Established in 1992 as a high-tech consortium specializing in scientific and technical research in water treatment, membrane technology and products, and the development, production, marketing and servicing of household water purification equipment. It is responsible for the torching programme, the “fifteenth” science and technology project, and for participating in and carrying out scientific and research tasks such as the 863 programme and the 11th five-year science and technology programme (water specialized). In the “fifteen” science and technology campaign, the successful development of the “pvc alloyed plumbing superfilms” (pvc-c-c-c-c-c-c-c-c-c-c-c-c-c-c-c-c-c-c-c-c-c-c-c-c-c-c-c-c-c-c-c-c-c-c-c-c-c-c-c-c-c-c-c-c-c-c-c-c-c-c-c-c-c-c-c-c-c-c-c-c-c-c-c-c-c-c-c-c-c-c-c-c-c-c-c-c-c-c-c-c-c-c-c-c-c-c-c-c-c-c-c-c-c-c-c-c-c-c-c-c-c-c-c-c-c-c-c-c-c-c- the results were awarded first prizes in the “certificate of priority new products”, “scientific and technological prize” in henan province and “scientific and technological award” in the china multimedia industry association, at an advanced level in the world. It has one of the world's largest superfiltration production sites in the sea mouth, producing 3 million square metres of pvc and pvdf cavity superfilms annually, and is at the forefront of the world. In suzhou, a large production base for ultra-filtration equipment has been established, with approximately 500,000 units of annual column and curtain ultra-filtration components, small-scale ultra-filtration equipment and household and commercial water purification units. Upgrading ultrafiltration components are used for municipal water treatment, operating energy consumption is comparable to traditional processes, intelligent choice is lower than traditional processes, 75 per cent compared to traditional processes, and water saving is between 3-5 per cent, but indicators such as the complete filtration of bacterial viruses, microorganisms and turbidity are better than united states and european community standards and become the core technology for “third generation water treatment”. It's one of the largest separation plants in the world. – taiwan’s 300 million cubic metres of daily water purification water supply plant, with the full use of elevated superfilms, marks the rise in the world’s leading industry in this area, which, as of october 2009, had been operating successfully for three years, becoming an example of how high-pollution, high-change water quality treatments could be addressed in the global municipal water supply sector. In november 2009, the southern peri-urban plant at shandong battalion, using the vertical leachate pvc alloy superfiltration technology, became a large membrane water plant with advanced domestic overfiltration techniques。
