This work presents results from a sedimentological investigation of Lake Södra Bullaren, Sweden, and a budget suspended matter for the lake. The basic question concerns the spread offeed wastes and faeces from a fish farm. Where do these emissions appear? Are they large in comparison to other fluxes of marerial causing increase in total-phosphorus-concentrations and […]

This lake has been the focus of an agitated debate because there is a fish cage farm for rainbow trout in the lake, which has been accused of “ruining“ the lake. LEEDS […]

A GIS-based database for PC-use in a MS-Windows environment has been developed in order to ger a clear piciure of the present status of problems and information handling on coastal erosion problems in nine communities in southern Sweden (Båstad, Angelholm, Helsingborg, Lomma, Vellinge, Trelleborg, Skurup, Ystad and Simrishamn) coupled with actual remedial measures taken.

Aerobic thermofilic digestion (liquid composting) is an autothermal sludge stabilisauon process that normally operates at temperatures higher than 50°C. The process requires electric power for mixing and aeration. Otherwise, the technique is simple and reliable. A treatment plant which is properly designed and operares at high remperature produces a sludge that is stabilized, odourless and […]
