FIELD: chemistry.
SUBSTANCE: to perform purification flocculant is introduced into technological water; stoichiometric polyelectrolyte complex based on cationic polyelectrolyte - N,N,N,N-trimethyl[metacryloiloxyethyl] ammonium methyl sulphate, and oppositely charged detergent - "Volgonat-emulgator", derived from Na-alkyl sulphonate, is used as flocculant. Complex is formed after introduction of polyelectrolyte in two equal portions: at the first stage non-stoichiometric water soluble polyelectrolyte complex is formed, at the second stage stoichiometrical polyelectrolyte complex is produced.
EFFECT: the method allows to simplify purification technology, to speed up precipitation of impurities and to increase clarification level.
