The supplemental treatment plant will use lime, recarbonation, filtration, granular activated carbon and ozone. Gwinnett County, GA plans to construct a similar system and presented data at the conference. The type of reuse for Gwinnett was not discussed. West Palm Beach is pursuing a wetlands based indirect reuse project. A mixture of ground water and surface water from the wetlands would be used for the supply.
Secondary treatment meeting Florida requirements for discharge is proposed.
Palm Beach County is developing a system of discharge to a canal after a high level of treatment. Wells would be constructed along the canal and a mixture of ground water, surface water and reclaimed water will be treated for potable purposes by reverse osmosis. Several papers were presented which discussed the San Diego water reuse project. The system will apparently meet the criteria discussed earlier by the California Department of Health Services. Experimental work involving preparation for water reuse in San Diego were discussed by several presenters.
