Abstract. Phosphorus is a nutrient necessary for the development of crops and is thus commonly applied as fertilizer to sustain agricultural production. It occurs naturally, in indefinite quantities of uncertain quality in phosphate rock formations, but also accumulates in urban and livestock wastewater wherefrom it is often lost as a pollutant. Recovering phosphorus from wastewater, however, is feasible through struvite crystallization technologies and has the potential to reduce phosphorus pollution of the environment as well as lower the agricultural demand for artificial P fertilizers. In this study, we developed a model to assess the global potential of P fertilizer recovery from wastewater and to visualize its trade at sub-national resolution. Results show that humans discharge a maximum of 3.7 Mt P into wastewater, thereby potentially satisfying 20 % of the global fertilizer demand. Provided 2015 market dynamics, however, the model determines that only 4 % of this discharge is technologically and economically recoverable in a market that offers cheap rock phosphate products also. The results of this study demonstrate that in the current economic context, phosphorus recovery from wastewater offers only a small contribution to resolving global phosphorus issues. Nevertheless, this recovery offers many wastewater treatment facilities the opportunity to contribute to creating sustainable communities and protecting the environment locally, while reducing their own operational costs.

A full-scale struvite crystallization system was operated for the treatment of the centrate obtained from the sludge anaerobic digester in a municipal wastewater treatment plant. Additionally, the feasibility of an industrial grade Mg(OH)2 as a cheap magnesium and alkali source was also investigated. The struvite crystallization plant was operated for two different periods: period I, in which an influent with low phosphate concentration (34.0 mg P·L−1) was fed to the crystallization plant; and period II, in which an influent with higher phosphate concentration (68.0 mg P·L−1) was used. A high efficiency of phosphorus recovery by struvite crystallization was obtained, even when the effluent treated had a high level of alkalinity. Phosphorus recovery percentage was around 77%, with a phosphate concentration in the effluent between 10.0 and 30.0 mg P·L−1. The experiments gained struvite pellets of 0.5–5.0 mm size. Moreover, the consumption of Mg(OH)2 was estimated at 1.5 mol Mg added·mol P recovered−1. Thus, industrial grade Mg(OH)2 can be an economical alternative as magnesium and alkali sources for struvite crystallization at industrial scale.

Struvite Crystallization

Struvite crystallization is an efficient method for phosphorus recovery from animal manure wastewater. However, large amount of organic coexisting impurities, contained in animal manure wastewater, might influence struvite crystallization. In this study, the effect of typical organic matter contained in animal manure wastewater, such as butyric acid, fulvic acid, tetracycline, on phosphorus recovery was examined. The following conclusions were drawn: (1) with an increase in butyric acid concentration in animal manure wastewater, phosphorus recovery efficiency did not change significantly; (2) with an increase in fulvic acid concentration in animal manure wastewater, phosphorus recovery efficiency decreased obviously; (3) with an increase in tetracycline concentration in animal manure wastewater, phosphorus recovery efficiency decreased slightly.
