Co-immobilized micro-algae and nitrifying bacteria for ammonium removal
1. Introduction Ammonium is toxic to aquatic species and causes eutrophication in natural water environments. The low maximum growth rates and growth yields of nitrifying bacteria make it difficult to obtain and maintain sufficient nitrifying bacteria in traditional wastewater treatment plants. It has been pointed out that the immobilization of nitrifying bacteria to an appropriate carrier material is a feasible method to overcome the problem associated with the low growth rate constants of nitrifying bacteria. Considering that there are few researches about ammonium degradation by co-immobilized microalgae and nitrifying bacteria, this study was designed to investigate the characteristic and kinetic behavior of using mixed micro-algae and nitrifying bacteria immobilized onto macroporous carrier and to determine the kinetic constants in ammonium removal process.
