Shale biological filter is a novel biofilm carrier filler. Using shale or clay, adding the active agent, the high temperature calcination, finishing. Shale filter has good physical, chemical and hydraulic characteristics, surface area, porosity, adsorption interception ability. How the surface of the hole, multi-angular, rough and easy to hang the film, and a certain mechanical strength, is an ideal microorganism carrier. Attached growth of microorganisms is very beneficial, soilless cultivation of flowers, potted bonsai cultivation, energy-saving materials and construction, it has light volume, high pressure to engage in, insulation, frost, shock, radiation, etc.. Shale biological filter is applied to urban and industrial water treatment, is also widely used in metallurgy, petroleum, chemical, textile and other industrial wastewater biochemical oil, iron, manganese and filtration treatment, it not only can be used as various Common types of fast filter, valveless, siphon filter, rinse cover mobile filter, pressure filter of media, but also a variety of efficient purifier, water purifier packing small towns. Features: 1, lightweight, loose small capacity, large leather area, high porosity, with sufficient mechanical strength. 2, does not contain harmful to human health and prevent harmful impurities in industrial production, good chemical stability. 3, small clean filter head loss, form factor, strong adsorption ability, suitable hydraulic roughness values.
