Activated sludge process
Activated sludge treatment plant
At ser.eco. we design and build activated sludge treatment plants. The process replicates a natural biological mechanism and combined with several stages, or with other filtration methods, it offers excellent treatment, even for the most difficult effluent. The active sludge process is the most widely used in traditional treatment systems, there are multiple applications of this treatment system in the civil and industrial sector.
Operation of an activated sludge treatment plant
The process created in an activated sludge treatment plant harnesses the metabolic action of the biomass (microorganisms) that utilises the organic substances and oxygen in the effluent for its action and reproduction. As a result, colonies of bacteria are formed into flocs that are eliminated in the subsequent settling stage. If anoxic or anaerobic reactors are used, the flocs are kept in suspension with mixers, in aerated reactors this is achieved using air insufflation.
