Case Studies

Wastewater treatment (Design & Build)

Oil & Gas: Wastewater treatment with Plasma-Nano Bubbles AOP

Design and build a Wastewater Treatment plant with AOP technology to meet stringent environmental discharge limits for highly toxic pollutants such as effluent Phenols <0.2ppm, Sulphide <0.2ppm, COD<100ppm in a sensitive petrochemical environment where safety compliance is of utmost importance.

Anaerobic Digestor Plant (Retrofitting)

Renewable Energy: Anaerobic Digestor Plant

Achieved a 2.2MW of daily electricity generation (~30,000 m³/day Biogas). 60% of treated effluent is used for on-site recycling, and the sludge after digestion is further processed by composting to produce fertiliser.

Biogas Plant Water Treatment (Design & Build)

Oil & Gas: Slop and Sludge Wastewater Treatment and Reuse

To design and build a wastewater treatment plant that can handle 250 m3/d of wastewater using Advanced Oxidation Process. The treated wastewater is recycled and reused for on-site process applications.
Sewage Treatment Plant (Upgrading)

Commercial Building: Upgrading of existing STP of Large Dormitory

Design and retrofit/upgrade the onsite containerised sewerage treatment plant for a large coastal dormitory housing 12,500 foreign workers to a facility with the capacity to treat 3,750m3/day of wastewater to meet NEA discharge to watercourse requirements. This containerised STP must be designed and built to last for another 10 years until the estimated completion of Changi Terminal 5.
