Environmental Measures

The Water Framework Directive (WFD) focuses on reduction of nutrients in individual water bodies. Innovative drainage filter technologies currently being tested in Denmark could facilitate nutrient reductions at the sub-river basins and catchment levels. The implementation strategy for these technologies, however, remains a challenge. Using both primary and secondary data, this paper presents an in-depth analysis of the role of these technologies in implementation of the WFD in Denmark. Concepts of impact assessment are used to identify the most suitable approach for incorporating these technologies into environmental measures based on a three-faceted policy instrument typology. A voluntary approach supported by investment subsidies, or incentives that could replace existing requirements, is deemed more appropriate.

Improve Water Quality

Artificial floating islands (AFIs) are a variation of wetland treatment systems for water quality improvement. This paper provides a review concerning AFIs in terms of their development, classification, and applications in the removal of nutrients, heavy metals, and chemical oxygen demand on waterways. The role of microorganisms, aquatic plants, and aquatic animals in AFIs for water decontamination and purification was also discussed. Additionally, some key factors influencing the AFIs’ performances were discussed and comparisons between AFIs and constructed wetlands were reviewed. Finally, further perspectives of artificial floating islands were identified to possibly improve their performances. The understanding of the mechanisms in AFIs that drive removal of various contaminants to improve water quality is crucial, and is also highlighted in this paper.
