The overall goal of this research was to determine optimum conditions for biological treatment of drinking water. The specific objectives addressed in this paper were to: 1) assess the effect of ozone dosage and hydraulic loading on biological activity in anthracite/sand filters and in granular activated carbon (GAC) contactors; 2) compare biological treatment steps to physical/chemical treatment steps; 3) determine the effect of ozone dose on assimilable organic carbon formation; 4) establish the reduction in chlorine demand by biological treatment steps.
