Reverse osmosis

TL;DR: In this article, a pilot-scale membrane system was used for decolorization and removal of chemical oxygen demand and salts in dyewaters from dyewashing processes in a weaving industry.

TL;DR: In this paper, a factorial design was employed to integrate four independent factors, i.e., membrane type, dissolved organic carbon (DOC) composition, divalent cation and monovalent cation, to investigate their influences on specific flux decline and fouling.

TL;DR: In this paper, the effect of an imposed pressure gradient between the two reservoirs, acting in the same direction as the concentration gradient, is examined to establish the domains of osmosis and reverse ossosis, and the influence of unequal diffusion coefficients for anions and cations (diffusional potential) on the osmotically driven flows is studied.

TL;DR: A critical review of the reported performance of reverse osmosis (RO) and capacitive deionization (CDI) for brackish water desalination from the aspects of engineering, energy, economy and environment reveals that both RO and CDI should play important roles in water reclamation and resource recovery from brackian water, especially for inland cities or rural regions.

TL;DR: The obtained organic micro-pollutant rejections and water fluxes under various feasible operating conditions indicate that the FO process has potential to be a viable treatment for wastewater containing organic micro -pollutants.
