PhD project: Removal of organic micropollutants at Swedish WWTPs
This is the PhD project of Maja Ekblad. Maja is an industrial PhD student at Sweden Water Research and Lund University.
Our projects
Sweden Water Research conducts research into water and develops new, effective solutions to meet the future challenges facing the water services industry.
We create, run, participate in and initiate projects that seek out suitable partnerships, with the ultimate aim of increasing knowledge of successful methods for the development and climate change adaptation of the cities of the future. Projects within Sweden Water Research are run in close collaboration with the owner municipalities and will, in either the short or the long term, benefit day-to-day operations.

ÖreWise
ÖReWise's main purpose was to form the basis for the development and implementation of solutions in climate adaptation with a focus on a holistic view for the region.
RörANN
This work kick-started AI (artificial intelligence) for pipe management among Swedish water utilities.
Sustainable management of urban flooding
Urban flooding is an increasing problem, both in Sweden and in the world. One reason is climate change, but the main reasons are that our societies are not designed to handle extreme downpours. It is also unclear which public bodies are responsible for minimizing the risks.
Removal of pharmaceutical residues in aerobic granular sludge and activated sludge – a comparison study in full-scale
Approximately half of the micropollutants in municipal wastewater are removed in wastewater treatment plants (WWTPs) through adsorption or biological degradation. However, the knowledge about this removal is inadequate.
ELSA – Efficient aeration at the Swedish wastewater treatment plants
Previous studies show that the potential to make municipal wastewater treatment plants (WWTPs) more energy efficient is great. The largest energy use at WWTPs is found in the aeration of the biological processes in the wastewater treatment.
Micropollutant removal at Sjölunda WWTP – bromate formation in ozonation and regeneration of activated carbon
During 2021-2022 bromate formation in ozonation and regeneration of activated carbon were investigated at Sjölunda wastewater treatment plant (WWTP) within a prestudy for a rebuild of the wastewater treatment plant in order to meet a growing population. The project was financed by the Swedish Environmental Protection Agency (Naturvårdsverket).
Rational microbial analysis for distribution of biostable quality drinking water
This project investigates the biological status of the drinking water distribution system, with a focus on biostability and measures for securing a stable drinking water quality.
MACRO – Food in circular robust systems, step 3
Source separated wastewater systems enable a circular economy through the return of plant nutrients, reduced water use, reduced energy use, increased biogas production and reduced greenhouse gas emissions.
Run4Life – Recovery & utilisation of nutrients 4 low impact fertiliser
The world food supply is entirely dependent on the use of fertilisers. However, the current fertiliser production practices are not sustainable. Domestic wastewater is an important carrier of resources: especially water, energy and nutrients. In the current centralised wastewater management systems these resources are hardly recovered.
NPHarvest – Sustainable recycling of phosphorus and nitrogen
NPHarvest is a technology, developed by Aalto University, to extract phosphorus and nitrogen from highly concentrated wastewater streams such as digested black water or reject water from the digestion of sewage sludge. The technology has been tested on a pilot scale at RecoLab.
Cultivating urban bazaars – for sustainable, job-creating urban development, step 3
Cultivating urban bazaars is an innovation project whose goal is to build a small-scale, sustainable industry through urban cultivation that creates new jobs and the opportunity to reach out to start-up companies focused on innovative environmental technology.
