Siemens designed, engineered, manufactured, supplied and constructed both the wastewater and water plants, which began operations in February 2011.
The wastewater treatment plant is treating about 5,500 cubic meters/day of process wastewater from the Estate’s chemical manufacturing facilities, to meet discharge limits.
The wastewater treatment plant of the Asia Industrial Estate in Rayong includes biological treatment using jet aeration, clarifiers, sand filters, four activated carbon filters and a reactivated carbon storage vessel.
The company said the carbon must be changed out when its capacity to adsorb the targeted organics has been reached.
When this happens, the carbon is considered spent, and must be removed from the vessels and replaced with fresh carbon media.
