Tri-Tech will upgrade the plant and transfer ownership to Xinle City. The company claimed that the upgrade will improve the effluent quality from Class 2 to Class 1A standards as per the National Discharge Standard of Pollutants for Municipal Waste water Treatment Plant.
The Xinle waste water treatment plant went into operation in 2003 and has a daily capacity of 40,000 metric tons. Reclaimed waste water discharged from the treatment plant meets Class 2 standards. The upgrade work is expected to further decrease the pollution discharged from the plant.
The project will add an enhanced processing system, with process combination of biological aerated filter, a rapid filter and chlorine dioxide disinfection.
The enhanced processing system includes a new pumping station, a disinfecting tank, a chlorination processing system, a forced draft blower, counter-washing pumping equipment and a power supply system.
The contract covers detailed engineering and design, process equipment procurement, installation, commissioning and start-up.
The company said that 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. It expects to complete construction by the end of February 2010.
Warren Zhao, CEO of Tri-Tech, said: ”We are pleased to land this upgrade project in Xinle City using the BT model. With the rapid economic growth in Xinle, the amount of industrial waste water and municipal waste water is increasing. Inappropriately treated waste water has severely polluted the surrounding canal and downstream rivers.
“The implementation of this project will reduce urban sewage pollution and improve Xinle city’s ecological environment and water quality. ”
