Filamentous bacteria are important in the activated sludge process as they contribute to proper solids-liquid separation in the secondary clarifier by providing a skeletal matrix for the formation of compact flocs. Morphological and molecular techniques were applied over a one-year period to comprehensive...

At the end of the third stage of the process, the COD remained high and stable above 2300 mg O2/L. It was of interest to gather data for the parameters of the model process, which are directly related to the structural and functional characteristics of the activated sludge. These ...
The basic process of sludge utilization predominantly involves spreading it over the surface of the soil to fertilize it or improve its properties. Final disposal of sewage sludge is used in the following areas: • In agriculture, for growing crops, • For the reclamation of land, including ...
However, the activated sludge method of sewage treatment also has a big disadvantage, that is, a large amount of sludge will be produced in the process of sewage treatment in sewage plants. The problem of sludge treatment has become an important issue in the sewage treatment process [1]. ...

The biomass physical properties influence the milling process. The chemical activation process can be achieved in several ways, as outlined below: The chemical activation method is accomplished by the infusion, mixing and permeation of a solution, usually a dehydrating chemical with the ability to ...
