Abstract-The effects of mechanical agitation on the stripping position contamination. Therefore, it is significant to attached-growth bio-film from ceramic particles were studied adopt the method of mechanical agitation to strip the bio-film under the conditions of different agitating speeds and durations. from ceramic particles. The results indicated that the stripping efficiency of bio-film was increased with the increase of agitating speed. The highest The main purposes of the study are (1) to investigate the stripping efficiencies at the low, middle and high speeds of 300, efficiency of mechanical agitation on the stripping of bio-film 600 and 1200 rpm/min were , and % respectively. from ceramic particles; (2) to study the effect of agitation on The incre
