Supply Beijing volcanic filter manufacturers - Beijing volcanic filter model uses

Filter products of volcanic rocks: volcanic, biological filter, was born in the United States, China once rely on imports to achieve the biological biofilm, due to its high cost, the researchers developed a bio-ceramic to replace. Today, my company researchers after the study tour in the country to find suitable processing of the mineral deposits of volcanic rock filter, after beneficiation, crushing, sieving, grinding and processing of the granular media, the main ingredients of silicon, aluminum, dozens of minerals and trace elements, calcium, sodium, magnesium, titanium, manganese, iron, nickel, cobalt and molybdenum apparent irregular particles, the color red, black and brown, porous light weight, particle size according to different requirements. 
 Volcanic Media Product details: volcanic biological filter was first born in the United States, China once rely on imports to achieve the biological biofilm, due to its high cost, the researchers developed a bio-ceramic to replace. Today, my company researchers after the study tour in the country to find suitable processing of the mineral deposits of volcanic rock filter, after beneficiation, crushing, sieving, grinding and processing of the granular media, the main ingredients of silicon, aluminum, dozens of minerals and trace elements, calcium, sodium, magnesium, titanium, manganese, iron, nickel, cobalt and molybdenum apparent irregular particles, the color red, black and brown, porous light weight, particle size according to different requirements. Characteristics of the physical structure of the volcanic biological filter performance in the physical microstructure: surface rough microporous, these features particularly suitable for surface growth of microbes in their reproduction, the formation of biofilms. Volcanic media biological aerated filter can not only deal with municipal sewage, and biochemical organic industrial waste water, drainage of life, micro-polluted source water can also be replaced by quartz sand, activated carbon, anthracite as a filter media in water treatment , while the tail water in the secondary treatment process of sewage treatment plant has been advanced treatment, the treated effluent of reuse water standards for water reuse. The chemical structure characteristics of volcanic rock biological filter performance in the micro-chemical structure as follows: a microbial chemical stability: volcanic biological filter, corrosion resistant, inert biochemical reactions involved in biofilm in the environment. 2, the surface electrical properties and hydrophilic: volcanic biological filter surface with a positive charge, is conducive to microbial growth, hydrophilic, the amount of biofilm attached fast. 3, the effects of biofilm activity: as a biofilm carrier, volcanic biological filter fixed microorganisms harmless, non-inhibitory role of Practice has proved that does not affect the activity of microorganisms. Fourth, the hydraulic characteristics of volcanic biological filter performance of hydraulics: a porosity: inside and outside the average porosity of about 40% water resistance, while the comparable filter, filter the amount of required less, the same desired filtering objectives. , Specific surface area: a large surface area, the opening rate and inert contact with biofilm formation and growth of the microorganisms, more microbial biomass, microbial metabolic processes required for oxygen and nutrients and metabolic generation of waste mass transfer process. 3, the filter shape and water flow pattern: volcanic biological filter is not sharp granular, and the aperture most than ceramsite large, so use small flow resistance, saving energy consumption. 
 Volcanic bio-ceramic, volcanic bio-ceramic physical properties of porous: volcanic rocks is a natural cellular porous is the best environment for the growth of the floc is very suitable for microbial survival and reproduction. Appearance of the shape: the surface is rough, the speed of biofilm formation, microbial membrane backwash easy to fall off. Sharp granular, small flow resistance, clogging, water distribution uniform cloth gas; mechanical strength: the national quality inspection departments 7.25Mpa Practice has proved that you can stand the hydraulic shearing strength, life is far longer than other media. Density: Density is moderate, the backwash easy suspension without running material, can be energy saving.
