Isolation of enteroviruses from oxidation pond waters.
Enteroviruses were isolated from influent and effluent wastewaters of two types of oxidation lagoons during an 18-month study. Isolations, performed by sewage concentration and direct assay, were low in number and did not follow a seasonal trend. The younger treatment system, using aeration and effluent chlorination, was more efficient at removing viruses than the aging, static complex.
متن کاملPond Sludge : Electrokinetics , Carbon Dioxide Extraction , and Supercritical Water Oxidation
At DOE sites, significant amounts of Job Control Waste (JCW) need to be disposed. This JCW is generated and contaminated with polychlorinated biphenyls (PCBs) during clean-up operations. A commercial, plant-based absorbent material, “Toxi-dry”, is used extensively for decontamination and decommissioning of DOE waste sites and is classified a hazardous JCW after use. In this investigation, 1,2,4...
متن کاملSingle walled carbon nanotube in the reaction layer of gas diffusion electrode for oxygen reduction reaction
In this paper, the effect of surface area of reaction layers in gas diffusion electrodes on oxygen reduction reaction was investigated. For this purpose, various amounts (0.1, 0.2, 0.3, 0.4, 0.5, 1, 1.5 and zero %wt of total loading of reaction layer) of single walled carbon nanotube (SWCNT) were inserted in the reaction layer. The performance of gas diffusion electrodes for oxygen reduction re...
متن کاملEffect of hard detergents on algae in a high-rate-oxidation pond.
Regular concentrations of hard detergents in domestic wastewater do not affect algal growth in a high-rate-oxidation pond. The addition of nonionic hard detergent at concentrations above 60 mg/liter decreased the algal concentration in the batch culture, and complete lysis of algal cells was observed within a few days at a detergent concentration of 100 mg/liter.
متن کاملEmergy Distribution in Oxidation Pond and Constructed Wetland treating a Domestic Wastewater
Two identical pilot-scale reactors – one as an oxidation pond (OP) and the other as a freewater-surface-flow constructed wetland (CW) planted with Cyperus papyrus – were fed with a lowstrength domestic wastewater at the organic loading rate of 16 kg BOD/ha-d. The purpose of this study was to investigate how the solar energy dissipated into the biomass productivities during the wastewater treatm...
