METHOD FOR FLOTATION PURIFICATION OF SOLUTIONS FROM DISPERSED PARTICLES Russian patent published in 1995 - IPC

FIELD: water treatment. SUBSTANCE: air is mixed with particles of surfactant soluble in treated solution, and produced mixture is ionized in the field of corona discharge. Charge polarity of ionized mixture of surfactant particles and air molecules is taken opposite to polarity of charge of dispersed particles to be removed. Produced mixture after ionization is introduced into flotation chamber with solution to be cleaned, with subsequent removal of separation products. Surfactant is used in form of anionic, cationic and ampholitic types. EFFECT: increased degree of purification and accelerated process. 2 cl, 1 dwg
