Siemens to Supply Carbon Replacements to Thai Plant

Siemens is to provide bulk carbon media replacement and reactivation services for the wastewater treatment plant at Asia Industrial Estate in Rayong, Thailand.

The wastewater treatment plant, which was designed, engineered, manufactured, supplied and constructed by Siemens, treats up to 5,500m³ per day of process wastewater from the estate’s chemical manufacturing facilities.

The plant’s biological treatment facility uses jet aeration, clarifiers, sand filters, four activated carbon filters and a reactivated carbon storage vessel.

The carbon vessels, which hold about 18t of carbon for treating up to 200m³ per hour of process wastewater, must be changed when their capacity to absorb the targeted organics has been reached.

Siemens will provide change-out and replacement services when the carbon vessels reach capacity.
