Abstract

The aeration process involved compressed air and was aimed at improving the sedimentation of the suspended solids that form in the course of groundwater treatment. The experiments have revealed that the aeration of the backwash water from the filters used for iron and manganese removal from the groundwater being treated not only accelerated the precipitation of iron and manganese compounds but also increased the rate and efficiency of water clarification in the settling tanks. The use of compressed-air aeration seems to be recommendable in large and medium-sized groundwater treatment plants where the process can be applied to the pretreatment of backwash water. It also seems worthwhile to consider the possibility of recirculating (upon sludge removal) the clarified supernatant into the treatment train. Periodic aeration conducted prior to the sedimentation process will shorten the time of backwash water retention in the settling tanks and thus permit their dimensions to be reduced.

Project assumptions

The overall goal of the project is to develop an innovative multifactor mathematical model enabling monitoring of bath contamination used in the electropolishing process of austenitic stainless steels. This model will allow optimization and reduction of process costs and will have an impact on reducing environmental pollution during electrolytic polishing of austenitic stainless steels.

The final outcome of the project will consist in the development of a method of monitoring the gradual contamination of the electropolishing bath.

Team

The team deals with research in the field of electrochemistry, wastewater treatment, monitoring and optimization of processes in laboratory and industrial conditions. The diverse experience of individual members of the IonsMonit team is its strength.
