Evaluation of the Feasibility of Struvite Precipitation from Domestic Wastewater as an Alternative Phosphorus Fertilizer Resource

<p>Finite phosphate rock ore reserves are estimated to be exhausted in 100 to 150 years. Phosphate rock ore is the single global source material for phosphorus fertilizer production. Once these reserves are gone, agricultural production will be negatively impacted. There are currently no alternative phosphorus resources. However, phosphorus concentrations present in human excrement traveling through domestic wastewater treatment facilities is being disposed of directly to the environment, often resulting in pollution problems. Recovering phosphorus from wastewater with struvite precipitation systems at wastewater treatment plants can alleviate future phosphorus scarcities. Evaluation of phosphorus recovery through struvite precipitation at wastewater treatment plants and a determination of the ability for the recovered material to serve as an adequate phosphate rock ore substitute are discussed in the following paper.</p>
