LAMELLA FOR CLARIFIER AND LAMELLA MODULE FOR CLARIFIER Russian patent published in 2022 - IPC B01D21/02 

FIELD: purification.

SUBSTANCE: invention relates to the field of purification of waste flows of liquids contaminated with impurities in the form of weighted solid particles; it is used, for example, for purification of wastewater or drinking water by separation of weighted solid particles. In the claim, a lamella intended for use in a lamella clarifier, as well as a lamella module intended for use in a lamella clarifier are described. Lamella (1) for the clarifier is formed by rectangular or square plate (5), upper edge (10a) and lower edge (10b) of which pass in parallel to transverse direction (T), and the rest two edges (15a, 15b) pass in parallel to longitudinal direction (L). The plate is equipped with longitudinal folds (20) bent in longitudinal direction (L) and passing from upper edge (10a) to lower edge (10b) of the plate. Plate (5) is bent in longitudinal direction (L) in such a way that a zone closer to lower edge (10b) of the plate is less tilted relatively to horizontal (H), compared to a zone closer to upper edge (10a). The lamella module contains two or more lamellas installed in parallel without a direct contact with each other and attached to support elements.

EFFECT: increase in the performance of purification of liquids, improvement of indicators relatively to contamination of lamellas, which stay pure during a longer time, providing increase in intervals between maintenance operations, provision of a possibility of increase in a speed of circulation of a liquid flow and, respectively, increase in the total flow rate of the liquid flow at an input of a clarifier.
