An early method of surface aeration in the activated sludge process, devised by Dr H.H. Kessener of Holland in 1925, with rapidly rotating stainless steel brushes on a horizontal shaft. The brushes are partly submerged in the mixed liquor, swirl it around and thus aerate it. It has been superseded by the TNO rotor.

Les rotors ont en général 2,5 m de longueur, correspondant à environ 400 m[carré] de capacité du chenal d'oxydation, capable de desservir 1 200 à 1 500 habitants.
