Bio filer applys in waste water treatment.it can promote sewage, oxygen, bio-film adequate mixing & stirring and keep bio-films

Suspension Bio-filter:

It is a new biofilm carrier which synthesis of Polymer. This carrier’s surface attaches number of hydrophilic group and Amino, carboxyl, Epoxy active group. Furthermore, it can form of ionic bonding or covalent bonding to fixed micro-organisms and enzymes on the carrier’s surface. Carrier’s surface not only forms Fungi, filamentous bacteria, Zoogloea, but also forms protozoa and metazoan. Finally, it forms stable food chain. Forming biofilm carrier’s density is close to water’s density. Big microbial load capacity, the volume load up to 8 Kg BOD5/m³.day, surface area is 23.3 m²/g. Because this structure is uniquely, it can promote sewage, oxygen, bio-film adequate mixing & stirring and keep bio-film’s good activity & gap variability
