Is biodegradable waste a problem or a resource? Some claim it’s a resource that can be managed in a much more efficient way, but how come it isn’t? How could a more efficient management look like? If you find these questions interesting, come and listen to Cecilia’s lecture. A summary of the lecture, that will be given in English, can be found below.

Chinmoy Deb joins the Urine Drying Project

Published
By

Our former intern, Chinmoy Deb from India, who came to SLU last year for his Bachelor’s thesis on Urine Drying, has successfully received his Bachelor’s degree in Chemical Engineering. Currently, Chinmoy has started his Master’s program in “Soil, Water and Environment” at SLU and has been recruited as a member of our group. During his bachelors’ program, back in India, he had worked with urine for nutrient and pharmaceutical removal. With a keen to connect the nexus of sanitation, hygiene and agriculture, he has joined the group to continue his research on the recovery of plant essential nutrients by means of urine drying technology.

A pilot multi-module biochar filter was built and is running in a household in Gamla Uppsala

Published
By

A demonstration household biochar filter has been built and is now running in a household in Gamla Uppsala to treat wastewater from a single household of 5 person. The filter has a unique design in which the biochar is used as a filter material in a multi module cabinet staked biochar of different properties to remove different types of pollutants including organics and micro pollutants.  During the upcoming period, the quality of the wastewater will be analysed for different parameters (COD, Tot-N, Tot-P and other pollutants).  For more information, please contact Sahar Dalahmeh (Sahar.Dalahmeh@slu.se)

New project: development of analytical methods for extraction, identification & quantification of microplastics in sewage sludge

Published
By

With a generous financial support from eight wastewater treatment utilities in Sweden as well as from Svenskt vatten (via VA-kluster Mälardalen), Sahar Dalahmeh started a research project focusing on development of analytical method for extraction, identification and quantification of microplastics in sewage sludge. Different extraction protocols (acids, base and enzymatic extraction will be tested and optimised). Also, different identification methods will be investigated, not the least these using µ-FTIR for chemical imaging. All the equipment needed for development the method are in place including state of the art Cary 660 IR spectroscopes coupled to 620 Cary FTIR microscope (Agilent Technologies) for micro imaging and chemical scanning microscope. The projects runs during 2019-2021.  For more information, please contact Sahar Dalahmeh (Sahar.Dalahmeh@slu.se)

Sahar Dalahmeh, researcher at the group was invited as a key note speaker in the International Workshop in Water, food and energy nexus organised within the 10th national conference of environmental chemistry in Tianjin in China 16-19th August 2019. In her talk, Sahar highlighted the important potential of using wastewater for irrigation for food production. She also presented her latest results on whether Micro pollutants, such as pharmaceuticals and PFAS can be a risk when wastewater is used for irrigated agriculture.

Kretsloppsteknik at the 3rd IWA Resource Recovery Conference

Published
By

Between 8th and 12th September, Björn and Prithvi were in Venice to take part in the International Water Association‘s 3rd Resource Recovery Conference in Venice. Prithvi had an oral presentation where he talked about the pilot testing of the alkaline urine dehydration technology at Pori Brigade in Finland. At the conference, Prithvi also co-chaired the session on urine valorisation and water reuse, as a Young Water Professional. Since we were shortlisted for the IWA Resource Recovery Award, we also had a poster presentation about Sanitation360 AB, the group’s spin-off company implementing urine dehydration technology.
