What evidence exists related to soil retention of phosphorus from On-Site Wastewater Treatment systems in boreal and temperate climate zones? A systematic map protocol
Environmental Evidence, 2020Co-Authors: Ida Envall, Fritjof Fagerlund, Lena Johansson Westholm, Charlotte Åberg, Arvid Bring, Magnus Land, Jon Petter GustafssonAbstract:Background Soil-based On-Site Wastewater Treatment systems (OWSs) are suspected to contribute to eutrophication of surface waters, due to the discharge of phosphorus (P). However, along the flow path between the facilities and surface waters, different processes contribute to delay the transport of phosphorus through the ground. This may reduce the unwanted impact on receiving water bodies. However, the strength and significance of this so-called soil retention remains unclear.In Sweden, there are nearly one million OWSs. To protect surface waters, a high P removal rate (up to 90%) is often required by the local municipalities. However, since these requirements may have costly consequences to property owners, it is debated as to whether they are too strict. In this debate, it is often claimed that the retention of P occurring in natural environments may be underestimated by authorities. Accordingly, there is a need for a scrutiny of the available evidence related to soil retention of phosphorus from OWSs. This is the objective of the planned systematic map. Focus will be on boreal and temperate climate zones.Methods Searches will be made for peer-reviewed articles and grey literature using bibliographic databases, search engines, specialist websites and stakeholder contacts. The references will be screened for relevance according to a predefined set of eligibility criteria. At stage one, after testing and clarifying the eligibility criteria, the references will be single-screened based on title and abstract. At stage two, potentially relevant references will be screened in full-text independently by two reviewers. We will compile a detailed database of the relevant studies. Moreover, a narrative report will be produced, describing the research landscape in general terms. This will be carried out with a conceptual model, describing the processes involved in P retention in natural environments, as a foundation. It will be discussed where the respective studies/study types fit into the conceptual model, and also evaluated how each study/study type can be related to the overarching question of eutrophication. Moreover, we will describe identified knowledge gaps that warrant further primary research effort, as well as identified knowledge clusters that could be suitable for systematic reviews.

phosphorus sorption capacity of filter materials used for on site Wastewater Treatment determined in batch experiments a comparative study
Journal of Environmental Quality, 2009Co-Authors: Victor Cucarella, Gunno RenmanAbstract:Increasing numbers of filter materials have been proposed as suitable media for P removal in On-Site Wastewater Treatment systems. The phosphorus sorption capacity (PSC) of the material can be estimated in batch experiments and is commonly used as the criterion for material selection. However, there is no standard procedure and batch experimental parameters are arbitrarily established, thus leading to difficulties in comparing the results. The main parameters affecting the batch adsorption system are the form and amount of material, material-to-solution ratio, nature, pH and initial concentration of P solution, contact time, agitation, and temperature. This paper critically reviews a number of relevant studies that used batch experiments to estimate the PSC of different filter materials. The nature and form of the materials vary significantly and there is broad variation in the batch experimental parameters set in the selected studies. Analysis of the data from selected studies showed a relationship between particle size or pH of the material and its PSC. The initial P concentration of the solution and the material-to-solution ratio in the batch system were found to be correlated with the estimated PSC, suggesting that batch parameters have a great influence on the results. Based on the analysis of the selected studies, the difficulties of using batch experiments are outlined, recommendations for batch experiment procedure are suggested and a classification system for filter materials according to their PSC and particle size is presented.

substrates for phosphorus removal potential benefits for on site Wastewater Treatment
Water Research, 2006Co-Authors: Lena Johansson WestholmAbstract:A large number of substrates potential for removal of phosphorus (P) in Wastewater has been reviewed. The substrates consist of natural materials, industrial by-products and man-made products. Most substrates have been investigated in batch and column studies in the laboratory; others have also been tested in field trials. The results from these investigations vary, but a few substrates, e.g. wollastonite, slag material and, to some extent, light weight aggregate products, have demonstrated promising properties with regard to P-sorption capacity and hydraulics. The problems of normalisation of data are discussed, as well as the substrates potential benefits for On-Site Wastewater Treatment.
