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 […]

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 […]
