KOCHETOV FLOTATION AND FILTRATION PLANT Russian patent published in 2017 - IPC C02F1/24 

FIELD: chemistry.

SUBSTANCE: protective mesh is installed at the ejector inlet to prevent clogging of the ejector nozzle, and the ejector has two fittings, one used to inject the reagent solution and connects to the metering pump via a tube, and the other serves for air suction, wherein both fittings have embedded check valves. The ejector is connected to a two-stage saturator, the second stage of which includes a pressure gauge and an output line connected to a single pipe, the second step of the saturator is connected to the distribution manifold via a check valve through nozzles located at the bottom of the flotation chamber containing a scraper, a tray and an overflow pipe associated with the upper part of the filter having an absorbing filtering media layer which is retained by supporting and clamping frames. Each nozzle manifold consists of a body with the nozzle rigidly connected to a housing coaxially disposed in the upper portion of the housing and having a cylindrical bore for fluid supply coupled to the diffuser which is axially symmetric to the housing and the fitting, and a sprayer located perpendicular to the housing axis and formed as a solid disc is connected to the lower part of the housing by means of at least three spokes. The adsorbent is shaped as perforated cylindrical rings, with a rigidly attached perforated circular base on one side, and a perforated round cover on the other, and the perforated cylindrical rings cavity is filled by ball elements made of active carbons, for example, "БАУ", "АР-А", "СКТ-3".

EFFECT: higher efficiency of waste water treatment.
