The Atlantic City Municipal Utilities Authority (ACMUA) has established a goal of upgrading their filtration facilities to allow for: additional capacity (increase from 18 MGD to 22 MGD); the ability to remove filters from service to perform maintenance; and, to meet a turbidity goal of 0.1 NTU at their filtration plant. A pilot study was conducted to evaluate the Atlantic City Municipal Utilities Authority's (ACMUA) existing filtration facilities to determine the potential for increasing filtration capacity. The three alternative media configurations and the control were tested at a loading rate of 5.5 gpm/sf. The tests were conducted with four 4-inch diameter filtration columns operating in parallel. The flow treated by the filtration columns was taken from the top of the existing filters. Data recorded included turbidity, particle counts and headloss. Further information presented includes: ACMUA's filter plant description; pilot testing; and pilot test results. Includes figures.
