Efficient recovery of organic components from wastewater with communiters is a future techniqueto be developed for sustainable society. This paper discusses techniques to recover organics, suspended andsoluble, from communiter wastewater. In order to determine an optical screen mesh size to collect suspendedsolids, TC, TN, and TP of separated solids in several kinds of communiter wastewater are examined. Availabilityof activated carbon and charcoal as adsorption media is also examined to recover soluble organics efficiently.The conclusions are that the optimal screen mesh size is 0.850mm for effective recovery of suspended organics;more than 25mg/L of activated carbon is necessary for that of soluble organics; and 1g of charcoal in 2.00 to4.75mm of diameter adsorbs 0.5-0.75g of oil.
