Device Mines Precious Phosphorus From Sewage 96

ckwu writes "Scientists predict that the scarcity of phosphorus will increase over the next few decades as the growing demand for agricultural fertilizer depletes geologic reserves of the element. Meanwhile, phosphates released from wastewater into natural waterways can cause harmful algal blooms and low-oxygen conditions that can threaten to kill fish. Now a team of researchers has designed a system that could help solve both of these problems. It captures phosphorus from sewage waste and delivers clean water using a combined osmosis-distillation process. The system improves upon current methods by reducing the amounts of chemicals needed to precipitate a phosphorus mineral from the wastewater, thus bringing down the cost of the recovery process."

    Even if the phosphorus 'shortage' isn't a valid reason for this tech, algal blooms ARE a serious threat to farming & fisheries produce, as well as native wildlife.

    I for one cannot wait to see these installed along the banks of the Murray-Darling River
