Ever heard of water filtration systems made from rubber tyres? Apparently, they work four times faster than conventional filters!Rubber tyres, the kind that lie at the bottom of rivers and at the back of junkyards the world over, could be ideal water filters says an environmental engineer at Penn State university in the US.
Yuefeng Xie says his “crumb rubber” suffers none of the problems of traditional water filtration systems and as a result can filter wastewater up to four times faster. Xie and his team believe that crumbs of rubber, 1 to 2 millimetres across, are an ideal solution because the crumbs are compressible. As a result, regardless of how the filter is stacked the crumbs at the bottom of the column are always smallest because they are squashed by the weight of the column.
