A flotation apparatus comprises essentially a parallelepipedic tank disposed horizontally and provided along its major axis with open-top, potlike injectors for the liquid to be treated with another liquid saturated with gas under pressure. The liquid to be treated is delivered through the bottom and preferably centrally of each injector, and the treatment liquid is supplied through a lateral, eccentric but non-tangential pipe. Siphonal means are provided along the major side walls of the tank and are adapted, in conjunction with the injectors, to create outward and downward fluid flow passing under the siphonal means, other means being provided for removing the top sludge from one end of the tank. |
