Abstract:

Quality drinking water is a desire of the modern world and therefore the purpose of extensive research. Chlorination is the last step in the treatment of drinking water, leading to a disinfected, quality product. The positive effect of disinfection is unfortunately doubled by the formation of reaction by-products (DBPs) that are often carcinogenic and harmful. A solution for reducing the amount of DBP is represented by the decrease in the concentration of dissolved organic carbon, which leads to a lower concentration of chlorinated carcinogenic compounds in drinking water. The use of biofiltration before chlorination is a solution both for reducing the concentration of carcinogenic chlorinated compounds and for adsorption/absorption of pesticides from water and heavy metal ions, depending on the biofilter construction.

A major problem of biofilters is their sensitivity to environmental factors such as water temperature and composition, the slow rate of development of the bacterial biofilm that consumes dissolved organic compounds (COD), and the relatively low flow of purified water.

In this project, with a multidisciplinary team, young and experienced, we propose the synthesis of a new type of substrate for biofilters. It is based on natural materials such as shells that have a large specific surface area, modified with hydroxyapatite to increase the growth rate of the biofilm due to the phosphorus contribution. Due to the special two-dimensional shape of the shells, their superstructure at the microscopic level and the open pores, the constructed biofilters will have a low-pressure drop. Furthermore, the value of the empty bed contact time (EBCT) parameter will be strongly increased compared to the substrates currently used, increasing the efficiency of biofiltration.

Abstract:

The main aim of the present project is to establish a research-educational network for environmental protection and sustainable use of natural resources between the Politehnica University Timisoara (UPT) from Romania and Mining and Metallurgy Institute Bor (MMI Bor) from Serbia. The novelty resides in the fact that up to the present there is not such a structure in the region able to provide support to a multi-inter-trans disciplinary approach in the field of environmental protection. Considering that the research to date of each partner has been limited, the proposed partnership will broaden and complement the knowledge and experience of both partners and mostly will reduce fragmentation across the European research area. Therefore, this network may be taken as a model able to be transferred to similar situations. Moreover, it will remove the political, religious and economical barriers, so that in the future other institutions can adhere to it in order to apply to other common research projects within in the framework of projects promoted and financed by the European Union. To initiate the activities within the new-formed network, the cooperation between the partners (UPT and MMI Bor) will be focused on a major environmental cross-border issue concerning the treatment of the soil contaminated with heavy-metals due to mining activities. The cross-border cooperation within the IPA program is an example of good practice of connecting people and flow of information and knowledge. The partners recognize the need for joint efforts through the planned activities within the proposed project to achieve the set objective: forming of a network to improve the environment in the areas degraded by mining activities, with a tendency to get, based on joint scientific and professional work, positive results in terms of agricultural land remediation by applying phytoremediation, a cost-effective green technology. The project gets a new dimension when it is noted that it indirectly contributes to the preservation of the human population health, flora and fauna, as well as the preservation of endangered and rare species and habitats of the European Union and Serbia. The project is designed to raise awareness of inhabitants in the program area with regard to different issues of environmental pollution and ways to protect the environment. In order to achieve this goal within the project, workshops will be organized for training and education of the population, as well as for young researchers, students, bachelors and PhDs. The communication process is planned as an essential part of the proposed project. The public will be informed about EU policies and financial funds, intended for promotion of environmental protection and sustainable use of natural resources, through the knowledge-sharing activities by territorial networks, and promotion of the cross-border cooperation projects within the Interreg-IPA Cross-border Cooperation Romania-Serbia Programme.

Abstract:

For over two decades, environmental engineers have successfully commercialized anaerobic technology for the treatment of wastewater and solid wastes. In these processes, organic pollutants and wastes are converted into methane through a series of chain reactions by distinct groups of anaerobic microorganisms. Recently, emphasis started to shift to the development of novel anaerobic processes to convert organic pollutants into hydrogen, instead of methane.

Our consortium will apply unique microbiological and genomic approaches in order to increase the reliability and production efficiency of biohydrogen-generating wastewater treatment plants. Moreover, a novel logistics system model will be introduced to help the whole wastewater treatment workflow. The project adapts the most recent and high-tech genomic methods, the next-generation sequencing analysis, to the process of wastewater bioconversion. The main emphasis will be put on the proper digestion, hydrolysis of the substrates applied. This approach is completely justified by the nature of the wastewater fermentation being a complex, typical ecosystem with describable parameters. We have little knowledge about the dynamic metabolic processes, operation mechanisms taking place in such a system, we only know a portion of the elements constituting the system (bacterial strains), and we can draw conclusions by examining the features of the final products, biohydrogen and leftover sludge.

A mathematical model will be proposed in order to determine the optimal bacterial population composition, a microbiological wastewater monitoring system and a fuel cell system for direct biohydrogen use will be developed as the proposal’s end products.

Abstract:

The overall goal of the proposed project is to investigate a new approach of using the room temperature ionic liquid (RTIL) as extractants impregnated onto various solid supports in the adsorption process of radionuclides from waste aqueous solutions. The project has an interdisciplinary character presenting an integrated concept of waters depollution with radionuclides content. The use of ionic liquids (ILs) so called “green extractants”, instead of the volatile organic solvents as new separation media of metals from aqueous solutions is in agreement with the principle of the sustainable development and in full compatibility with the environment protection. Various ILs will be used, which will be impregnated onto various solid supports, and the resulted extractant impregnated materials (EIM) after characterization, will be used as adsorbent materials in the removal process of radionuclides from waste aqueous solutions. Using some solids supports impregnated with ILs as adsorbent materials is expected to achieve very good performance in the removal process of radionuclides from waste aqueous solutions because the adsorbent properties of the solid supports and the advantageous properties of ILs are combined, thus opening and establishing the new science based on both adsorption technology and ionic liquids. The benefit of the proposed research is provided by the scientific establishing and understanding of the mechanism of radionuclides adsorption from waste aqueous solutions
