Abstract

The study reported on in this paper was performed in the groundwater treatment plant Wasserwerk Langenberg (Germany) and included pilot plant investigations into the treatment of filter backwash water. To support sedimentation of suspended solids in the filter backwash water, use was made of Fe(III) chloride sulfate as a coagulant. The experiments were conducted to determine the influence of aeration and Fe(III) chloride sulfate on the composition of the filter backwash water after sedimentation in a settling tank over a period of 1 to 48 h. The results show that under these conditions filter backwash water should be treated using Fe(III) chloride sulfate doses ranging from 8 to 16gFeClSO(4)/m(3), with simultaneous 1-hour aeration upon coagulant addition. The study has produced the following finding: When use is made of Fe(III) chloride sulfate as coagulant, the backwash water streams from the rinsing of filter beds designed for iron and manganese removal from groundwater can be treated with such efficiency that permits their recirculation to the treatment train, or their reuse as technological water.

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.
