چکیده
Abstract This work presents the elimination of arsenic ions from synthetic produced water via hollow fiber supported liquid membrane (HFSLM). Results demonstrate that in wastewater can be successfully treated to meet standard as formulated by Ministry Industry and Natural Resources Environment, Thailand. The discharged limit industrial must not greater than 250 ppb. In a single-step operation, are extracted stripped. Percentages extraction stripping proved 100% 98%, respectively. Optimum conditions found 0.68 M Aliquat 336 dissolved toluene membrane, at pH 12 feed solution, having mixture HCl thiourea synergistic strippant, flow rates both strippant solutions 100 mL/min. A mathematical model, developed predict final concentration solutions, is seen fit well with experimental results.

Hollow fiber membrane adsorber: Mathematical model
Two opposite design strategies for ultrafiltration/microfiltration filters, (1) reduction of concentration polarization and particle deposition to increase permeate velocity and (2) utilization of particle deposition on membrane surface to produce an additional (to permeate) volume of clarified water, are analyzed. It is shown that the first strategy is always associated with additional expendi...
متن کاملMathematical Modeling and Numerical Simulation of CO2 Removal by Using Hollow Fiber Membrane Contactors
Abstract In this study, a mathematical model is proposed for CO2 separation from N2/CO2 mixtureusing a hollow fiber membrane contactor by various absorbents. The contactor assumed as non-wetted membrane; radial and axial diffusions were also considered in the model development. The governing equations of the model are solved via the finite...
متن کاملFailure Mechanisms of Hollow Fiber Supported Ionic Liquid Membranes
Hollow fiber supported ionic liquid membranes (SILMs) were tested using the bubble point method to investigate potential failure modes, including the maximum transmembrane pressure before loss of the ionic liquid from the support. Porous hollow fiber supports were fabricated with different pore morphologies using Matrimid(®) and Torlon(®) as the polymeric material and 1-hexyl-3-methylimidalzoli...
