Water area depollution is accelerated by additionally introducing quinone derivatives into the polyacrylamide with said microorganisms cells immobilized therein.
  • Said water area polyacrylamide depollution method is economically inefficient and insufficiently practical for open water areas; furthermore, petroleum product depollution leads to water area pollution with polyacrylamide hydrolysis products.

  • Disadvantage of said method is the suitability of the suggested sorbent composition, which includes components having different specific weights, mainly for stationary applications, e.g. for sewage crude oil depollution.
  • Zeolite addition to the sorbent is not recommendable for water area surface crude oil depollution as zeolite does not have positive buoyancy will sink thus preventing water surface depollution.
  • (RU Patent 2112594) a method of sewage and water area surface depollution from crude oil and petroleum products by exposing the polluted water to a sorbent comprising peat in a quantity of 90-95 wt.%, zeolite in a quantity of 4-8 wt.% and a mixture of anionic and non- ionic surfactants in a quantity of 0.5-1.5 wt.%.

  • Another disadvantage is the highly labor consuming sorbent modifier preparation procedure comprising the extraction of humic acids from the peat and bivalent metal salts from the sapropel for further mixing thereof to form a gel-like humic acid salt of a bivalent metal, making the sorbent quite costly.

  • Disadvantages of said method are the difficulty of collecting crude oil and petroleum product impregnated cotton industry waste from the water surface if the sizes of their balls are small, the complex equipment and process required for the utilization of crude oil and petroleum products that impregnate separate cotton industry waste balls during water surface depollution, the relative low sorptive capacity of cotton industry waste for crude oil and petroleum products (7 g oil per 1 g cotton waste) and the insufficient available quantities of cotton industry waste for crude oil and petroleum product spill response (up to 1 mln. tpy).
