MIXER FOR WATER TREATMENT PLANTS WITH OPEN CHANNEL AND TREATMENT OF WATER USING ULTRAVIOLET RADIATION

摘要

FIELD: treatment plants.SUBSTANCE: invention relates to a mixing device for water treatment plants with an open channel. Device comprises base (2) in form of a plate or strip to be attached to channel wall so that during operation lower surface (6) of said main part faces channel wall, and upper surface (5) faces away from channel wall. Device also comprises multiple protrusions (3) extending from base (2) from lower surface (6) and extending over plane formed by upper surface (5), and a plurality of corresponding recesses (4) located between two protrusions (3).EFFECT: invention enables to optimise radiation acting on jet flow along edge in systems with rows of ultraviolet emitters shifted relative to each other.11 cl, 3 dwg
