Thesis ; no. EV-80-19 A thesis submitted in partial fulfillment of the requirements for the degree of Master of Engineering, School of Environment, Resources and Development Thesis (M.Eng.) - Asian Institute of Technology, 1980 Conventional chemical precipitation methods need high chemical dosage and extra reactors to obtain an acceptable phosphorus reduction. These are the major prohibitive factors when this process is considered. In a rotating biological contactor, phosphorus removal can be achieved with a rather low Al/P ratio and no extra facility needed. It is clear to see that simultaneous ·removal in a RBC has certain advantages over the conventional precipitation method. pH is a major consideration which strongly affects phosphorus removal efficiency. in this process, pH is not so strictly limited as the precipitation-method does, During the whole experiment, chemical dose had no adverse effect on COD, NH4-N and SS removal.
