Taking out the Salt

The large amounts of water required in the hydraulic fracturing of shales for oil or gas is a pressing concern. In hydraulic fracturing, water is sent  down underground at high pressures to fracture the rocks below, allowing gas or oil to be released and captured. When water returns to the surface it often contains large amounts … More Taking out the Salt

The benefits of hybridising electrodialysis with reverse osmosis

In a recently published paper in the Journal of Membrane Science, Prof. Syed Zubair, Prof. Lienhard and I reported on how the cost of achieving high purity water with electrodialysis, an electrically driven technology, can be reduced through hybridisation with reverse osmosis, a pressure driven technology. In reverse osmosis, water is pressurised and forced through a membrane that … More The benefits of hybridising electrodialysis with reverse osmosis
