AbstractPolycyclic aromatic hydrocarbons (PAHs) and organochlorine pesticides (OCPs) contamination levels were determined in the water samples of Danube river (two sites in Romanian area), of one Romanian spring water (Pelisor), in tap water (from Constantza and from Borovetz) and sea water (the Black Sea and the Mediteranean Sea). These levels were compared to those available for other surface waters. The studied water samples were analyzed by gas chromatography with mass spectrometer detector ...

AbstractDrinking water treatment plays an important role in maintaining public health. Chlorine is the most often disinfectant used for microbiological protection of water. Required residual chlorine concentration must be in treated water when it leaves treatment plant, to comply with the regulations. The chlorine residual must be 0.5 mg/L at the entrance into the distribution system and 0.25 mg/l at consumers, according to the law. Any less and there is no guarantee that the water has adequate ...

Water residence time in pipelines for more than seven days in buried pipes and two days in above-ground pipes promotes the development of biochemical systems when the flow rates are low and very low having detrimental consequences on drinking water quality. These shortcomings are due to the residual chlorine decrease below the allowed technical limits (0.5 m/s) ...

Abstract The paper aims at supporting and catalysing discussions (and possible options) on how the widely common waste management concept could be efficiently transformed to a level where phasing out residual waste becomes technically feasible. As such, this paper presents thoughts on the (possible) future meaning of term “waste”, but it also addresses the important relationship between the terms “waste” and “level of country development”. Although this re...
