FIELD: physics.
SUBSTANCE: invention can be implemented for biological sewage treatment in aerotanks with activated sludge. Tubulat bubble aerator comprises support tube 1 with radial holes 2 and dispersing coating 3 with variable porosity and pore size. Pores in dispersing coating are arranged in spirals because the coating winds in each next layer are displaced half a thread diameter from the previous layer. This ensures that air bubbles escape tangentially to the aerator surface.
EFFECT: improved efficiency of wastewater aeration and increased liquid bubbling.
