Treatment of source separated greywater for lower effluent requirements with MBBR and Horizontal Filters
This is Ashley Hall’s doctoral thesis. Ashley is an industrial doctoral student from Sweden Water Research through 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.

The untapped potential of greywater: Decentralised treatment and use for blue-green public spaces
Sweden also has a water shortage some summers. In 2018, more than 80 municipalities needed to introduce restrictions on water use. With source-sorting sewage technology, the possibility of using greywater for irrigating green areas is opened up.
Increased production of biogas through industrial symbiosis – co-digestion of steam pretreated straw and sewage sludge
Straw has an untapped potential for domestic biogas production of at least 4.3 TWh.
Characterisation of municipal wastewater
Major investments will be required in the next few years to deal with aging infrastructure, population growth, urbanisation and new emission requirements at municipal wastewater treatment plants (WWTPs). These investments are preceded by evaluation, design and optimization, which in turn require access to good data to provide security in the decisions made and to ensure cost-effective solutions.
Sewage sludge spreading on arable land – PFAS in sludge, soil, crop and earthworm
Is the use of municipal sewage sludge on arable land a spreading route for PFAS?
Residues to best use – biochar as solution and product in the circular and climate positive society
Pyrolysis of dried sewage sludge generates a sludge biochar that can be used in several applications. VA SYD participates in the project Residues to best use to increase its knowledge about biochar and its possibilities.
Poster competition for students to raise awareness about microplastics in Gdansk
Gdańsk Water Utilities (GIWK) has been active in providing the residents of the City of Gdańsk with the ecological education for years. The related activities are led under ecological programme named „Hydromission” that aims to raise public awareness on environmental protection issues.
REWAISE
REWAISE is one of five innovation projects supported by the Horizon 2020 framework program. The goal is to reduce the use of drinking water and use water in a smarter and more efficient way.
Digital twin for sustainable and resource efficient operation of wastewater treatment plants
Within this project, a method for developing digital twins at WWTPs will be developed, including real time process simulation and data validation.
Measurement of direct greenhouse gas emissions from wastewater treatment basins
Climate neutrality in the water and wastewater business can only be fulfilled if emissions of methane and nitrous oxide are low. We need good methods to identify and quantify these emissions and this project will work with establishing a methodology to measure and identify hot-spots for these emissions.
Källby Water Workshop, Lund
Källby Water Workshop is an innovative test bed and an arena where companies, universities and utilities can work together to develop the future measurement methods for drinking water quality.
Educational activities – a vehicle for meeting future recruitment needs?
In this project, doctoral student Laura Giese is looking into how effective the educational activities are and how they can be developed to attract both boys’ and girls’ interest in a career within the water sector.
