Biosorption system for tertiary wastewater treatment with in-line monitoring system

Development of wastewater treatment system, including equipment with biologically treated sorbent and in-line monitoring device for tertiary treatment of petrochemical wastewater. Optimisation of treatment technology on toxic compounds.

The treatment of ballast waters from ships and wastewater from oil refining and other petrochemical industries is based on a multiple stage treatment approach, consisting of physical-chemical and biological processes. Usually, the final step of the petrochemical wastewater treatment includes chemical coagulation, bioreactors, granulated activated carbon or sorption. These treatment stages are expensive and create problems such as fouling, backwashing, bacterial growth and problems with waste sludge disposal. The idea of this project is to develop a complex biosorption wastewater treatment system using microorganisms on solid phase medium. Microorganisms present in the biofilm on sorbent media oxidise the adsorbed pollutants and thus regenerate the sorbent surface. To be successful in this project, the development of a monitoring technology to control treatment efficiency especially for the most persistent and toxic organic compounds has to be developed. The final treatment system has to prove that the most problematic (important, toxic) compounds are treated and that the final effluent is cleaner also from a toxicity point of view. This has to be stressed since usually the treatment efficiency is based on the reduction of kg pollutant (avoiding the different toxic potential of treated and non-treated substances). PROJECT OBJECTIVES 1. OBJECTIVE for EXPOSMETER AB: to develop an in-line monitoring technology for measurement of efficiency of the biosorber treatment with modified SPMD for persistent and toxic organic compounds, which describes the cleaning efficiency and acts as a control measure. 2. OBJECTIVE for DINAITAS: to develop the hardware for the wastewater treatment system. To achieve a market validated and optimised product. 3. OBJECTIVE for KAUNAS UNIVERSITY OF TECHNOLOGY: to investigate different technological parameters and to understand the mechanisms acting during the treatment process. To describe the function of the bioreactor by means of different loads and types of wastewater. 4. OBJECTIVE for UMEAA UNIVERSITY: to analyse and understand the degradation process during wastewater treatment by analysing specific toxic compounds. 5. It is planned to patent the outcome of the project - an efficient wastewater treatment system. Keywords: wastewater, biosorption, monitoring.
