Polyurethanebio-fillers
Product Introduction：
Polyurethane porous gel carrier is made of polyurethane and other polymer composite, referred to as PPC carrier. This carrier is an aerobic biological carrier that provides space for microorganisms to grow. PPC carrier has a unique wall structure, increasing the specific surface area of the carrier, while increasing the carrier wear resistance, longer life expectancy. The carrier has a hydrophilic gel, good elasticity and easy attachment of the microorganism to the membrane, meanwhile, the higher porosity ensures the parenteral mass transfer inside and outside the carrier and the growth environ - ment of the microorganism is excellent.Polyurethanebio-fillers
Technical Principle
Different microorganisms (from bacteria to ciliates to rotifers) concen - trate on the surface of the carrier to form biofilms. In aerobic system, the carrier is kept in a fluidized state by aeration. The pollutants are gathered on the biofilm through this movement and then degraded by microorganisms.Polyurethanebio-fillers Polyurethanebio-fillers

Aquasust hydrophilic Polyurethane bio-fillers is a new type of biological filler modified and synthesized by polymer polyurethane material. The combination of macropore and micropore provides the basic conditions for the macropore to maintain stable gas, liquid and solid state. Micropores are used for adsorption and fixation of microorganisms. There are hydrophilic active groups such as amino, carboxyl, and epoxy group in the micropores that allowed HPU MBBR Biomedia to absorb water, expand and settle rapidly as well as allowed the microorganisms and biological enzymes adsorbed and fixed on the HPU MBBR Biomedia rapidly at the same time. The density of immobilized microorganism HPU biomedia is greater than the density of water, making it to form subsidence rapidly in the water with a large microbial load and a larger volume load than the surface area. Due to the structure characteristics of HPU biomedia, it allowed the sewage, air and biofilm to get mixed contact exchange, and made it possible for a large number of bacteria to sit in the carrier rapidly and maintain great activity and void variability. In addition, in the process of operation, the gases collide with each other driven by the three-dimensional flowing sewage, and are cut into smaller bubbles by the HPU biomedia in a peristatic state, which increases the utilization rate of oxygen and reduces the aeration amount. Therefore,HPU biomedia, as a new type of biological media, has the characteristics of strong bubble cutting ability, large space volume utilization rate, and non-blind area.
