 Characteristics of the physical structure 

 Volcanic biological filter performance of 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. 

 Volcanic rocks in the sewage treatment industry is a water purification filter. Volcanic rock filter, light texture, chemical properties, the appropriate strength, surface roughness, voids developed and a reasonable distribution of wash-resistant, is not blocked, has a good physical, chemical and hydraulic characteristics, can be adapted to the requirements of the different sewage purification. Developed gap structure and rough surface makes it very suitable for microbial inoculation, acclimation, growth and reproduction. Therefore, the volcanic biological filter for BAF to use a biological filter. May be the treatment of organic industrial wastewater, municipal sewage, gray water of life, and micro-polluted source water. Also instead of quartz sand, anthracite filter media, activated carbon filter to filter media in water supply installations.
