Abstract

Method for the purification of waste water comprising treatment of the water requiring purification with a water-based dispersion of iron (II and III) hydroxides which is obtained by electrolysis in generators 24 using iron anodes and cathodes in an aqueous medium with an acid and a salt, performing the said treatment in a reactor 10 where precipitation of the pollutants added to the water takes place, with subsequent settling of the sludges in sedimentation tanks 6 where treatment for inerting the sludges by means of temperature and pressurized air is then applied, passing finally through a flow filter 33 to dewater the said resulting sludges. <IMAGE>
