New Publication: Hygiene aspects of urine drying technology

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.

Emerging solutions to the water challenges of an urbanizing world

How do we tackle the unprecedented increase in nutrient emissions in the world? How much nitrogen is emitted by agriculture and wastewater treatment? In her presentation at SLU, Professor Tove Larsen from EAWAG, Switzerland analyses the current wastewater treatment situation in various regions in the world. She suggests urine source separation can be part of the solution to address global nutrient emissions. To know more about this and other aspects such as the Blue Diversion Toilet and the Eawag water hub, check out Prof. Larsen’s presentation.Post published by Prithvi Simha

Improving wastewater treatment plants for increased nutrient recovery

Dr. David Gustavsson, Research Leader at Sweden Water Research loves centralized wastewater treatment plants! He starts his presentation saying…“I really love these plants”. At a symposium filled with people discussing the possibility of taking sanitation off the grid, that’s quite a statement to make. Jokingly, he further comments, “....should I leave now?”. How good are centralized WWTPs in removing unwanted substances? In nutrient removal and recovery? Is there a case to be made for the co-existence or indeed, the integration of urine diversion with the operation of such plants? How will WWTP operations be affected with increased urine diversion at source?

Urine Diversion in Durban – Has it exceeded the original vision?

The eThekwini Municipality in the greater Durban region with its 80,000 urine diverting toilets is often highlighted as a success story for dry sanitation. In a recent presentation at SLU, Professor Chris Buckley, Head of the Pollution Research Group at the University of KwaZulu-Natal, South Africa reflected on the eThekwini case study.
