Steady state analysis of membrane processes for the treatment of industrial effluents

Publisher Summary This chapter discusses the steady state analysis of membrane processes for the treatment of industrial effluents. The feasibility of operating a new membrane technology for the treatment of industrial effluents in a continuous mode is analyzed. The selection of the operating mode needs to be addressed at the conceptual design stage. The semicontinuous operation and the optimum operating conditions are reported. A steady state configuration is proposed, the corresponding modeling equations are developed, and a methodology for the selection of the operating conditions is presented. A given compound can be removed from the effluent in the extraction module, and simultaneously, it can be recovered in the stripping module, for recycling and reuse in the plant that generates the effluent. Environmental applications of this technology will reduce the amount of contaminant disposed off finally into the environment, leading to a cleaner technology. This fact motivates the need to promote its industrial application. The removal and recovery of Cr(VI) from surface treatment effluents is studied.
