Ozone absorption in raw waters [PDF]
Chemical Industry and Chemical Engineering Quarterly, 2008 The ozone absorption in raw water entering the main ozonization step at the Belgrade drinking water supply plant was investigated in a continuous stirred tank reactor (CSTR). A slow chemical reaction rate of dissolved ozone and pollutants present in raw water have been experimentally determined. The modified Hatta number was defined and calculated as a

The promotion of drug rectal absorption by water absorption
Journal of Pharmacy and Pharmacology, 1985 Abstract The promotion of the rectal absorption of antipyrine by sodium taurocholate (TC-Na) or sodium ethylenediam-inetetraacetate (EDTA-Na) has been examined by in-situ recirculating perfusion in the rat. These promoters significantly increased water influx, efflux and antipyrine absorption clearance (CLAP).

International Journal of Concrete Structures and Materials, 2020 The high water-absorption of lightweight aggregate causes a high slump loss and poor workability of concrete. A prewetting process is usually recommended to compensate for the workability problem, but its application needs more delicate consideration in ...
