Wastewater Treatment System

Industries encounter major challenges in wastewater treatment, including managing large volumes, variable contaminant loads, and adhering to strict regulatory standards. The diverse range of pollutants from organic matter to hazardous substances – demands flexible and resilient treatment solutions that ensure efficiency while controlling costs and reducing environmental impact. To navigate these complexities, our wastewater treatment services offer a full spectrum approach, starting with pre-treatment for solids removal, followed by advanced biological processes to break down organics, and utilising innovative membrane filtration technologies to remove contaminants.

Feed Source Water: Industrial

Industrial wastewater refers to used water from manufacturing processes, chemical production, food processing, textile dyeing, pharmaceuticals, electronics, and more. It often contains:

High levels of organic matter (BOD/COD)
Suspended solids
Heavy metals (e.g., Cr, Cd, Pb)
Oil and grease
Toxic chemicals
Nutrients (N, P)
Acids or alkalis

Type	Description	Industries
Organic Wastewater	High in BOD/COD, biodegradable	Food, dairy, beverage, pulp & paper
Inorganic Wastewater	Contains salts, acids, bases	Metal plating, electroplating, chemical plants
Toxic Wastewater	Contains heavy metals, cyanide, VOCs	Textiles, pharmaceuticals, electronics
Oily Wastewater	Contains free and emulsified oils	Petrochemical, automotive, food
Thermal Wastewater	Elevated temperature	Power plants, refineries, steel mills
