RESUMO:

Phosphorus is a limited natural resource, which is used in a variety of activities, characterizing itself as an important input for fertilizers used in agriculture and for the manufacture of cleaning products. On the other hand, this nutrient is one of the main agents that contribute to the eutrophication of lentic water bodies, since it is a limiting nutrient for the primary production, contributing to the occurrence of algal blooms. Its release into receiving bodies mainly occurs through anthropic actions, especially agricultural activities (diffuse pollution) and the release of domestic and industrial wastewater (treated or not). Phosphorus can be removed in sewage treatment plants in the form of a phosphate mineral hydrated by ammonium and magnesium - MAP, called struvite, which forms naturally, causing incrustations in the system pipes. As an alternative to minimize possible damage caused by phosphorus to the environment and sewage treatment plants and to become an alternative source of supply for the various activities, it is possible to recover the struvite in fluidized bed reactors by chemical precipitation, from of sewage sludge percolated. The objective of this work is to evaluate the potential of struvite removal from sewage sludge percolation and, consequently, the recovery of phosphorus in fluidized bed reactors with recirculation of seeds.
