Abstract
The process of getting clarified denitrified water in a biofilter used combined methods of displacement (piston) biofiltration and bubble-film extraction is studied. It is shown the products of bacterial metabolism released into the water at biofiltration have surfactant properties. They can serve as collectors of the dispersed phase to achieve the desired degree of clarification of water when using bubble-film extraction. The turbidity of the resulting denitrified water does not exceed sanitary and hygienic limits. The concentration of biosurfactants is also significantly reduced.
