6.2.2 Advanced Nutrient Elimination on a Global Scale

Globally, wastewater treatment plants remove only 20% of P and 10% of N contained in wastewater (Fig. 6.1). The reason is that low- and middle-income countries have not invested in nutrient-eliminating wastewater treatment plants [47]. The same figure projects that the amounts of N and P emitted to the environment will increase in the future: it is not possible to construct infrastructure rapidly enough to cope with the increased nutrient emissions of a growing world population.
