  • Syntrophy of aerobic and anaerobic ammonia oxidisers

    Deammonification is known as an efficient and resource saving sidestream process option to remove the nitrogen load from sludge liquors. The transfer of the intermediate product nitrite between both syntrophic groups of organisms – aerobic and anaerobic ammonia oxidizers (AOB) – appears very sensitive to process conditions such as temperature, dissolved oxygen (DO) and operating nitrite level. ...

  • Biosorption kinetics and isotherms of copper (II) ions from aqueous solution and application of the MATLAB

    In this study, biosorption kinetic and isotherm models were examined by the MATLAB for removal of copper ions from aqueous solution freely dead single Rhizopus arhizus and mixed dead waste sludge biomass. The copper ions removal efficiencies at equilibrium were 98%, 95% and 92% for freely dead R.arrhizus and two types of dead waste sludge. The experimental data fitted to pseudo-second order ...
