On this year’s World Water Day, the UN has called for much more wastewater to be treated and recycled. On average in low-income countries, only 8 percent of domestic and industrial wastewater is treated, compared to 70 percent in high-income countries, the report said. For example, phosphorus recovery from wastewater is becoming a viable alternative to increasingly scarce mineral phosphorus reserves. A business opportunityRemoving and recovering phosphorus (and other nutrients, including nitrogen) from wastewater has a double benefit: It prevents hypertrophication of lakes and rivers, and it recuperates a valuable finite resource that’s essential for agriculture. That’s why companies like Vancouver, Canada -based Ostara and Delft, Netherlands -based Lenntech offer technologies for nutrient recovery to municipal or industrial wastewater managers.
