keyword description:

this product is high quality clay as the main raw material, after drying, ingredients, pulverizing, into a ball, high temperature, screen classification and a series of process of granular materials. Its main composition is partial aluminum silicate, irregular appearance is nearly spherical particles, the surface is dark brown and microporous developed, particle size can be produce according to the different requirement. Biological ceramsite in terms of physical microstructure for rough surface pores, these characteristics make biology ceramsite is especially suitable for microbial growth and reproduction on its surface. Modern water treatment process make full use of these features, making it especially sewage water treatment, slightly polluted water biological pretreatment and ideal filter material feed water filtration technology, combined with its moderate density, high strength, friction resistance, stable chemical properties, not to release the toxic and harmful characteristics, water became the filter material of choice for water treatment engineering. Properties and parameters: the apparent density of 1. 6 - 1. 8g/cm³ Packing density 0. 75 - 0. 95g/cm³ Porosity & ge; 40% of specific surface area & ge; 4 m2 / g hydrochloric acid soluble rate < 2% friction loss rate < 2. > 4 2% compressive strength. 0 mpa calcination reduction < 0. 15% soluble substance does not contain harmful to human body trace element product advantages: more than 1, the surface pores, specific surface area is big, easy to hang membrane and the biomass is big, the NH3 - N, COD removal effect is good, sewage capability is strong, high treatment effluent water quality; 2, filter material layer uniform pore distribution, surface size for microbial growth well in hole and the big hole, overcome the caused by uneven distribution of filter material layer pore head loss is big, easy to jam, harden problems; 3, moderate density, uniform proportion, backwash time is short, use cycle is long, low energy consumption, it overcomes the defect of difficult to control and easy to run, province electricity industry; 4, with good particle size grading, pollutant carrying capacity is strong, filter material utilization rate is high, the head loss increase slowly, long running period, water rate; 5, do not contain any harmful substances on the human body and environment, strength, friction resistance, physics, chemistry stability is high, long life and now has been widely used in all kinds of industrial wastewater and sewage treatment. Application field; 1, industrial wastewater and drinking water treatment, industrial circulating water treatment; 2, dirty, Waste) Water advanced treatment and reuse, water treatment, swimming pool water treatment. 3, water supply in the micro pollutants ( Ammonia nitrogen) Processing, high purity preparation preprocessing system; 4, the biological aeration tank biological carrier; Web site
