China supplier grey-white ceramsite filter media

Products Introduction
Ceramsite filter material is made of fly ash or clay as the main raw material, add special foam raw materials such as pore-forming agent, rare earth, after granulation forming, high temperature sintering, screened which a series of process. Appearance is reddish brown or gray, globular, the intensity is high, the granularity and porosity, high sewage capability is strong, hanging film rate, easy back flush, backwash low energy consumption, water consumption, less water head loss is small, aging membrane is easy to fall off, not easy jam, long operation period, the water rate is big. At present has been widely used in municipal sewage, industrial wastewater and sewage treatment, etc.
 

Products Applications

Ceramsite has excellent performance, such as low density, high cylinder pressure strength, high porosity, high softening coefficient, good frost resistance, resistance to JianJiLiao excellent reactivity, and so on.Especially because of the ceramsite density is small, internal porous, morphology, composition is uniform, and with a certain intensity and strong, thus has light weight, corrosion-resistant, antifreeze, and other multi-functional characteristics of seismic and well insulated. Using ceramsite these excellent performance, it can be widely used and building materials, gardening, food and beverage, fire-resistant insulation materials, chemical industry, petroleum and other departments.

Products Features 

◊ Round particles, uniform, surface roughness, micropore, internal pore developed, specific surface area is big, so biological bacterium adhesion ability, fast reproduction, hanging membrane with high efficiency, low temperature and low turbidity in addition to the effect of ammonia nitrogen under conditions reached domestic advanced level, long working period, cycle water rate is large, usually is 500-1000 m/m. 
◊The mass density of light, strength, and backwash low energy consumption, small head loss, clean material head loss is only 150 mm/m. 
◊ Sewage capability is strong, generally a 9-13 kg/m. 
◊ The filtration speed is high, generally for 15 to 20 m/h, up to 35 kg/m. 
◊The backwash water consumption is low, only about 30-40% of quartz filter material. 
◊Stable chemical performance, strong acid and alkali resistance, long service life.
