dissolved contaminants and enhance treatment efficiency.
Water Recycling & Reuse: Treated wastewater is reused in non-potable applications like vehicle washing and irrigation, reducing freshwater consumption.
Zero Liquid Discharge (ZLD): Advanced treatment using reverse osmosis, evaporation, and crystallization to recover water and eliminate liquid waste.
Cooling Tower Water Treatment: Maintains cooling efficiency through chemical treatment, filtration, and microbial control.
Oil-Water Separation: Separates oils and greases from wastewater using gravity separation or coalescence for proper disposal or reuse.
These systems are tailored to the industry’s needs, helping manage water resources, reduce pollution, and support sustainable operations.
