Abstract: This research aims to improve the quality of swimming pool water at Faculty of Sport Science, Yogyakarta State University by electrocoagulation process with aluminum-graphite electrode. An effectiveness of the electrocoagulation was based on process time, electrical voltage, separation efficiency of metals ion, TDS, and pH values. The samples and electrodes were characterized by using scanning electrone microscope (SEM) and X-ray diffraction (XRD). The results showed that the optimum condition of potential and time of electrocoagulation were 10 volts and 24 hours respectively. Aluminum electrode that used as anode had some impurities. The quality of the swimming pool water based on the pH and TDS parameter after electrocoagulation process according to the regulation of Indonesian Ministry of Health No. 416 / Menkes / Per / IX / 1990 is as well as water quality standard of swimming pool which has the pH 6.7 and TDS 231.3.
Keywords: Swimming pool water, electrocoagulation, aluminum-graphite electrode.
