Effect of Selective Organic Fractions on Denitrification Rates Using Salsnes Filter as a Primary Treatment
The purpose of this project is to render wastewater treatment more attractive in terms of energy use and production by selective removal of organic matter (COD) with Salsnes Filter (SF) technology. Bench-scale SF fine mesh sieves were used as a primary treatment to obtain different organic fractions to test the effect on denitrification. Tests were performed using activated sludge (AS) and moving bed biofilm reactor (MBBR) processes on municipal wastewater collected from two full-scale wastewater treatment plants (wwtps) located around the Oslo region (Norway). It was observed during this study that 70 % of the organic matter was in particulate forms (pCOD). SF fine mesh sieves can remove up to 40 % of the pCOD (18 μm). The effect of pCOD removal on denitrification rates was very minor. For instance, filtration with 1.2 μm filter reduced, on average, the first DN rate by only 4 % and the second DN rate by 14 %.
