Abstract [en]

On-site sewage facilities (OSSF) in Sweden were investigated to check the treatment function and determine the potential for removing micropollutants (MPs). The 16 OSSFs studied included soil filtration systems (SFS), package treatment systems (PTS) and source separation of sewage (SSS). Two medium-sized municipal wastewater treatment plants were also included for reference. Nitrogen (N), phosphorus (P), dissolved organic carbon (DOC) and MPs were analysed. For SFS, overall removal efficiency of nitrogen and phosphorus was acceptable, but some individual facilities showed poor treatment results. This was generally attributable to lack of maintenance, which affected removal performance for most parameters tested. No-target screening for MPs, carried out in laboratories at Umeå University (UU) and the Swedish University of Agricultural Sciences (SLU), revealed average removal efficiency of 52.4% for SFS and 37.5% for PTS. Thus MPs can be removed by on-site sewage systems, but higher removal efficiency is needed.
