Purpose of the development: Designed for removal from dilute aqueous solutions of surfactants (sewage treatment, industrial enterprises).

Recommended application field: Fields of application: chemical, engineering, petrochemical.

Advantages over analogues: Conducted patent information retrieval Country USA, Germany, France, Japan has shown that the essential features of technical solutions development meets world standards.

The development stage readiness: Introduced in production

Technical and economic effect: Method of cleaning industrial wastewater polluted by surfactants, allows to reduce the harmful effect on the environment pollution by 40-50 times, and in some cases completely eliminate their effect to reduce the concentration of surfactants in water with 150 - 200 mg / dm cube. to 1,0-5, 0 mg / cubic dm., reduce processing time, flotation to reduce the amount of foam concentrate that does not exceed 5-7% of the volume of the solution, which was subject to flotation treatment. For the implementation of the proposed method is a general description of the deposited flotation, flotation unit, ecological passport. Development of the purification process, the selection of the most cost-friendly version of the technological scheme of cleaning, building treatment plants (flotation plant) requires the expenditure of - 90 thousand $.

Description of the development:
()
Based on the improvement of colloid-chemical model of flotation removal of ionic surfactants developed a method (variant flowsheet) their flotation withdrawal - sedimentary flotation. For removal from dilute aqueous solutions of surfactants (wastewater industries) should be added to the water reactant osazhivatel, skip through them air bubbles collect formed product (Sublative case). Purification plant, made on the basis of development work on Losino-Petrovsky factory of primary wool processing (city Losino-Petrovsky), an NGO "contactor" in Ulyanovsk (economic effect in prices of 1992 amounted to 860 thousand. Rub. Per year) et al. the enterprises of Ukraine and Russia.
