In a new paper published in Water Research, Senecal et al. assessed what hygienic health risks may occur when human urine is dehydrated. The experiment was set up to simulate that the last person using the toilet (before the dehydration medium is changed) is contaminating the medium with misplaced faeces, with no time for dehydration of the urine, i.e. a worst-case scenario. It was found that urine dehydration in itself achieved a concentration < 1 A. suum per 4 g of dehydrated medium which fulfils the WHO guidelines for unrestricted use.
Jenna Senecal, Doctoral Candidate at the Environmental Engineering Unit, Department of Energy and Technology will defend her licentiate thesis entitled, Urea stabilisation and dehydration for urine-diverting toilets: System and hygiene evaluation.
