Industrial ecology tools as decision – making aids for sustainable phosphorus recovery – a methodology paper / Industriell-ekologiverktyg som beslutsstöd för hållbar fosforåtervinning – en metodartikel
India, being the second largest importer, and the largest consumer of phosphate fertilisers in the world, needs to focus on securing its supplies not merely by providing subsidies to importers but also focusing on recovery and recycling of phosphorus from waste streams. In the process, the country can avail of concomitant benefits like wastewater reclamation […]
Microsieving coupled with O3 or ClO2 for treatment and disinfection of combined sewer overflows / Mikrofiltrering i kombination med O3 eller ClO2 för behandling och desinfektion av bräddvatten
A compact combined sewer overflow (CSO) treatment unit is set up and evaluated in pilot-scale. The pilotplant consisted of flocculation, coagulation and a microsieving system followed by a disinfection unit with either O3 or ClO2. Efficiency of the pilot-plant was evaluated with respect to reduction of Escherichia coli, coliform bacteria and intestinal enterococci as well […]
The possibility to implement artificial recharge at Kristianstadsslätten in south of Sweden / Möjligheter med konstgjord grundvattenbildning i Kristianstadsslätten i södra Sverige
The Kristianstadsslätten plain is located in south of Sweden and holds one of the largest aquifers in the country. Kristianstadsslätten has been of greatest importance for groundwater abstraction and an ever-increasing desire to intensify the groundwater abstraction exists. The aim of this paper is to determine if it is possible to implement artificial recharge at […]
Water pinch analysis – a review of recent journal publications / Vatten-pinch analys – en översyn av de senaste publikationerna
As the population of the world increases, the demand for resources of different types will also grow. Water is one such resource. Pinch analysis, as a technique to optimise the utilisation of resources, had its origin in heat recovery and thereby the optimisation of fuel usage in the 1970s during the oil crisis. Since then, […]
Markbaserad rening – en studie av funktion i fält / Soil-based wastewater treatment – a field study
Soil-based wastewater treatment, i.e. septic tanks followed by an infiltration or a sandfilter bed is the most common solution for small scale wastewater treatment in Sweden. In this project four students have surveyed 217 households in a field study. Grab samples have been taken on both suspended solids from the septic tank and on the […]
Multikriterieanalysverktyg vid bedömning av framtida dricksvattenförsörjning / Multi-criteria analysis-tool for assessing future drinking water supply
In this work, a multi-criteria analysis (MCA) method has been developed for evaluation and comparison of alternative drinking water strategies. A selection process of options was proposed and three options for weighting purpose were compared. The work includes an introductory literature study for identification of criteria and indicators (K o I) used during assessment of […]
Varför etableras en forskningsstation vid Bolmen? / Why establish a research station at lake Bolmen?
The article presents the initiative behind the Bolmen Research Station in Hylte Municipality, South Sweden, which was initiated in 2017, enabling site-based research, development and innovation on lakes and lake-based activities starting at Lake Bolmen. This lake is the main raw water resource for Skåne. Since 1987, the company Sydvatten has taken raw water from […]
