Ceramic sand filter is our production and development of an advanced water treatment media, spherical particles, uniform size, appearance of reddish-brown, the surface porous, the internal pore networks criss-cross, has a strong adsorption, the Chongqing Architecture University of the test, the filtration rate in the same conditions, the ceramic water yield than the quartz sand filter to more than double compared with repeated washing water savings of 30-40% quartz sand, with a filtration rate is fast, long cycle and so on.
