Process for treating liquid manure, comprising the introduction of
homogenized liquid manure into a tank, into which are introduced some
polymers/copolymers that bring about an interchange to produce the
flocculation of colloidal substances and solids in suspension, which are
then separated off with the aid of filters. The flocculation is carried
out by feeding the liquid manure in at a constant flow rate and
introducing the reagent at the same time in the form of a tertiary or
quaternary polymer/copolymer, stirring the mixture for a time of between 5
and 15 minutes and then eliminating the suspended solids by flotation,
involving the coalescence of the colloidal particles.
