Abstract RU 2231499 C2

FIELD: waste water treatment.

SUBSTANCE: aerator for biological treatment of waste waters contains dispersing element, in particular porous shell made from polymeric material and formed by randomly laid fibers melted together in their intersection points. Density of porous shell ranges from 3.5·10² to 6.1·10² kg/m³ and its thickness from 3 to 9 mm. Shell density and thickness values vary from low limits to high ones according to the shell cross-section profile.

EFFECT: enabled various degrees of air dispersion over the aerator surface.
