Biological media for water treatment,biocell, filter media Biological Filter media for water treatment,biocell, filter media 1General introductionThe suspension biological packing is called BIOCELL. It modified polymeric materials with the promoted additions of bio-enzyme, it improves the enzymatic catalysis, so it possess excellences of larger specific surface, being easy to multiply biofilm, difficult falling off, high denitrification, good hydrophile, high biological activity and so on.2Using scopeThe suspension biological packing widely uses in the sanitary sewage and industrial waste processing, is suitable especially for the excess load active sludge law transformation and the area limited newly built sewage factory.3The technical indices of the productAThe technical indices of BIOCELLspecification 10X7mm10X10mm12X12mmSpecific surface area>500m2/m3Packing rate70%Void volume>84.4%BOD5 Oxidized efficiency3.5kg BOD5/ (m3.d)Denitrification load20kgNox-N/(m3.d)Nitration load600gNox-N/(m3.d)BThe technical indices of new type BIOCELLspecification 25X9mmPacking rate15-60%Heaping number135256Nitration load675gNox-N/(m3.d)Specific surface area>500m2/m3NH4-N Elimination rate99%
