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

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

Advantages over analogues: Conducting patent-infomatsionnyh Search by country United States, Germany, France, Japan, showed 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 some of them completely eliminate the effect to reduce the concentration of surfactants in water to 100-150 mg / cubic dm . to 2,0-5, 0 mg / dm cube. For the implementation of the proposed general description of the method of foam fractionation, 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 an expenditure in the amount of - 90 thousand $.

Description of the development:
()
Based on the improvement of colloid-chemical model of ionic surfactant removal of flotation-active substances developed a method (variant flowsheet) their flotation withdrawal - foam fractionation. For removal of dilute aqueous solutions of surfactants (industrial wastewater) must pass through them air bubbles formed collect foam destroying it. However, the solutions are removed from the suspended, emulgirovannye substance therein. 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 rubles. Per year) et al. the enterprises of Ukraine and Russia.
