TL;DR: In this paper, the influence of Schmidt number on the rate of mass transfer between a turbulent fluid and a pipe wall is investigated. But the Schmidt number is only applicable to a vanishingly small portion of the concentration field as Sc → ∞.
Abstract: New measurements are presented on the influence of Schmidt number on the rate of mass transfer between a turbulent fluid and a pipe wall. It is found that for large Schmidt numbers the fully developed mass transfer coefficient is related to the friction velocity and the Schmidt number by the equation
The experiments are accurate enough to rule out the Sc−2/3 or the Sc−2/3 relations commonly used, deduced from plausible limiting expressions for the eddy diffusivity close to a wall. It is argued that these expressions arevalid only over a vanishingly small portion of the concentration field as Sc → ∞.

TL;DR: A model was developed to predict the enhancement factor of ozone mass transfer from the following parameters: initial dye concentration, applied ozone dose, temperature and concentration of dissolved ozone in the organic-free water.

TL;DR: In this article, the NF45 membrane was characterized and its pure water permeability, the mass transfer coefficient of NaCl, and the mean radius of the membrane pores were determined.
Abstract: The study was concerned primarily with characterization of the NF45 membrane. Its pure water permeability, the mass transfer coefficient of NaCl, and the mean radius of the membrane pores were determined. Experiments run with five pure dye solutions and an industrial dye pulp solution confirmed the potential of nanofiltration membrane separation for the treatment of textile dye plant effluent. The effects of such significant parameters as initial solution concentration, transmembrane pressure, and type of dye on two fundamental characteristics of nanofiltration (flux and separation factor) were studied.
