Phosphorus Recovery from Wastewater
Urine, a product of human excretion, is a component of urban wastewaters. Urine is one of the richest and most accessible sources of phosphorus and nitrogen to make struvite that can be obtained by a precipitation reaction at basic pH, helped by magnesium dependence.
The laboratory activities in this toolkit are meant for pupils 15-19 years old. The laboratory activity is structured in a theoretical learning phase under the guidance of the trainer and two practical phases. The aim is to obtain the P recovery as struvite extracted from wastewaters (synthesized in the lab) by using very common materials.
