Abstract: Method and flotation vessel for removing contaminants from aqueous fibrous suspension. Method includes damming up fibrous suspension at head level above base of flotation vessel, forming a bubble flow of gas bubbles rising counter to field of gravity in dammed up fibrous suspension, and guiding fibrous suspension crosswise to bubble flow, such that as contaminants are deposited on gas bubbles to form thickened flotation foam, fibrous suspension is cleaned. Method also includes discharging cleaned fibrous suspension as accepts, and discharging thickened flotation foam. A flow cross section of flotation vessel lying crosswise to bubble flow is straight on at least 80% of at least one side wall and a length of side wall is at least 1.5 times as great as that of an end wall.
