The biological process for the treatment of wastewater in which organic matters are degraded by bacterial activity, comprises performing an extensive or intensive biological treatment of wastewater slightly or strongly filled with pollution, reposing the little deep water for inherent self-purification on...
The present invention refers to a wastewater biological treatment process using one or more stages combined in series, each one including one chamber for effluent aeration (4) with biomass in local suspension where secondary treatment takes place, followed by a chamber (5) with immobilized zeolites...
It is the process of removing pollutants and contaminants from water before it is released back into the environment. One of the most effective methods of wastewater treatment is biological treatment. This method involves the use of microorganisms to break down pollutants and contaminants in the ...
Thus, the biological treatment needs to accomplish a 6-fold decrease in BOD. Principle: Simple bacteria (cells) eat the organic material present in the wastewater. Through their metabolism, the organic material is transformed into cellular mass, which is no longer in solution but can be ...
The most persistent and hazardous pollutants come from industrial and agricultural activities; therefore, effective treatment of this wastewater prior to discharge into the natural environment is the solution. Advanced oxidation processes (AOPs) have caused increased interest due to their ability to ...
Application of microbial degradation and removal of undesirable constituents in industrial and municipal wastes is not a new concept. It is commonly used process for general wastewater treatment activities and has been for many years. As the awareness of chemical contamination of the environment, much...

In subject area:Chemical Engineering A biological wastewater treatment process in which flocs of variety of microorganisms are allowed to break down organic compounds and nutrients in an aerobic, anoxic, or anaerobic environment. From:Water Reclamation and Sustainability,2014 ...
The basic function of wastewater treatment is to speed up the natural processes by which water is purified. There are two basic stages in the treatment of wastes, primary and secondary, which are outlined here. In the primary stage, solids are allowed to settle and removed fromwastewater. The...
Method and system for treatment of water and wastewater Biological processes for treating wastewater include the conventional activated sludge process, which has continuous flow in and out of each treatment cell, and the sequencing batch reactor (SBR) process, which operates on a batch fill a... ...
