Volcanic biological filter 

 The About volcanic filter products: volcanic rock filter was first born in the United States, once rely on imports to 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 for processing the biological filter of volcanic mineral beneficiation, crushing, screening, grinding and other processing of the granular media, the main ingredients of silicon, aluminum dozens of minerals and trace elements including calcium, sodium, magnesium, titanium, manganese, iron, nickel, cobalt and molybdenum, the apparent irregular particles, the color red, black and brown, porous light, particle size different requirements of production. 
 The physical characteristics of the volcanic rock filter: 1, appearance: sharp granular flow resistance is small, easy to plug water distribution uniform cloth gas; rough surface, the speed of biofilm formation, microbial membrane backwash easy to fall off. 2, porous: volcanic rocks is a natural cellular porous, bacteria micelles is a good growing environment. Mechanical strength: by the national quality inspection departments 5.08Mpa Practice has proved that you can stand the hydraulic shearing strength, life is much longer other media. Density: moderate density, backwash easy suspension without running material, can be energy saving. 
 Characteristics of the physical structure of volcanic rock filter (high-hanging film light filter) performance in the physical microstructure: surface rough microporous, these features are particularly suitable for the microorganisms on the surface growth, reproduction, 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. Fourth, the chemical structural features 
 Volcanic biological filter performance in the micro-chemical structure: 
 A microbial chemical stability: volcanic biological filter anti-corrosion, with 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. 5, hydraulics characteristics of volcanic biological filter in the hydraulic performance of: 
 Porosity: the inside and outside the average porosity of about 40%, resistance to water, while the comparable filter, the required filter less the same to achieve the 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 filter was first used in foreign countries, China had imported the volcanic filter as water treatment biological carrier. In the country to find raw materials for processing volcanic filter. Processed by the selected processing, bio-activation processes, the apparent irregular particles, the color is dark brown. ???? Porous lightweight particle size depending on the requirements of production. The biological filter, dealing with the biodegradability of organic industrial waste, municipal sewage, gray water of life, and micro-polluted source water. 9, quality assurance and its economy???? Product quality, I get the Government's strong support and assistance, on a new modern production line, annual production capacity of 10 tons, from the production process in terms of more than ceramsite procedures are simple, in the filter media particle size than ceramsite easy to control, so convenient for the needs of different users, and low production costs, more than any other media economy, and quality performance is superior; we strive to product quality strictly checks, and cost savings. Let volcanic filter play a role in the cause of environmental protection. ???? Note: "Malan River sewage treatment plant in the country the first to use the largest Biological Aerated Filter and volcanic biological filter, the packing of the enterprise.
