摘要

Urine recovery in buildings could be an effective way to recover, at the source, nutrients that would otherwise end up in a wastewater treatment plant. However, challenges have emerged with this practice concerning the collection and sanitization of urine in buildings. In fact, current buildings are not designed to receive these systems and integrated solutions able to self-manage the whole process of urine recovery, including the separation, maturation and storage phases, are not available in the market.This work discusses the main technical features of a new approach to collect urine and manage the recovery process at the building level. Several functional aspects, including the dilution ratio of urine in the collected effluent, filling speed of the maturation tanks and storage temperature were studied. Chemical and microbiological analyses carried out over 6 months with real urine have shown that hygienization conditions compatible with gardening and agricultural applications can be achieved.
