Water & wastewater treatment systems manufacturers and suppliers in Singapore

A global water-infrastructure EPC and design engineer; designer of Singapore's Sembcorp Changi NEWater Plant and a long-standing contractor on PUB-programme reclamation and desalination works.

A membrane-based water and wastewater treatment group using MBR built on Memstar hollow-fibre membrane, with a portfolio of municipal and industrial treatment plants across China and Singapore delivered on BOT/TOT models. Formerly United Envirotech.

Designs, fabricates, installs and commissions engineered water-purification and wastewater-treatment systems using membrane and ion-exchange technologies, with municipal and power-sector projects and O&M and resin-regeneration services.

An ASX-listed maker of ultrafiltration PES hollow-fibre membranes with graphene oxide, and PVDF-AG membranes, from a Singapore base at Tuas South, targeting industrial water and wastewater and decentralised treatment.

Manufactures anti-fouling PVDF hollow-fibre ultrafiltration membranes (NSF-certified) and engineers UF and brackish-water RO systems for seawater desalination, municipal drinking water, wastewater recycling and industrial process water. A First Line group company.

An SGX-listed asset manager and operator whose infrastructure arm spans three clean-energy capabilities. In solar, Keppel Renewable Energy develops solar and cross-border clean-power, progressing an Indonesia-to-Singapore electricity import licence. In water, Keppel Seghers built and operates the 137,000 m3/day Keppel Marina East Desalination Plant and delivered the 162,800 m3/day Ulu Pandan NEWater upgrade. In waste, it runs the ~2,310 t/day Senoko and ~800 t/day Keppel Seghers Tuas waste-to-energy plants, together treating close to half of Singapore's incinerable waste.

The Singapore industrial water-treatment arm of the Kurita group, serving refinery and petrochemical, power and semiconductor customers with boiler, cooling and wastewater treatment chemicals, RO and membrane solutions, ultrapure water and ion-exchange systems, plus plant build and monitoring. Operations at Joo Koon with a Johor site.

Supplies ceramic flat-sheet membranes and complete industrial-wastewater treatment systems, covering design, manufacture, construction and O&M. Its ceramic-membrane technology differentiates it from the PVDF hollow-fibre cohort.

Developed a thermal membrane-distillation zero-liquid-discharge (ZLD) system built on a highly hydrophobic hollow-fibre membrane for high-saline effluent from electroplating, semiconductor, chemical, pharma and oil-and-gas processes. Technology partnership with Syensqo (Solvay).

A Singapore-based manufacturer of PVDF hollow-fibre membranes for MBR and water-treatment use, and the membrane-production arm of CITIC Envirotech. One of the indigenous membrane makers.

An SGX-listed Singapore-headquartered operator of one of Indonesia's largest municipal water-treatment portfolios, with total treatment capacity of roughly 14,000 litres/second serving over three million residents in Greater Jakarta.

Built Singapore's first 3D-printing plant for water-filtration membranes, producing nanofibre membranes for water and wastewater treatment and MBR applications. One of the indigenous membrane makers.

An SGX-listed energy and urban-solutions group, and Singapore's largest solar owner-operator — over 535 MWp locally across rooftop, ground-mount and floating, including the 60 MWp Tengeh Reservoir floating farm and the won 86 MWp Pandan Reservoir tender, with SolarNova tranches awarded. In water, it operates the Sembcorp NEWater Plant at Changi, Singapore's fifth and largest (~228,000 m3/day), and multiple energy-efficient MBR industrial-wastewater and reclamation plants including on Jurong Island.
