Abstract

Phosphorus and nitrogen can be recovered through controlled crystallization of struvite (MgNH4PO4 6H2O) from digested sludge streams, reached in N, P, Mg (as the result of microorganisms activity) in WWTP. Recovered struvite can be sold as valuable fertilizer. In the paper the results of research on the influence of molar ratio of struvite components, temperature and residence time on the process efficiency were investigated. Various dependences were observed, and as the final result it is supposed to state the process conditions, which allow to obtain product, valuable from economical and ecological point of view.
