Ceramic filter material made of high quality clay, clay, glue solvents, such as grinding, sieving, calcination and processed, with a hard surface, internal micro-porous, high porosity. Aerobic activated sludge as vaccinations, two weeks to reach the water treatment biological aeration filter.

Ceramsite filter material is the main ingredient for aluminum silicate, dark brown or grey-brown, grain size according to different requirements. Lightweight ceramic with high performance film in terms of physical microstructure characterized by rough microporous, these features make high efficient membrane biological ceramsite particularly suitable for growth of microorganisms on the surface, to breed. Modern water treatment process takes full advantage of these features, making it especially the sewage water treatment, biological pretreatment of micro-polluted source water and the ideal filter water filter technology, coupled with its density is moderate, high strength, abrasion, stable physical and chemical properties, characteristics not poisonous and harmful materials released into the water, becoming the preferred filter material for water treatment works. Filter) ceramsite filter material in the production process is: raw materials, auxiliary materials formula → → drying → grinding ¡ú grain cooling → drying → firing → → → → → packaging storage of measurement of screening of BAF process is the core of filter) ceramsite filter material. Excellent filter material with a surface easily bio-film, micro-holes, large surface area for microbial rapid proliferation. Due to the bulk density is moderate, easy to backwash and aeration, it tube high pressure (4.5Mpa), can withstand high water impact loads for a long time. The stable effluent, reducing operating costs.

Adsorption rate of 100 (%) 2800 resistance pressure (kgf)
Density of 3 (g/cm3) 55 porosity (%)
Wear rate (3 hardness 6

Chemical constituents of Silicon oxide, aluminium oxide, calcium oxide, iron oxide, magnesium oxide soluble in hydrochloric acid rate of ≤ 2 (%)

Main features:

1. particle, uniform, rough surface, microporous, well-developed porosity, specific surface area, so bacterial adhesion ability, breed fast film high ammonia nitrogen removal under low temperature and low turbidity conditions reach the domestic advanced level, long work cycle, water cycle, usually 500-1000m/m.

2. bulk specific gravity of light, strength, to backwash low energy consumption, small head loss, clean the head loss is only 150mm/m.

3. pollution-cutting ability, General 9-13kg/m.

4. high filtration rate, usually 15-20m/h, up to a maximum of 35kg/m.

5. back-flushing water consumption low, only Quartz filter 30–40%.

6. stable chemical properties, acid and alkali-resistant performance, long service life.

Grain: 5-20mm, 25mm is the biggest.
