Pathogen Removal from Wastewater during Groundwater Recharge 2013-11-17 .txt text/plain 10527 533 53 Studies indicate that bacteria and viruses are not removed effectively from wastewaters during primary treatment [19] ; removal of viruses during secondary treatment (active sludge) is dependent largely on virus adsorption to solids. [40] with cores of sandy forest soil receiving poliovirus in sewage effluent at various pH levels between 5.5 and 9.0, virus retention was best at pH 5.5, and the release and migration of retained viruses by subsequent distilled water applications was lower from the cores that re ceived sewage effluent having lower pH values. [57] on virus survival and movement in a rapid-infiltration system for wastewater, the rate of inactivation of indigenous viruses was greater in the fall than in the winter, possibly due in part to the effects of higher temperatures in the former season. ./cache/cord-025995-nxeg03xj.txt ./txt/cord-025995-nxeg03xj.txt
