Volcanic rocks in the filter material

Volcanic rocks in the filter material is introduced:

Volcanic rocks in the filter material originally applied in foreign countries, our country has to import volcanic liao as water treatment of biological carrier. Our company produces the volcanic rocks in the filter material of raw materials. After separation, crushing, screening, grinding and a series of process of granular filter material, its main ingredients for silicon, aluminum, calcium, sodium, magnesium, titanium, manganese, iron, nickel, cobalt and molybdenum dozens of kinds of minerals and trace elements, such as apparent as irregular particles, color is red, dark brown, porous light, particularly suitable for microbial growth, reproduction, on the surface to form a biofilm. The particle size can be ordered according to the different production. The use of the biological filter material, biochemical organic industrial wastewater treatment, municipal sewage, life drain, and slightly polluted source water.

Volcanic rocks in the filter material is to realize the aeration biological filter sewage treatment technology of key material, this product is compared with the traditional biological ceramsite, not only has a light texture, good chemical stability, intensity the advantage such as suitable for rough surface, easy to hang the membrane, and the pore developed, reasonable distribution, very suitable for the inoculation, domestication and breeding of microorganism growth. Resistance to flush, non-clogging, has the good physical, chemical and hydraulic characteristics, can be adapted to the not with the requirement of sewage purification. Because the ceramsite is greater than surface area, can accumulate a high concentration of microbial quantity, high concentration of microorganisms increased aeration biological filter volume load, high removal rate. Unit volume efficiency of sewage treatment 5 to 7 times higher than that of conventional filter material, can meet the environmental emission standards.

Volcanic rocks in the filter material that aeration biological filter can not only deal with municipal wastewater, and a biochemical organic industrial wastewater, complex drainage, slightly polluted source water of life, etc., can also be used in water treatment to replace ceramsite, quartz sand, activated carbon, anthracite and other used as filter medium, at the same time also can have after sewage treatment plant secondary treatment process of tail water do deep processing, after the recycle water for water standard for water reuse. This product by the "ministry of construction of water treatment filter material quality supervision inspection center" detection, good indicators, reliable in performance.

Volcanic rocks in the filter material physical properties:

1, appearance shape: without sharp granular, small flow resistance, not easy jam, cloth water gas evenly; Rough surface, hang film speed, backwash when microbial membrane is not easy to fall off.

2, porous: volcanic rocks is a natural honeycomb porous, is the growth of zoogloea best environment.

3, mechanical strength, by the national quality inspection department is 5.08 Mpa, the practice proved can efficiently in different intensity of hydraulic shearing action, service life is much longer other filter material.

4, density, medium density, backwash easily suspended and not run material, saving energy and reducing consumption.
