Share Article

Siemens Ltd. Thailand was awarded a double-digit million dollar (U.S.) contract by MTP HPPO Manufacturing Company Limited, a joint venture between The Dow Chemical Company (“Dow”) and the Siam Cement Group (SCG), for water treatment and waste water treatment plants. The plants will support a grass roots Joint Venture complex being built by Dow, SCG and Solvay at the Asia Industrial Estate in Rayong, Thailand. Siemens will design, engineer, manufacture, supply, construct and provide commissioning support for the water and waste water treatment plants, which are expected to be completed and operating by mid to late 2010 respectively.

The Joint Venture complex at the Asia Industrial Estate will include the complete infrastructure required for industrial operations, including utilities, water and wastewater treatment and sludge handling. Located on Thailand’s south coast, the estate will meet environmental standards required by its proximity to residential communities, pristine beaches and resorts. The complex will include hydrogen peroxide, propylene oxide, propylene glycol, specialty elastomers, and hydrogen SMR (Steam Methane Reforming) manufacturing plants.

Siemens will supply sand filters, reverse osmosis and ion exchange equipment to the water treatment plant, which will deliver 1600 m3/hour of utility water, 200 m3/h of demineralized water and 60 m3/h of potable water to the facility.

Siemens will provide the wastewater treatment facility with a reliable and innovative biological wastewater treatment design consisting of jet aeration, high performance Tow-Bro clarifiers, sand filters and activated carbon filters. The plant will treat up to 200 m3/hr of process wastewater to meet discharge limits.

This latest award for Siemens is the result of more than eight months of work by the Siemens’ proposal teams in Thailand and Singapore and Dow to determine the client’s requirements. The client chose Siemens for its collaborative approach and focus on value engineering to meet the client’s techno-commercial needs, as well as Siemens’ technical expertise and full service support capabilities in Thailand.
