Water Separation

Innovative technologies are needed to attend the increasingly strict requirements for produced water treatment, since most of the separation processes are limited to particles larger than 10 μm. Separation processes using ceramic membranes are attracting great interest from academic and industrial community. Nevertheless, few studies, especially numerical, regarding the inorganic membrane’s application for the polluted water separation have been reported. In the present work, therefore, a study of fluid-flow dynamics for a laminar regime in porous tubes (tubular porous ceramic membrane) has been performed. The mass, momentum and mass transport conservation equations were solved with the aid of a structured mesh using ANSYS CFX commercial package. The velocity of local permeation was determined using the resistance in series model. The specific resistance of the polarized layer was obtained by Carman-Kozeny equation. The numerical results were evaluated and compared with the results available in the literature, where by a good agreement with each other was found. The numerical results, obtained by the proposed shell and tubular membrane separation module, indicate that there is facilitation of mass transfer and hence a reduction in the thickness of the polarized boundary layer occurs.

Sorption Method

Bio-absorption has an unparalleled advantage over other traditional methods in removing and recycling heavy metal ions from waste water. Consequently, it has a promising future. In this paper, the traditional methods and the bio-sorption method via which heavy metals are removed from waste water are compared to summarize the mechanism of bio-sorption, the types of bio-sorbent, the factors that can influence bio-sorption and the state of its application in waste water treatment .

Treatment Application

TiO2 catalyst is n-type semiconductor material. As long as the semiconductor absorbs photons of no less than the band gap width，it enters the excited state together with the formation of light-induced hole in the valence band simultaneously. It is perfectly capable of capturing electronic,and the photo-induced electron e- in the conduction band also has high activity to form a redox system in the semiconductor surface through which most of the organic pollutants and partial inorganic pollutants eventually degrade into innoxious substances. It describes the application of photocatalytic oxidation technology in the field such as treatment of industrial wastewater (inorganic polluted water; dye wastewater; papermaking wastewater; pesticide wastewater; oily wastewater) and drinking water. The research shows that various indexes (chromaticity; COD; mineralization rate; bacteria inactivation rate, etc.) of this technology in water treatment application have achieved the required standards.
