Full Description

The New Jersey Department of Environmental Protection (NJDEP) recognized the need for proactiveand innovative steps to safeguard the water supplies in New Jersey when the state experienced a record-breakingdrought in 2002. Utilizing the State 2005 fiscal year budget, the Legislature made $35 millionin funding monies available from a 1981 Water Supply Bond Fund in 2004. A call for funding proposalswas released to water purveyors, wastewater dischargers and agricultural users throughout the state forWater Supply Demonstration Projects. Due to increasing pressures on potable water resources in itsservice area, Logan Township Municipal Utilities Authority (LTMUA) hired Metcalf a $4.1 million grant for the firstindirect potable reuse (IPR) project in the northeastern US. The treatment train for the AdvancedWater Treatment Facility (AWTF) at LTMUA was selected based on an evaluation of the alternatives,with finished water quality goals set to meet or exceed drinking water standards. The train incorporatedmembrane bioreactors (MBR) which provide a high sludge age and a physical barrier to microbes andorganics; reverse osmosis (RO) to remove dissolved contaminants and provide a second microbialbarrier; and, an advanced oxidation process (AOP) with ultraviolet (UV) light and hydrogen peroxide toprovide final disinfection as well as oxidation of any ultra-low molecular weight compounds. Theproduct will be 750,000 gallons per day (gpd) of water that meets or exceeds drinking water qualitystandards prior to injection. The injected product will blend with native groundwater for approximatelythree years. The proposed treatment train was pilot tested at LTMUA from August through November 2005 toconfirm performance, develop design criteria and build operator understanding of the proposedprocesses. During the pilot testing period M
