Popis:	The suspended solids separation is an essential element in almost any wastewater treatment system. If sedimentation, dissolved air flotation and filtration are compared, flotation has both the largest operational ranges concerning influent suspended solids concentration and particle size, and load bearing capacities. When considering the suitability of flotation as a wastewater treatment process, important factors are the effluent and sludge qualities, operation and costs. To get a comprehensive conception of flotation, those factors are presented and discussed. Flotation is widely used in forest industry wastewater treatment, as well as in process water recirculation. It is also proven technology in foodstuff industry wastewater treatment. Several cases from both industries are presented.
