Implementing Urine Drying technology in Durban, South Africa

Prithvi Simha, Jenna Senecal, and Björn Vinnerås just returned after spending a week in Durban, South Africa. We travelled there to present our novel sanitation technology called alkaline urine dehydration to several potential collaborators, and to see if the technology could fit into the local context. We met with sanitation experts from the Pollution Research Group at the University of KwaZulu-Natal, the eThekwini Municipality, and Envirosan (a toilet manufacturer based in Durban). The trip was extremely fruitful with a positive response from all experts about our technology. We even brought back with us two new urine-diverting toilets to test our system with (thank you Envirosan!). Our next step will be to return to Durban with a pilot-scale urine drying system that the Pollution Research Group will test at their research facility. Following this, drying units will also be tested in people’s homes at the eThekwini municipality. A big thank you to Chris Buckley for co-ordinating the trip & to the NJ Committee on Global Affairs for the financial assistance.SLU EnviroSan Loot; PC: Chris Buckley

Framtidens avloppssystem workshop Monte Verita, 14-17 mars

Björn Vinnerås deltog i detta möte på ETHs kursgård Monte Verita i Ascona i södra delen av Schweiz. Platsen var en av de mer bildsköna mötesplatser man kan tänka sig med palmer i förgrunden och snöklädda berg i bakgrunden. Utsikten från konferenscentret Monte Verita. PC: Björn Vinnerås

Fokus Deltagarna i mötet var 35 internationella experter omkring decentraliserad sanitet. Fokus för diskussionerna var framtidens enskilda avlopp med ett specifikt fokus på lokala lösningar. Bernhard Truffer, EAWAG presenterar skillnaden i kostnad mellan centralicerade och decentraliserade system i relation till antalet användare i Schweiz.

New study on occurrence and concentrations of PFASs in Uganda

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  concentrations and partitioning of 26 per- and polyfluoroalkyl substances (PFASs) in wastewater, surface water, soil and crop plants (yam, maize and sugarcane) in Nakivubo wetland and Lake Victoria at Kampala, Uganda.Location of the study area at Kampala, Uganda, and the sampling sites

SPANS project work in Uganda

There is a lot going in the SPANS project in Uganda right now.

We have started demonstration units of nutrient-recovery treatment technologies for fecal sludge at the Luibgi wastewater treatment plant in Kampala. Two MSc students from Luleå University of Technology are currently operating demonstration units for treatment with lime and urea.  The students are collecting and analyzing samples to determine if the technologies are functioning properly with regard to reduction of public and environmental health risks. They are also doing interviews with workers at the wastewater treatment plant and other stakeholders to understand the levels of acceptance and feasibility of implementing such technologies within the existing management structures. Soon two students from Makerere University will be starting a demonstration unit with Black Soldier Fly composting at the wastewater treatment plant.

Professor Håkan Jönsson får Vatten-priset

On March 14th, Professor Håkan Jönsson will be awarded the Water Prize by Föreningen Vatten (Society Water). ”Never during my 10 years in the board of Föreningen Vatten have we received so many heavy nominations for a certain person. Most universities, organizations and individuals in the industry have shown strong support for this prize winner”, writes Marta Ahlquist-Juhlén, the chairman of Föreningen Vatten.

Among others, Prof. Jönsson has actively worked to close the cycle between cities and rural areas for 25 years, and his research has made a great impression. Most well-known is his commitment to upstream solutions in wastewater systems and his work on recycling plant nutrients from wastewater to arable land.

The Future of Sanitation Education

At a symposium hosted by the Kretsloppsteknik group, Dr. Mariska Ronteltap of the IHE Delft Institute for Water Capacity Building presented her perspective on what the future of sanitation education could look like. Why is it important to build capacity in the WASH sector? How can we do it through innovative teaching methods? How can MOOCs, Online Learning, Professional Diploma Programs, Active Learning, etc. towards sanitation education? Learn about this and the one-year Masters Programme in Sanitation being developed by IHE in Dr. Ronteltap’s presentationPost published by Prithvi Simha

Source separation: the future for efficient resource recovery

What is ‘New Sanitation’ according to Professor Grietje Zeeman from Wageningen University in the Netherlands? How has the practical experience been so far with the upflow anaerobic sludge blanket (UASB) reactor for blackwater treatment and bio-flocculation of greywater? Can micropollutants be mitigated through composting of anaerobic sludge? Are heavy metals from wastewater really a problem in agriculture? Interested in learning more about how these technologies have been applied at full scale in Sneek, Venlo, Wageningen and The Hague?

Sustainable technologies to meet the future needs for sanitation

Is it possible to reduce the water footprint of a city to 1/10th of its current value without sacrificing any comfort? What does circular economy mean for sanitation systems? How important is phosphorous for food production? How can source separation systems improve nutrient cycling in the environment? Can we produce biodiesel from algae grown in urine? Professor Petter Jenssen from the Norwegian University of Life Sciences explores these questions and many more in his presentation which can be accessed herePost published by Prithvi Simha

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
