Neural-Adaptive Control of a Biological Wastewater Treatment Process. In a mixed liquor biological wastewater treatment process, it is very important to control the dissolved oxygen (DO) concentration. In this research work a robust control strategy is developed to Wastewater treatment by biological methods is becoming more important in the light of recovering value-added plant nutrients, heavy metals, biosolids, and bioenergy resources. Different types of Estimated Reading Time: 5 mins Standard wastewater treatment entails a combination of physical, chemical and biological processes and operations to remove contaminants (inorganic and organic) from the wastewater. In the treatment of wastewater, the suspended solids are removed by physical treatment, such as screening, grit removal, floatation and sedimentation

Biological treatment consists of using micro-organisms to break down compounds which it is not desirable to discharge into the natural environment, by a cycle of transformations that can be opened on to the outside environment when the products obtained are considered to be nonpolluting.

In the case of the biological treatment of urban wastewater, the process requires a mixed population of micro-organisms to be placed in contact with the pollutant elements of the water to be treated, i. suspended solids and soluble substances of organic or mineral origin.

In conventional biological wastewater treatment processes, this contact takes place in an aerated tank so as to encourage both the flocculation of the suspended solids with the micro-organisms, and the oxidation of soluble reducing substances. These so-called Activated Sludge procedures require prior treatment to remove sand and grease and allow for settling. Their operation relies above all on downstream clarification which clears the treated water and recycles the mixed liquors in the aerated tank see figure 1.
