21. Sewage Sludge Treatment Scenarios: Techno-Economic Analyses of Energy and Phosphorus Recovery Focusing on Implementation Challenges
Sammanfattning : .... LÄS MER
22. Phosphorus release and recovery from treated sewage sludge
Sammanfattning : In working towards a sustainable society, recycling and recovery of products together with handling of scarce resources must be considered. The growing quantities of sludge from wastewater treatment plants and the increasingly stringent restrictions on landfilling and on agricultural use of sludge are promoting other disposal alternatives.

24. Analytical method development for ultra-trace determination of human pharmaceuticals in aqueous samples. Assessing the performance of a sewage treatment plant
Sammanfattning : Research focus in environmental pollution has recently been extended from more classical environmental pollutants such as PCBs or pesticides to pharmaceuticals and steroid hormones, which are designed to be biologically active and enter the environment primarily through regular domestic use. Consequently, it is important to monitor these substances concentrations in the effluents of sewage treatment plants (STPs) and in the environment in order to evaluate their associated risks. LÄS MER
25. An add-on filter technique to improve micropollutant removal and water quality in on-site sewage treatment facilities
Sammanfattning : Onsite sewage treatment facilities (OSSFs) in Sweden currently release significant amounts of nitrogen (N) and phosphorus (P) into groundwater or/and receiving water bodies. Micropollutants (MPs) have been found in both surface water and groundwater, indicating insufficient removal of MPs by OSSFs. LÄS MER
