dc.description.abstractDuring the three months research period (October 1989 - January 1990) the average nitrification efficiencies for municipal sewage were 48% and 61 % for respectively one-step and two-step biological submerged filters placed after chemical precipitation. Correspondi- ng nitrification rates were 0.69 and 0.56 g NH4-N/m² d. The air/liquid ratio (m³/m³) varied from 18-35 for the diffused aeration, giving high 02-concentrations, but indicating an inefficient aeration system. No logging problems occured with the backwashing routines used.nb_NO
