Applications
Biological filters are available in different types, including composite filters, 3D elastic filters, porous suspension ball filters, active biological filters and more. They are suitable for use in biochemical pools in sewage treatment plants.

Features
(1) High quality ethylene-propylene copolymer material is used, ensuring that long term immersion in waste water will not lead to degradation. This copolymer material is non-toxic.
(2) Large specific surface area, high biomass in unit volume.
(3) Microorganisms have a high activity: The microbial membranes growing on the surface of the filter will collide, and the aeration scouring causes the high activity of these microorganisms during the logarithmic growth period, thus providing a high processing efficiency.
