Here in Wales we take water for granted. We turn on a tap and out it pours. But despite being surrounded by聽oceans, there's not enough聽clean and drinkable water聽to go around. The World Health Organisation predicts that by mid-century, around four billion people will be without this precious resource.聽New techniques to clean and recycle water are desperately needed. And this week Adam visits the Centre for Water Advanced Technologies and Environmental Research in Swansea, to learn more about聽its pioneering work with membranes. These super-sieves, as we might crudely call them, offer a relatively 聽low energy,聽environmentally friendly way of filtering water. And they can be used in the food and pharmaceutical聽industries too. The team at CWATER, attached to Swansea University, are聽leading the way in developing high tech, hi-spec, purpose made membranes that could make all the difference聽in future water treatment programmes.
