First,Honeycomb Ceramics or corrugated plate filler: this sort of filler is usually made of glass fiber reinforced vinyl or plastic (polyethylene, polystyrene and polypropylene, etc.) along with other materials. Its advantages are light weight, high porosity, high strength, and great anti-corrosion functionality. The downsides are: poor control of microbial growth and shedding, and difficulty in obtaining uniform flow rates. Click our site for information of Honeycomb Ceramics. Honeycomb Ceramics
Second,granular filler: granular filler is your earliest filler, made from inorganic ceramsite or quartz sand. The key benefits of this filler would be the surface, the easy attachment of microorganisms, along with the capability to trap suspended solids; however its resistance and ease of plugging are his important defects!
Third, Spherical Lightweight Ceramsite: Spherical lightweight ceramsite generally uses clay as its raw material, also adds proper chemical raw materials because expansion agent and can be fired at high temperatures. Compared with traditional fillers, the benefits of spherical lightweight ceramsite are: high durability, large porosity, large specific surface area, acceptable density, very decent chemical stability, and powerful biological adhesion; downsides are: high energy consumption, The groundwork price is high. So much in China, the spherical lightweight aerated biological filter along with its mixture procedure have been extensively utilized in sewage treatment, printing and dyeing wastewater treatment, and beer wastewater treatment. In several years of practice, it's achieved outstanding consequences. Fourth, irregular porous filler: the previous fillers are RaschingRing, PallRing, etc.; the present filler includes Hacketten and multipurpose light-weight ball, etc., the creation of materials like tower internals, ceramics, graphite, plastics and alloys. The main advantage is that the construction is easy and economical; yet, the uneven distribution of fluid is his fault.
