IASON – Intelligent Activated Sludge Operated by Nanotechnology – Hydrogel Microcarriers in Wastewater Treatment

PVA-PAA hydrogel micro-carrier for the improvement of phase separation efficiency of biomass in wastewater treatment

“…Pollack Periodica 12, 2017, 2 microorganisms adhered to hydrogel surfaces on and within the gel structure) for pollutant removal [14].…”

“…Different inoculation procedures were tested in the preliminary stage of the research, and the colonization strategies of the hydrogel surface were optimized to achieve strong biofilm development. The inoculation procedure was evaluated using earlier experiences [14]; the duration of this phase was around 3 weeks. Temperature, pH, feed water composition, shearing forces, dissolved oxygen level were controlled in the experiment.…”

“…The efficiency of the biodegradation process, nitrification and denitrification rates was monitored. The shear forces were influenced by a central vertical shaft mixer with the suitable mixing intensity according to the earlier experiences [14].…”

“…Within the framework of the 3/081/2004 National Research, Development and Innovation Office (NKFP) research project at the Department of Sanitary and Environmental Engineering, Budapest University of Technology and Economics the use of artificial hydrogel micro-carriers were applied in laboratory scale wastewater treatment experiments aiming to improve the settling properties of the biomass [14], [15].…”
