Emulsion Pertraction Technology In Hollow Fiber Modules: Application To Metallic Valorisation From Wastewater

Minimum Membrane Area of a Pertraction Process for Cr(VI) Removal and Recovery

A pertraction membrane plant is designed for the treatment of wastewater containing hexavalent chromium and its recovery for industrial reuse. Pertraction is a new technology that combines the efficiency of emulsion liquid membranes with the advantages of using hollow fibber membrane modules. It can selectively remove low concentrated metals from process streams and reach high concentrations of...

Intensification of membrane processes. Remediation of groundwaters by emulsion pertraction as a case study

Membrane technology is strongly related to the process intensification strategy, being the design of new operating modes one of the objectives, with the focus in the replacement of large, expensive and energy-intensive equipment with ones that are less costly, more efficient or that combines multiple operations into a single apparatus [1]. Membrane contactors are expected to play a decisive rol...

Optimal Groundwater Remediation Network Design using Selective Membranes

This work deals with the optimal synthesis of groundwater remediation networks for the valorization of anionic pollutants by means of emulsion pertraction technology using hollow fiber modules (HFM). Superstructures that incorporate all possible design alternatives are proposed. The aim of this work is to obtain a minimum cost groundwater remediation network that allows treatment of groundwater...

CO2 Capture by Dual Hollow Fiber Membrane Systems

In this paper, a system for efficient removal of carbon dioxide by hollow fiber membranes is proposed. The system is compact, and it is very useful for application in the offshore energy industries. In particular, it is used to removing CO2 from the exhaust of power generation facilities on offshore platforms.The proposed dual membrane contactor contains two types of membranes (polypropylene me...
