Bio Filter Hydrophilic Sponge

Hydrophilic sedimentation type polyurethane biological filler (referred to as PPC filler) is a new type of biological filler modified and synthesized by polymer polyurethane material. The macropores and micropores in the PPC packing are combined, and the macropores maintain good contact conditions of gas, liquid and solid. Micropores are used to adsorb and immobilize microorganisms. The micropores contain hydrophilic active groups such as amino groups, carboxyl groups, and epoxy groups. PPC fillers can quickly absorb water and swell to sink water. At the same time, microorganisms and biological enzymes can be quickly adsorbed and immobilized on PPC. on the filler. The density of the filler after immobilizing the microorganisms is greater than that of water, so that the filler settles rapidly in the water body, the microorganism load is large, the volume load is large, and the specific surface area is large. Due to its structural characteristics, PPC fillers can mix and contact sewage, air and biofilms, and a large number of biological strains can quickly settle in the microbial carrier, maintaining good activity and void variability, and during operation. Driven by the three-dimensional flow of sewage, the gas collides with each other and is continuously cut into smaller bubbles by the PPC filler in a peristaltic state, which increases the utilization rate of oxygen and reduces the amount of aeration. Therefore, it has the characteristics of strong ability to cut bubbles, large space volume utilization, no dead zone, etc. PPC filler is the replacement product of current biological filler
