ammonium removal by nitrification and denitrification in an integrated fixed film activated sludge process
conclusions based on nitrification and denitrification data, the best condition for nitrifying/ denitrifying performance was obtained by modified-ifas. hence, the modification can be used to obtain the best activities of microbial and nitrogen removal improvement. results employing the bet, surface area (sa), total pore volume (vp), and average size of the nanostructure were 0.4026 m2/g, 3.8089...
متن کاملModel for nitrification in activated sludge process.
A model for the simulation of nitrification in activated sludge is presented and calculations are compared with experimental results from different sources. The role of protozoa and the influence of reactor type and of diurnal variations in flow and strength of the sewage are considered. Favorable conditions for nitrification are low rates of sludge wasting, high temperatures, plug-flow-type re...
متن کاملA pilot study on suspended activated sludge process augmented with immobilized biomass for simultaneous nitrification and denitrification
Concurrent nitrification and denitrification (CND) are natural phenomena in the soil environment that can be applied in wastewater treatment for enhanced total nitrogen removal. However, significant renovation is necessary for existing plants to equip them for nutrient removal. At a domestic wastewater treatment plant, we performed a pilot test by installing bioplates with entrapped biomass in ...
متن کاملNitrification Inhibition by Heavy Metals in Activated Sludge Process
Nitrification is the most sensitive part in the biologic nutrient removal of wastewaters, since the growth rate of nitrifying microorganisms is very lower and strongly dependent on temperature, substrate concentration, oxygen content, pH, and the presence of inhibiting components. This review addresses the nitrification inhibition by heavy metals. This inhibition can be quantified by different ...
