Dongying volcanics factory direct - Contact: Manager Li _FXT: _18301509601 _ Business QQ_631979131__ Company Website _www.bjgkhxt.com / factory always adhere to: customer trust is to survive on the basis of the high quality service our customers return We warmly welcome customers at home and abroad, and water treatment experts to visit the guide, www.bjklhxt.com/ discuss cooperation! The volcanic rocks biological filter: the first born in the United States, China, once rely on imports to implement bio-linked to the membrane technology, due to its high cost, the researchers developed a bio-ceramic to replace. Today, my company researchers Through investigation and research in the country to find deposits of volcanic rock filter suitable for processing, beneficiation, crushing, screening, grinding series of process from the processing of granular filter media, the main ingredients of silicon, aluminum, dozens of minerals and trace elements of calcium, sodium, magnesium, titanium, manganese, iron, nickel, cobalt and molybdenum, and the apparent irregular particles, red, black and brown in color, different from the porous lightweight, particle size under requirements.

Second, the characteristics of the physical structure of volcanic rocks of biological filter performance in physical microstructure: the surface roughness microporous, these features are particularly suitable for the micro-organisms in the surface growth, reproduction, formation of biofilms. Volcanic rocks Biological Aerated Filter filter can handle not only the municipal sewage, and biodegradability of organic industrial wastewater, drainage, micro-polluted source water, but also can replace the quartz sand to the water treatment, such as activated carbon, anthracite is used as a filter media while on the the tail water after secondary treatment process sewage treatment plant has been advanced treatment of recycled water standards for water reuse its treated effluent. Chemical structure characteristics of volcanic rocks biological filter performance in chemical microstructure: microbial chemical stability: Volcanic biological filter anti-corrosion, inert biochemical reactions involved in biofilm environment. 2, the electrical properties of surface and the hydrophilic: volcanic surface of the biological filter with a positive charge, is conducive to microbial solid growth, hydrophilicity, the attached biofilm amount and speed. 3, the impact of biofilm activity: as a biofilm carrier, volcanic biological filter fixed microorganisms harmless, the inhibitory effect, proved not affect the activity of the microorganisms.
