TL;DR: It is evident from the literature survey that photocatalysis has good potential to remove a variety of organic pollutants, however, there is still a need to determine the practical utility of this technique on a commercial scale.

TL;DR: In this article, the effects of various operating parameters on the photocatalytic degradation of phenols and substituted phenols are presented, such as type of photocatalyst and composition, light intensity, initial substrate concentration, amount of catalyst, pH of the reaction medium, ionic components in water, solvent types, oxidising agents/electron acceptors, mode of catalyst application, and calcination temperatures.

TL;DR: In this paper, a computational fluid dynamics (CFD) simulation of a baffled tubular membrane channel containing a concentric rod for predicting turbulent flow has been investigated, where an array of baffles was inserted either on the rod or on the membrane wall for simulation.

TL;DR: In this article, the performance of a vibratory shear enhanced process (VSEP) using a nanofiltration (NF) membrane system for the removal of arsenic from drinking water as a function of retentate arsenate concentration, feed water composition, transmembrane pressure (TMP), vibration amplitude and pH.

TL;DR: In this paper, a tubular membrane channel containing a set of baffles was used for predicting turbulent flow and the simulation results indicated that the presence of baffle can improve the local shear stress on the membrane surface and produces eddy activities which enhance the filtration performance.
