Abstract
The present invention concerns a procedure for purifying in a fluidized bed reactor (1) effluent waters, particularly those produced in the wood-processing industry. The reactor contains, in addition to fluidized, finely divided particles (7), also agglomerated fibre material (8) serving the purpose of reducing the quantity of the floating particles required. The fibre material may for instance be cellulose, introduced in the reactor together with the effluent water to be treated and which is converted into agglomerates in the reactor.
