- Wastewater with high concentrations of nutrients, pathogens and many micro-pollutants is usually satisfactorily treated by application of technologies which employ chemical processes. However, due to the absence of these processes in most small-scale wastewater treatment (SWT) systems, pollutants often escape treatment and ultimately end up in water bodies, hence the persistence of eutrophication and waterborne diseases experienced in many parts of world. Due to the recent introduction of requirements for SWT systems to comply with national discharge standards, alternative effective technologies are needed. Among the wide spectrum of supposedly effective alternative technologies which have been developed to-date, some can be incorporated to extend treatment chains of ineffective SWT facilities, e.g. package treatment plants and wetlands, while others are designed to enhance processes in some treatment steps, e.g. bioreactors for pre-treatment. However, due to the high costs, complexity and scarcity of many of these advanced technologies, reactive filter (RF) media are seemingly preferred. Much current knowledge about the potential of RF media is based on batch and column experimental findings. Therefore, various aspects of RF media relating to performance in full-scale plants are generally unknown. To our knowledge, no previous study has outlined the importance of key parameters distinguishing the performance of different RF media in full-scale plants or suggested the use of versatile media. This study therefore acquired and compiled data on RF media previously tested in full-scale plants, to compare and highlight parameters relating to their potential in treating wastewater of different strengths.
