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
