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… Continue reading Emerging solutions to the water challenges of an urbanizing world
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… Continue reading Improving wastewater treatment plants for increased nutrient recovery
The Future of Sanitation – a return to circular systems
Is urine diversion a new concept? In his presentation at SLU, Jan-Olof Drangert, Assoc. Prof. at Linköping University traces the evolution of sanitation and nutrient recycling in Sweden over the years. He suggests that, water-based sanitation used in the 20th century may have been just a brief detour in human history as we’ve strongly relied… Continue reading The Future of Sanitation – a return to circular systems
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. Curious to know whether or not… Continue reading Urine Diversion in Durban – Has it exceeded the original vision?
How to get the best value out of organic waste?
Municipalities are expected to provide solid waste management to their inhabitants, funded by tax revenue or/and waste treatment fees. In many low and middle income countries, municipalities however struggle to provide an adequate level of service; in such places the informal sector plays a major role in the collection and treatment of solid waste. In… Continue reading How to get the best value out of organic waste?
Hur fås högsta värdet ur biologiskt nedbrytbart avfall?
Kommuner förväntas tillgodose sina invånare med avfallshantering, vilket finansieras med skatteintäkter och/eller avfallshanteringsavgifter. I många låg-, och medel-inkomstländer kämpar kommunerna med att tillgodose en acceptable servicenivå och på dessa ställe sköter den informella sektorn ofta stora delar av insamlingen och behandlingen av avfallet. Till skillnad från plast-, och metallfraktionerna, sköter inte den informella sektorn om… Continue reading Hur fås högsta värdet ur biologiskt nedbrytbart avfall?
Research shows Biochar is efficient in removing pharmaceutical residues at onsite sewage facilities
In a very recent study published in Science of the Total Environment, Sahar Dalahmeh, a researcher at the Environmental Engineering Unit, and her co-workers investigated the potential of biochar filters to replace or complement sand filters for the removal of pharmaceutical residues from wastewater in onsite sewage facilities.
