Who We Are

Optimum Water Technologies, a Singapore-based corporation, was formed in March 2009 to serve the growing need to provide safe, reliable, and cost effective systems for cooling water treatment and municipal water disinfection using on-site electrochlorination.

Power Generation



More than 70% of the earth’s surface is covered by seawater. This provides for an abundant supply of cooling water for coastal power stations, desalination plants and chemical plants. Yet, plant managers, engineers, and operators face the challenge of keeping seawater intake piping systems and heat transfer surfaces from being attacked by bio-species lingering in the seas. Macro-fouling (mussels, clams, oysters) and micro-fouling (bacteria, slime, algae) form deposits on condenser tubes, equipment, and piping systems result in unexpected plant shutdowns and losses in production.

Marine / Shipboard



The perpetual growth of sea life within a cooling system can cost even small vessels tens of thousands of dollars a year. By eliminating fouling, ships can save on fuel costs as well as make incalculable savings on maintenance. Electrochlorination offers a final and comprehensive solution to the problems of marine fouling throughout the shipboard cooling system.

Oil & Gas



Biological fouling is a frequent problem whenever seawater or freshwater is used as cooling or process water for processes such as re-gasification of liquefied natural gas (LNG), or in refineries, petrochemical plants, and offshore facilities. Optimum Water Technologies is experienced in the design and supply of tailor-made skid-mounted complete Seawater ElectroChlorination Units (Onsite Hypochlorite Generation Package) for safe, effective control of marine fouling in offshore facilities.
