composition for the treatment of waste containing colloidal dispersions comprising polar solvatate particles and process for the removal of these substances which uses this composizionand

摘要

the invention relates to a composition and a process that uses according to which it is possible to remove the polar development, economically and easily.colloidal dispersions comprising particles solvatate.the composition is characterized by a recess, at a concentration of montmorillonite indicated in a part of the same and sewage treatment to treat.the fraction of and sewage treatment will, or will be conditioned to obtain a ph between 5 and 9. the montmorillonite is then left to "activate selectively, in suspension for at least 1 hour.the method uses the composition provides for this, after the selective activation of montmorillonite.is added under agitation to the remaining and sewage treatment to treat (whose ph is, or should be determined to be larger, 2.5) to obtain a final concentration as indicated montmorillonite. continuing to shake is the precipitation of substances solvatate agglomerated to montmorillonite.for filtration, for example, is quickly filtered clear and a residue formed by the montmorillonite and particles from forming the colloidal dispersion.
