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.

New Sjölunda – bromate formation and regeneration of GAC

Some, often coastal, wastewater treatment plants (WWTPs) may have some intrusion of seawater which increases the bromide content of the wastewater, which is/may be problematic in ozonation for removal from organic micropollutants as the by-product bromine, which is harmful to aquatic organisms, is formed. An alternative to ozonation is granular activated carbon (GAC), which is a more expensive process and it largely depends on a regeneration need of the activated carbon. VA SYD has received a grant from the Swedish Environmental Protection Agency to investigate bromate formation during ozonation and regeneration of GAC.

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.
