Project Summary

New ED - Bipolar Membrane Electrodialysis for Remediation of Highly Saline Waste Streams

New ED, a project acronym for "advanced bipolar membrane processes for remediation of highly saline waste water streams" is a three-year project co-funded by the European Commission within the seventh framework program. It aims at closing water cycles by developing new bipolar membranes for electrodialysis, to treat industrial brine streams and transform them to valuable products.

NEW ED is a Collaborative Project (Grant Agreement number 227004) co-funded by the Research DG of the European Commission within the joint RTD activities of the Environment and NMP Thematic Priorities. The project is performed by a consortium of 6 partners from four countries and it is coordinated by RWTH Aachen University.

Project summary

New ED aims at closing industrial water cycles and reducing the amount of waste water streams with highly concentrated salt loads stemming from a broad range of industrial production processes by exploiting the waste components (salts) and transforming them to valuable products. This will be achieved by developing new nanoporous bipolar membranes for electrodialysis using bipolar membranes (EDBM), a new membrane module concept and by integrating this new technology into relevant production processes.

The bipolar membrane process produces acids and bases from their corresponding salts by dissociating water at the interface within the bipolar membranes. However, EDBM so far has been applied only in niche markets due to limitations of the current state of membrane and process development. Major drawbacks of the classic EDBM process are low product purity, limited current density and formation of metal hydroxides at or in the bipolar membrane. The objective of this project is to overcome these limitations by developing a new bipolar membrane and membrane module with a new water transport concept into the inner layer of the bipolar membranes.

Several promising membrane configurations will be developed and tested. New module concepts will be investigated to exploit the full potential of the new bipolar membrane technique. Integration of the developed membranes and modules into relevant production processes is an essential part of the project.

The strategic aim of New ED is inline with the vision document and strategic research agenda put forward in 2006 by WSSTP (Water Supply and Sanitation Technology Platform) on a European level that specifically asks for recovery of materials from brines, treatment of brines from specific processes and development of technologies for treatment of concentrated salt streams.
