The National Water Technology Platform leaded by BME has the primary aim to develop a long-term strategic research agenda for the urban water management sector. As the result of the Platform’s activity in 2009, Strategic Research Agenda was prepared. This paper presents its findings concerning the public works in water sector. Based on the SWOT analysis of this sector, problems and future challenges have been assessed of the drinking water supply and sewer networks. The Agenda evaluated the Hungarian R&D&I activity in the field of public works of urban water management made projections on the time horizon beyond 2035.
In biological wastewater treatment technologies the majority of the systems are based on activated sludge technology. In these systems the population structure and dynamics of the activated sludge microbial community is largely governed by indirect regulatory mechanisms, such as the aerated/non-aerated reactors, reactor configurations and sludge recycling ratios. The development of polymer gels provides opportunities to fabricate microscopic size bioreactors for wastewater treatment. PVA-PAS (polyvinyl alcohol- polyacrylic acid copolymer) polymers proved to be effective. The primary object of our analyses is to study the nanotechnologically constructed micro-reactors in MBR systems. In this paper a case study is presented where the operational problems of artificial flocs in an MBR system were investigated.
Assessing wetland state through monitoring is the condition of their protection. Wetland resources support healthy environments; communities, and economies, effective watershed management should include conservation and restoration of wetlands and their functions. This study focuses on the development and implementation of a monitoring system for one of the greatest floodplain area: Gemenc-Béda-Karapancsa in accordance with the Water Framework Directive requirements which measures the environmental effects of changing environmental conditions in the Danube’s main river channel due to certain rehabilitation works, via monitoring of surface and groundwater hydrology, water and sediment chemistry and ecological state of the aquatic ecosystem elements.
