Denitryfikacja wody pitnej w bioreaktorze membranowym
Committee on Biotechnology PAS ; Institute of Bioorganic Chemistry PAS
The aim of this study was to define denitrification kinetics using bacteria Paracoccus denitrijicans cultivated in membrane bioreactor equipped with microfilter module with ceramic cartridge with cut off 0,45 pm. Water used in experiments was loaded with very strong nitrateconcentration reaching up to 6,0 g NO3 /L. Methanol was used as carbon source and was addedin an amount 30% higher than the one calculated stoichiometrically. The pH value of water wasautomatically adjusted to 7,0. As experimental variables the following parameters were tested:i) supplementation of water with some nutrients, including monopotassium phosphate and microelements: molybdenum, copper, ferric and magnesium ions, variable initial cell biomass concentration, ii) different cultivation methods: stationary batch fermentation in glass flasks andcontinuous fermentation in membrane bioreactor with cell recycling, iii) procedure of water supplyto bioreactor: in a closed system container/membrane bioreactor, and in an open system withcontinuous water flow through membrane bioreactor
