Effluent treatment plants (ETP) for industrial wastewater
Effluent treatment plants from Mai Fina for industrial wastewater: pH neutralization, oil and grease separation, DAF, chemical coagulation and flocculation, biological treatment, filtration and sludge dewatering by filter press, with RO and zero liquid discharge (ZLD) options for food and beverage, laundries, textile, chemical and automotive sites.
Treatment stages
- Equalization and pH neutralization with acid or caustic dosing.
- Oil and grease separation by oil-water separator or grease trap.
- DAF (dissolved air flotation) to remove fats, oils, grease and suspended solids.
- Chemical coagulation and flocculation to remove fine solids, colour and metals.
- Biological treatment for biodegradable organic load (BOD / COD).
- Filtration with sand, multimedia or activated carbon.
- Sludge dewatering by filter press.
RO and ZLD options
Treated effluent can be polished by RO for reuse in the process, and zero liquid discharge (ZLD) schemes can concentrate the RO reject so that no liquid leaves the site.
Sectors
- Food and beverage.
- Commercial laundries.
- Textile.
- Chemical.
- Automotive workshops and garages.
Compliance
Plants are designed to meet the applicable local authority limits for sewer discharge or reuse, with sampling points for regular testing.
Design data we need
Effluent flow and analysis (pH, COD, BOD, TSS, oil and grease and specific contaminants), production process, discharge or reuse route, available area and power supply.
