Upgrade aims to improve effluent quality from Class 2 to Class 1A standards
Tri-Tech Holding, Inc., a Chinese company that engineers, manages and monitors municipal sewer systems, natural waterways and other water resources, announced that it has received a $2 million build-transfer (BT) contract for a wastewater treatment plant upgrade in Xinle City, Hebei province. Tri-Tech will upgrade the plant and transfer ownership to Xinle City. The upgrade will aim to improve the effluent quality from Class 2 to Class 1A standards, as per the National Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant.
The Xinle wastewater treatment plant went into operation in 2003 and currently has a daily capacity of 40,000 metric tons. Reclaimed wastewater discharged from the treatment plant meets Class 2 standards. The upgrade work will aim to further decrease the pollution discharged from the plant.
The project aims to add an enhanced processing system, with a world-class process combination of a biological aerated filter (BAF), a rapid filter and chlorine dioxide disinfection. The enhanced processing system includes a new pumping station, disinfecting tank, chlorination processing system, forced draft blower, counter-washing pumping equipment and power supply system.
The contract covers detailed engineering and design, process equipment procurement, installation, commissioning and startup. The effluent discharged from the upgraded plant will meet Class 1A standards which is suitable for certain reuses, including roadway dust control, landscape irrigation and toilet flushing. Tri-Tech expects to complete construction by the end of February 2010.
"We are pleased to land this upgrade project in Xinle City using the BT model,” said Tri-Tech CEO Warren Zhao. “With the rapid economic growth in Xinle, the amount of industrial wastewater and municipal wastewater is increasing. However, wastewater treatment facilities have not kept pace with the growth. Inappropriately treated wastewater has severely polluted the surrounding canal and downstream rivers. The need to upgrade Xinle's existing wastewater treatment plant is urgent. The implementation of this project will reduce urban sewage pollution and improve Xinle city's ecological environment and water quality."
