This latest project is a follow up to an initial US$40 million build-transfer contract awarded to
Tri-Tech in 2010.
The initial project will allow the Ordos facility to process 96 000 cubic meters of water per day, via traditional flocculation, sedimentation and conventional filtration, and then go through the ultrafiltration and nanofiltration treatment process.
The expansion phase is designed to allow processing of 104 000 cubic meters per day treated via the traditional flocculation, sedimentation and conventional filtration process. Approximately 50% of the treated water will undergo ultrafiltration and nanofiltration treatment processes. The rest of the treated water will bypass ultrafiltration and nanofiltration. Tri-Tech will provide design optimisation, procurement, installation, startup and commissioning, owner’s personnel training, operation and maintenance manual preparation of water treatment plant, and other services as needed.
Following the completion of the initial and expansion phases, the Ordos plant will be the world’s largest treatment facility that uses ultra filtration and nanofiltration membrane technology, capable of producing 148 000 cubic meters ultrafiltered and nanofiltered water per day.
The expansion will be carried out by Ordos Anguo Tri-Tech Investment Co Ltd, the project company jointly owned by Tri-Tech (Beijing) Co Ltd and Beijing Anguo Water Treatment Automation Engineering Technology Co Ltd.
“Most of China’s water treatment still uses coagulation, sedimentation, filtration and disinfection. This traditional process is unable to process water at the rate demanded by China’s population, which struggles with water quality issues such as disease-causing microorganisms, algae and algal toxins, turbidity, disinfection byproducts and unstable water quality,” said Tri-Tech co-president Phil Fan. “There is an urgent need for conventional water plants to be upgraded and to enhance wastewater treatment and reduce pollutant emissions, gradually reaching new drinking water standards in the country.
