The issue of treating wastewater system of metallurgical and heavy metal compounds industries has been increasingly paid more attention in ecology system nowadays. The study assessed the effect of adding surfactants or flocculants to the wastewater system with the efficiency of electroflotation extraction of metals from aqueous media. It has been founded that the addition of flocculants (cationic/anionic/nonionic) can increase the purification efficiency by 1–3% for all systems under study, regardless of the anionic composition of the water being treated. The addition of cationic and anionic surfactants has not effected significanty on the purification process, but the addition of a nonionic surfactant significantly inhibits the flotation process.
