This method was founded on combination of flotation and extraction methods which is based on transmission of gas bubbles through the aqueous phase and passing pollutant substances (sublate) into organic phase. Organic phase must be lighter then water and must not dissolve in it. Solvent sublation has such advantages as possibility of multiple pollutant ions concentration in small volumes of organic solvent; possibility of valuable components regeneration; much smaller amount of organic solvent is used (compered to extraction method); process is not limited by the distribution constant; absence of foam (compared to flotation); less wet sludge [1].
