PROJECT RATIONALE Initiated by the Eötvös József College (Baja, Hungary) and the Faculty of Sciences in Novi Sad, this research programme stemmed from the fact that the ground waters with high alkalinity and content of arsenic, boron, sodium and ammonia, are the main sources of drinking water for more than 1.8 million of people in the county of Csongrád and Bacs Kiskun (Hungary), and in Backa and Banat (Serbia). Ammonia and arsenic are the cause of problems on many drinking water treatment plants, which results in the fact that the majority of population in these areas drinks water in which the content of ammonia and arsenic is above the maximum allowable concentration for drinking water (0.5 mg/l and 10 mg/l, respectively). Precisely in Serbia, about 40% of the population (> 800,000 people) is supplied with drinking water containing more than 10mg As/l. Arsenic content in water varies from 50 to 100 mg/m 3, not to mention the cities where its content in drinking water ranges from 150 to 250 mg/m 3. Besides arsenic in groundwater used for municipal water supply in the areas of central and northern Banat, western Bačka and partly southern Bačka, water also contains natural organic matter in concentrations above 5 mg/l TOC, and even up to 13 mg/l TOC. Furthermore, it was confirmed that over 70 % of the drinking water contains ammonia above the maximum allowable value. PROJECT OVERVIEW Laboratory research conducted within the project, investigated different mechanisms and efficacy of certain technological processes for the reduction of arsenic and ammonia in water rich in natural organic matter. In addition, the composition of sludge generated during the treatment of water by various techniques (e.g. coagulation, flocculation) and the possibility to minimize its impact on the environment during further processing and disposal were also investigated. The research conducted will serve as a basis for determining the relevant environmental factors and the role of other pollutants in the process of arsenic and ammonia removal. The results were presented to the target groups (academic staff, government officials and experts in the field of water, local and regional self governing communities, etc.) with the aim to enable the people in the field of water supply to better understand and master the skills for developing the costeffective strategies for drinking water management, such as proper selection of the water treatment or optimization of the drinking water treatment plant. Through the Platform and transfer of knowledge, wider access to the following elements was provided: 1) Interdisciplinary research programs to address critical problems in the drinking water quality management in the region, including issues such as, for example, the choice of technology for the preparation of drinking water. 2) Training program for members of the Platform in the management of drinking water quality, in order to contribute to capacity building in the field of public education on the issues of environment and health that are related to water management.
3) Technical training and capacity building of the services to support utilities and other water experts, including government officials who have the responsibility of managing the safe drinking water. PROJECT GOALS The goal of the project is the implementation of the Platform for arsenic and ammonia removal, which will provide the necessary expertise and training to optimize the infrastructure development in the field of water supply in the region. Besides implementing the Platform, the project included a number of other activities to achieve the said goal: Establishment of a common database on water quality in the areas covered by the project; Renovation of the laboratory space and purchase of equipment (mobile pilot processing units for oxidation, coagulation and flocculation, membrane filtration); Developing processes for the removal of As and NH 3 ; Stabilization of sludge containing As; Examination of the impact of natural organic matter on the removal of As; Organization of conferences and workshops which serve for exchanging ideas and research results; as well as Other forms of dissemination (objectives and research results are published through various media). PROJECT IMPLEMENTATION Project objectives are realized through the activities covered by the specific work packages. 1. Joint implementation of the Platform A joint database on water quality in the areas covered by the project in Vojvodina and Hungary was created.
