In previous papers, a potato juice separating system was studied. Using this system, the BOD of separator waste was low. Next, the "Funsha-Hoshiki" treatment of separator waste in this system was studied. Although utilization of potato juice as feed was considered, several methods of treatment of waste potato juice were studied which could be used by all potato starch factories except those operating on a large scale. The results were as follows : (1) In the aeration test of potato starch waste, COD removal was influenced by initial COD content .In potato juice it was especially low. It was not so effective to raise the treating temperature and increasing the aeration.(2) As compared with COD removal, the BOD of potato starch waste was not as efficiently removed in an anaerobic lagoon test at 10℃ and purifyign effect of this treatment was not so influenced by the initial concentration of waste.(3) In aeration of lagoon tests effluent, the settling quality was improved, but COD removal was low. It had the same tendency in the settling test when Ca(OH)_2 was added.
