A treatment plant for landfill leachate was created in 1997 in connection to Gärstad waste treatment plant near the town of Linköping, Östergötland, Sweden. The treatment plant consists of one aerated outlevelling basin (former clay pit) and three constructed ponds. The ponds are 0.3 m in the first half (to keep oxygen in the water) […]

Water quality improvements for catchment areas are optimal if they take into account local variation in geophysic, hydrologic and economic conditions. A model is developed which uses a series of matrices to describe local variation with respect to ecological and socio-economic variables. This model may be used by catchment based interest groups to evaluate and […]

Research on flow dynamics is believed to open ways for increasing the capacity of the Dissolved Air Flotation (DAF) process in water and wastewater treatment. The paper describes a study on the flow dynamics at Lund Institute of Technology in Sweden. By using an Acoustical Doppler Velocimeter (ADV) flow structures were determined in a pilot […]

Re-use options for sewage sludge are being developed since the disposal of sludge is becoming an increasing problem. The spreading of sewage sludge on agricultural fields as a phosphorus (P) fertiliser is one such option given that it fulfils the requirements for limitation values for metals/toxic substances. The plant availability of P in sludge has […]
