The purpose of this article is to identify possible scenarios for the evolution of the European water supply and sanitation sectors (WSS) in the next 15 years, on the basis of empirical knowledge of its dynamics. These are: tendered market, tendered market ...
This paper estimates a translog cost function for Swiss water utilities. From the cost function, we are able to estimate measures of marginal costs as well as economies of production density, customer density and scale, which are important determinants in ...
The role of 5,10,15,20-tetraphenylporphyrinatocobalt(II) ([Co-(tpp)]) as a catalyst on molecular oxygen (O2) reduction by ferrocene (Fc) and its two derivatives, 1,1’-di-methylferrocene (DFc) and decamethylferrocene (DMFc) at a polarized water¦1,2-dichloro ...
The oxidation of iodide by synthetic birnessite (delta-MnO2) was studied in perchlorate media in the pH range 4-8. Iodine (I-2) was detected as an oxidation product that was subsequently further oxidized to iodate (IO3-). The third order rate constants, se ...
The objective of this study was to analyze the efficiency of Ag-doped aerogels in the removal of bromide and iodide from water. To test the applicability of these aerogels in water treatment, adsorption of bromide and iodide was studied under dynamic condi ...
As the World Health Organization (WHO) progresses with provisional Drinking Water Guidelines of 1 mu g/L for microcystin-LR and a proposed Guideline of 1 mu g/L for cylindrospermopsin, efficient treatment strategies are needed to prevent cyanotoxins such a ...
The applicability of ozonation to mitigate taste and odor problems in drinking water was investigated. Second-order rate constants of eleven taste and odor compounds with ozone and hydroxyl radicals were determined under laboratory conditions. Measured rat ...
This study quantifies the uncertainty involved in predicting micropollutant oxidation during drinking water ozonation in a pilot plant reactor. The analysis is conducted for geosmin, methyl tert-butyl ether (MTBE), isopropylmethoxypyrazine (IPMP), bezafibr ...
Kinetics, products, and pathways of 17 alpha-ethinylestradiol (EE2) transformation during chlorination of water with and without bromide (Br-) were studied to evaluate the effect of chlorination on the fate of steroid estrogens. Br- can be important for th ...
Reverse osmosis (RO) concentrate samples were obtained from a RO-membrane system that uses effluents of wastewater treatment plants (WWTP) as feed water for the production of drinking water. A number of different pharmaceuticals (e.g. antibiotics, contrast ...
