Ceramic sand filters

Product Description

PRODUCT NAME: Ceramic sand filters PACKAGING:demand according to the customer DESCRIPTION: Ceramic sand filters are doped with rare earth element and processed by mix shaping and ***** with traditional ands and coal filer material, ceramic sand filters have great advantages as follows: 1. Shaped in sphere , the ceramic filter Sand has a high void space, normally, its filter velocity is ****0m3/h, less lose water-head, and suitable to reduce the height of filter bed and cut down the electric power and constructionl expenses; 2. Uniform and regular in particle size, make it easy to be cleaned, the back-flush strength is ****0L/m2•s;It can save the back-flush water more than ****0%； 3. High surface area, large pore volume, the ceramic sand filters is of great amount of pollutant entrapment, up to ***0kg/m3, about 1.2 or 1.5 times that quartz sand filter of 7.**9kg/m3; 4. Great mechanical strength, less abrasion loss, and never be damaged, the ceramic sand filters can serve for a long life more than *5 years, is the 5 times or longer than that of quartz sand filters; 5. Corrpsion resistant, no run-off and no harmful substantce dissolved out, the ceramic sand filters can ensure the treated water in consistent quality without any secondary pollution may caused by the filter as quartz sand or coal filters itself.
