WebNov 1, 2024 · Consequently, the profound denitrification of low C/N ratio water and wastewater (carbon sources cannot provide sufficient electron donors for microbial denitrification, and this ratio is generally considered to be less than 20:1) has gained attention in the academic world (Peng et al., 2024). On the other hand, the rapid increase … WebNitrification. Nitrification plays an important role in the biological water purification in the removal of nitrogen out of the waste water. Nitrogen occurs in waste water usually as ammonium (NH 4+) or bonded in organic compounds. Organically bonded nitrogen is transformed into ammonium when these compounds are depleted by microorganisms.

WebIn contrast to the plastic tubes (Kaldnes), the sponge cubes stored remarkable amounts of substrate. The maximum denitrification rate with acetate as a substrate was 420 gNm-3d-1 at 10 degrees C and 730 gNm-3d-1 at 20 degrees C. An average denitrification rate of 240 gNm-3d-1 (10 degrees C) was achieved with wastewater. WebNov 15, 2016 · Abstract and Figures.
