Modelling the behaviour of trace organic compounds during an aquifer recharge pilot-scale experiment: the SMARTplus tank
Birte Moser | Carl von Ossietzky University of Oldenburg | Germany
The sequential managed aquifer recharge technology, based on an artificial sequence of oxic-anoxic zonation to improve the efficiency of biodegradation processes along the soil passage, is tested in a highly controlled-engineering tank experiment. We aim the numerical characterization of hydraulic conditions and removal efficiency of trace organic compounds inside the tank before re-aeration.
Operating world’s first UV Hypo AOP System for Reuse – An Operators Story
Jens Scheideler | Xylem Services GmbH | Germany
The UV AOP system at the Terminal Island Water Reclamation Facility is the first Greenfield AOP system that utilizes the combination of UV light and sodium hypochlorite for potable reuse. This presentation describes the experiences and lessons learned from the first year of operation from the chief operator’s perspective.
Total Organic Carbon as a Surrogate for the Removal of Pharmaceutical and Personal Care Products in the Coagulation-Flocculation Process
Kyle Pierce | University of Nevada, Reno | United States
Jar testing is widely used for removal of organics in drinking water treatment. With reuse as the final goal for the treated wastewater, removing as many organics and inorganics from the water is key. There are detectable concentrations of pharmaceuticals and personal care products (PPCPs) being observed in surface water so finding a cheaper alternative to remove PPCPs is the goal.
Effects of Water Matrices on Radical Distribution in the UV/monochloramine Process for Potable Water Reuse
Zhuozhi ZHONG | Hong Kong University of Science and Technology | China
This study investigated the effects of monochloramine, chloride, bicarbonate and effluent organic matter (EfOM) on the concentrations and distributions of radicals in the UV/monochloramine process under the conditions relevant to the advanced treatment of secondary effluents.
