MANAGEMENT OF WASTEWATER TREATMENT BY OPTIMUM AERATION TIME OF SURFACE AERATORS IN SUAN SUNANDHA RAJABHAT UNIVERSITY

ANAT THAPINTA

Abstract:

This research focused on management of wastewater treatment by comparing the efficiency of surface aerators with different aeration times in natural ponds in Suan Sunandha Rajabhat University. In doing so, the aeration time of surface aerators was divided into 2 groups including the groups of 8 hours (8-0/opened-closed) and 4 hours (2-2/opened-closed) per day. As a result of the study, it was found that the efficiency of wastewater treatment by these 2 groups of aeration time operation was not statistical different (Sig.>0.05). It is, therefore, recommended to choose the 4 hours (2-2/opened-closed) of aeration time operation instead of the other. It was also found that the cost of electricity used by the operation of 4 hours (2-2/opened-closed) of aeration time per day of surface aerators was 122,088.85 Baht cheaper than that of the operation of 8 hours (8-0/opened-closed) in one year. Thus, it will be able to save more electrical power used as an energy source for this purpose.
