Abstract: Factors affecting the nitrification rate in post‐secondary water hyacinth treatment systems are investigated. Parameters studied include ammonia concentration, dissolved oxygen concentration, and system mixing. The ...

Abstract: The feasibility of an offline biological regeneration (OBR) process for granular activated carbon is investigated. A predictive model is presented and validated with data collected from bench‐scale experiments. Based on ...

Abstract: Recently, calcium magnesium acetata (CMA) was identified by the Federal Highway Administration as a potentially suitable, noncorrosive road deicer substitute for sodium and calcium chloride. Research on the environmental ...

Abstract: A laboratory investigation was conducted to determine the relative importance of the physiological state of the reactor population and biomass concentration on mitigating short-term toxic shocks. The studies were conducted ...

Abstract: This study evaluated the partitioning of polychlorinated biphenyls (PCBs) during long-term, passive, land biotreatment of PCB-impacted industrial lagoon sediments. Over six years under field conditions, two land treatment ...
