FIELD: equipment for purifying of water from petroleum products, fats and surfactants.

SUBSTANCE: flotation apparatus has case made rectangular in plan and provided with paired partition walls. Perforated pipelines for supplying of air-and-water mixture, froth removal mechanism with froth collector, and unit adapted for discharging of waste water and equipped with receptacle pocket are mounted between partition walls. Stepped baffles are disposed on partition walls above perforated pipelines. Stepped baffles are made wedge-shaped or truncated wedge-shaped. Bases of wedges or truncated wedges are aligned with surfaces of partition walls. Lower faces of wedges are perpendicular to axes of openings of perforated pipelines so that stream strikes against lower step of baffle.

EFFECT: increased efficiency in purifying of water provided due to production of small air bubbles and uniform saturation thereby of water under treatment procedure.
