Mbbr Bio Filter (Media)
Moving Bed Biofilm Reactor (MBBR) is an efficient biological treatment process, combines the Biofilm and fluidized bed. MBBR system consists of an aeration tank with special plastic carriers that provide a surface where a biofilm can grow.
MBBR filter media is a new biological suspension carrier which modified polymeric material with the promoted addition of bio enzyme, adaptable for all kinds of microorganism to grow and reproduction rapidly to dissolve organics in the water.
It process excellences of large specific surface, being easy to multiply biofilm, unease to fall off, high denitrification, good hydrophile, high biological activity and so on. It widely used in the MBBR sewage treatment biofilter, aquaculture farms, Koi Filter Media, etc.
