Large Size Waste Water Treatment Plants in China
HUBER Technology in Chongqing City
Chongqing, a city with about 7.5 mil people living in the urban area and a total of more than 32 mil inhabitants in the entire municipality. Thus, it is one of Chinas biggest cities. It is located at the upper stream of the Yangtze River directly above the Three Gorges Damn. Its water discharges are filling the newly erected reservoir. Chongqing government has realised that the water needs treatment in order to protect the Three Gorges Area. Therefore an exhaustive programme was established to clean the 2 mill m³/day. Three waste water treatment plants shall make the job: Jiguanshi and Taipingmen Pre-Treatment Stations and Tangjiatuo Waste Water Treatment Plant.
Over a number of years our sales and technology team of our JV Huadu-Huber Co. Ltd. has discussed with the customers, design institutes and contractors how to develop an adapted technological solution meeting the environmental requirements as well as handling the enormous quantity of the city’s waste water. Due to the outstanding performance of our ROTAMAT® Fine Screens in China as well as there easy handling and reliable operation, we have been able to supply the complete fine screening of all three Plants, including 6 units of the Ro 1 with an exceptional 3000 mm diameter at the Jiguanshi WWTP and not less impressive 12 units Ro 1 with a basket diameter of 2400 for the other two plants.
Now China is operating the largest number of our Huber Technology Super-Size Screens totalling to 40 units of screens with screening baskets 2 m and bigger. Beside the screens, we supplied our high efficient Grit Classifiers RoSF 3, the Washpress WAP for the core screens.
Installation and start up have been handled by the service team of our Joint Venture. Whereas it was first considered to invite German technicians to install especially the large Ro1-3000 screens, it turned out not to be necessary. The continuous training as well as the experience out of more than 120 installations of ROTAMAT® screens in China during the past 7 years show their fruits. Nevertheless, close contact between the service teams, technical experts, designers, and sales staff of our company in China and our headquarters are maintained for continuous experience exchange in both directions.
The concept of combining German engineering with localised support has helped us to develop the Chinese market and enable us to support in a qualified manner our Chinese customers. Thus, we where able to supply over 250 WWTP with more than 600 machines only in the municipal sector - not considering the numerous industrial applications. This has lead us in 2004 to increase our investment in China and thus our commitment to the Chinese market. We are proud of our team at Huadu-Huber Co. Ltd. in China!
