A water purification plant and method for purifying liquid by flotation clarification, in which pollution particles, or impurities dissolved in the liquid and brought into a particle form by flocculation chemicals, are separated from the liquid and led onto a surface of the fluid to form a bed of slurry. The slurry bed is led away into a sewer system and the purified liquid is led through an intermediate bottom of a clarification basin into a lower space of the clarification basin or directly away for additional purification or consumption. The intermediate bottom of the clarification basin is provided with elements affecting the flow such that the flow resistance occurring through the intermediate bottom is at its largest at the final end of the clarification basin and the flow resistance decreases towards the initial end of the clarification basin, whereby the entire area of the clarification basin has substantially the same, and uniform, flow volume.
