Tiivistelmä
The problem of lake eutrophication is a phenomenon observed around the World. A large number of nutrients enter water body due to both natural environmental factors and human activities, and gradually changing water lakes from poor nutrient status to high productivity in the eutrophic state.
In this thesis, aluminium sludge from the flocculation process (Kuopion Vesi Oy) was used as a low-cost adsorbent for phosphorous removal from lake water. Adsorption kinetic tests were conducted to analyse the adsorbent capability for phosphorous removal from the aquatic solution under various conditions. Experiments were carried out in the lab-scale, and the effect of adsorbent dose, the initial concentration of phosphorus and solution pH on phosphorus process efficiency was investigated.
