ABSTRACT:
An apparatus for removing harmful substances from effluents has two chambers located symmetrically at opposite sides of an effluent channel. Each chamber contains two or more stacked trays which are each provided with a spiral flow path descending from a tray inlet to a tray outlet. All tray inlets are so located in the channel that substantially all effluent flowing in the channel is compelled to enter them and to travel by gravity through the respective tray. Air, an insert gas or a mixture of both is bubbled from below through the effluent flowing in the trays to expel and entrain the harmful substances. The treated effluent is then discharged back into the channel at locations downstream of its point of admission into the inlets.
