The long-term strategic design of wastewater treatment plants (WWTPs) requires measures to address a range of sustainability challenges including rapid population growth, climate change, urbanization, and stressful position for some natural resources. The resource recovery from wastewater has been extensively elaborated in scientific publications along with rapid development of nutrient recovery technologies in the market. However, due to various technical and nontechnical reasons (economic, environmental, and societal) the implementation in municipal WWTPs is still poor. This chapter has focus on phosphorus as one of the resources in wastewater and investigates drivers of phosphorus recycling, criteria for the selection of phosphorus recovery route and final products. Further, crystallization, as a relevant techniques for nutrient recovery from nutrient-rich wastewater streams has been discussed with struvite and calcium phosphates as the final products. This chapter aims to improve the understanding of the phosphorus recovery from nutrient-rich streams at WWTPs. |
