  Biological carrier mediaFor waste water treatment  Carriers for suspended beds  The biological carrying media used in MBBR (Moving Bed Biofilm Reactor) are continuously in motion caused by air injection and recircula-ting water. The specific density of the carrier media can be adjusted from 0.95 to 1.15 g/cm 3 , depending on customers’ demand. However it has to be considered that the actual density of the carrying media will increase as the biofilm develops on the media surface. The advantage of the MBBR in comparison to the trickling filters and submerged fixed beds is that it maintains a thinner layer of biofilm on the carrier media which will allow higher specific surfaces.  Therefore it is permissible to have smaller reactor sizes which will turn into smaller investment costs while maintaining the necessary degradati-on of the organic load. The Bioflow 9  with its filigree structure shows a very high speci-fic surface area of 800 m 2  /m 3 . It is mostly used for waste water with low organic load. An example of this might be the waste water of fish farming.In case the organic load is still higher the Bioflow 40  will be the right choice. As its size and thus its weight per piece too is higher than that of the type 9 and 30 it was necessary to take care of the mechanical abrasion. Due to the drumlike shape the wear resistance is at a high level. Biological carrier mediaFor waste water treatment  An effective waste water treatment facility is an essential premise for ensuring a clean environment. One of the main process steps in a waste water treatment plant involves the degradation of organics by micro- or ganisms. Just as any living crea-ture these micro-organisms need oxygen to survive. This oxygen is most commonly inserted by air in  jection directly into the waste water. The process can be improved by adding solid surfaces to the water container. These surfaces give the micro-organisms a place to grow up and their residence time is lon-ger than the one of the water. RVT Process Equipment is delivering the optimum carriers for this application.No matter whether the process requires biological carrying media for trickling filters, random or sus-pended beds, all of the following requirements must be fulfilled: High specific surface area Good permeability of the waste water Optimum size and configuration in respect of price and durability Suitable to be cleaned by water flowing through Non toxic material to ensure the life of the micro-organisms  The Bioflow suspended bed filters from RVT Process Equipment at a glanceCarriers for trickling filters and submerged bed filters at a glanceCarriers for trickling filters and submerged fixed beds  These carriers are available both as structured blocks and as random carriers each of which ensuring the flow of water in all directions. When selecting a carrier next to the weight of itself the organic load must also be taken into calculation. For a high organic load a carrier with a more open structure might be ap propriate while for low organic loads a carrier with high surface area might be required.Random packingsStructured blocksMaterials: PE, black and natureMaterials: PE, black  The values indicated above apply for a ratio of diameter of vessel to carriers of D/d >/= 20.
