MM Aqua Technologies offers Fill Media, Type FB10. This is for industrial and municipal sewage treatment industries. This type of media provides an excellent solution to all the prime requirements of a biological fill system and in particular, provides a large effective surface area with minimum tendency to plugging. This is a high efficiency and high "in-service" reliability media. The characteristics of cross-fluted fill media ensure a very high biological degrading performance. This structure produces a very large, fully usable surface area for contact between the biomass, the air and the water flowing through it. The fill serves as a carrying medium for the biomass and favours a uniform growth of biological slime due to its regular structure. The biological purification stage is normally followed by a mechanical separation of solids stage. FS41.50 tube settler is employed to enlarge the effective settling area can considerably enhance the efficiency of settling process. The water quality is improved enabling larger volumes to be economically treated.
