Sewage refers to wastewater from homes, hospitals, offices, industries, public toilets, apartments, and other sources. The three main types of sewage are domestic sewage, industrial sewage, and storm sewage.

• Domestic Sewage: Also known as sanitary sewage, it carries used water from residences, hospitals, offices, public toilets, and apartments.
• Industrial Sewage: Consists of wastewater from manufacturing or chemical processes.
• Storm Sewage: Includes rainwater runoff from streets, often carrying harmful substances from roads and rooftops.

The disposal of untreated sewage causes environmental issues, including surface water pollution, groundwater contamination, and unpleasant odors. Sewage and wastewater may contain bacteria, fungi, parasites, and viruses, leading to various infections.

We provide comprehensive treatment solutions to remove dissolved and suspended pollutants, enabling the discharge of substantially clear water from sewage treatment plants (including preliminary, primary, secondary, and tertiary treatments) into oceans or rivers. Our treatment process includes pre-treatment (screening, grit removal, primary settling), biological treatment (aeration through the activated sludge process), secondary settling, filtration, and disinfection.

Generated sludge is dewatered and dried for use as manure or utilized in anaerobic digestion to produce biogas, which serves as an energy source. Additionally, treated water can be reused for gardening and toilet flushing.
