PRECIPITATION OF STRUVITE FROM AGRICULTURAL WASTEWATERS FOR THE FORMULATION OF ORGANOMERAL FERTILIZERS
agroindustrial waste, animal manure, composting, struvite.
The objective of this work is to evaluate the efficiency of the precipitated struvite from agroindustrial wastewater and composting as an alternative source of nutrients for the formulation of organomineral fertilizers. Scientific Hypothesis: Precipitated struvite from agroindustrial wastewater is an alternative source of nutrients for the formulation of organomineral fertilizers. General Objective: To evaluate the efficiency of the precipitated struvite of agroindustrial wastewater as an alternative source of nutrients for the formulation of organomineral fertilizers. Specific Objectives • To evaluate the efficiency of the precipitation of nutrients (ammonium and phosphorus) as struvite from agricultural wastewater • Optimization of precipitation parameters; • Formulate an organomineral granulate from struvite and composite precipitates; • Evaluate the release of nutrients (phosphorus, nitrogen and magnesium) from the formed struvite and granulates at different soil pH.
