What is a biofilm reactor?

The

biofilm reactor uses a colony of bacteria in laboratory and industrial processes to produce substances such as vinegar and acetic acid. It is also used to produce ethanol, lactic acid, butane, fumaric acid and jack acid. Biofilm is also used regularly for sewage treatment and bacteria can either absorb or decompose toxic substances in water. Different types of biofilm reactors include membrane, fluid bed, wrapped bed, air air and upflow anaerobic sludge. Individual cells must first be connected to the surface, either by an electric charge or a chemical attraction, or due to the concentration of nutrients near this surface. The cells must be irreversibly attached to the surface to form biofilm, which occurs when extracellular polymer (EPS) is produced. Biofilms evolve in the reactor when they are formed by water channelynts can achieve subsurface areas. Once nutrients are exhausted, cells that focus on EPS production, then break the matrix for foodLO and for escape. The membrane biofilm reactors in which the film grows on the gas transmission membrane is one type. The bacteria is used by a gas phase substrate, which can be hydrogen, oxygen or methane, ammonia or carbon dioxide. Contaminants such as nitrates, nitrites, chlorates, Bromat, Arsenante, Selenate and Chloroform can be reduced to harmless products during this process.

The media is mechanically mixed in a continuous mixed reactor of the tank, but the mixture cannot be upset if there is a support structure for the film. The reactor wrapped bed is first filled with support materials before the introduction of bacteria and is powered from bottom to top. Bacterial cells tend to grow rapidly in this type of biofilm reactor. The upper bed reactors are powered from above, but not every cell in the film gains nutrients. Other reactors include a fluid bed suitable for decomposing toxic phenolic chemiCali and air reactors that mix air from below with liquid in two tubes.

For water treatment, upflow anaerobic call blanket reactors are processed by waste water and industrial waste water. A biofilm reactor can also be used to decompose gases and odors. Overall, large volumes of water or fluid at high speeds can treat and create an effective industrial process.
