Abstract:The research aimed at determining effectiveness of nitrates removal from natural ground water in a membrane bioreactor (MBR) with capillary polymer membranes. The paper presents an influence of nitrate loading on denitrification in an anaerobic packed-bed reactor, a sanitary and epidemiological analysis in a culture apparatus and effectiveness in removal of microorganisms from a post-culture effluent during microfiltration. The installation used for denitrification, which contained a bioreactor and membrane module made of capillary fibers, was fed continuously for several months with natural ground water enriched with organic carbon (methanol).
