After that, the mass of the filtered residue of oil products obtained from each sample is measured. The dispersant efficiency of the is determined by the ratio of the weight of the filtered oil product to the total mass of oil products in the mixture placed in the test vessel, taking into account the natural dispersion determined at the zero stage of testing, where at the zero stage of testing, the natural dispersion of oil products in the thickness of the liquid sample to be examined is determined at least to the middle zone of test capacity and natural dispersion time.EFFECT: increased accuracy and speed of dispersants efficiency determination.2 dwg, 1 ex

The service surface spillway at the Zeya HPP is supplemented by at least one classical aqueduct. The aqueduct is functionally a continuation of the service surface spillway. The conjugation with the aqueduct is made above the springboard of the service surface spillway. The aqueduct, from conjunction with the tray of the service surface spillway before reaching the horizontal position of the aqueduct, has smooth curvature, allowing the watercourse to undergo without spray, i.e. smooth flow to the outlet, which is made at a considerable distance from the dam base.

The inclination angle of the visor 7 is adjusted by the telescopic support relative to the bottom of the supply channel 2. The water flowing through the channel 2 is divided into three flows by the bottom tray 3 with dividing walls 4. The visor 7 is arranged of such a length that the jets flowing from it flow directly into the expanding well 5, which has a rear wall with the reverse bias towards the longitudinal axis of the transit channel 1 and can ensure the energy dissipation in the well 5. Thereinafter, the total flow from the well is smoothly connected to the flow of the channel 1.EFFECT: increasing the reliability and efficiency of hydraulic conditions in the channels junction area, reducing the dynamic loads towards the longitudinal axis of the transit channel.2 dwg

ethod for cleaning livestock drainage and surface waters and device for its implementation // 2630791
FIELD: agriculture.SUBSTANCE: livestock drainage and surface waters from a drainage system 1 are collected and accumulated in a closed channel 5, they are pumped by a mobile pumping station 6 through a supply pressure pipe 7 to a storage pond 8. Then, water is released into a brook 11, limiting it so that the content of harmful substances in the water at the end of the brook 11 when entering a river does not exceed the maximum permissible norm. The closed channel 5 is communicated with the channel of the brook 11 by an additional discharge channel 13, which is located perpendicularly to the bed of the brook 11, is made sloping, is equipped with thickets of higher aquatic vegetation, and has a baffling adjustable structure 14. The channel 5 is made with the possibility to transport livestock drainage and surface waters with a variable flow through it. In the storage pond 8, a water intake device is installed, made in the form of a tank 15 with the perforated upper and lower wall, installed in the center of the platform 18, connected to a pressure water conduit with the possibility of forming a water inlet to the beginning of the discharge pipeline 9 and then to the brook 11.EFFECT: invention allows to increase the efficiency of draining excess drainage and surface runoff into a closed channel and to improve the operating conditions using a brook flowing from a natural water source.5 cl, 2 dwg

ethod for purifying stagnant reservoir under conditions of continuous ingress of oil products // 2629786
FIELD: oil and gas industry.SUBSTANCE: method is carried out using sorbent, coagulant and coarsely dispersed mineral substance. The water withdrawn from the reservoir is subsequently purified by filtration through a hydrocarbon fluid layer, sorption in a carbon-containing fibrous material, filtration in a geochemical barrier filled with mineral granular material, where electrochemical current sources generating the coagulant are disposed. Purified water is returned to the reservoir, where the mixing of purified and untreated water is limited. At the same time, interception of ground water-oil emulsions entering the reservoir and their purification by liquid filtration in hydrocarbon fluid layer with afterpurification together with water extracted from the reservoir are performed. The extracted bottom sediments are composted together with carriers of microorganisms, structurants and biogenic elements.EFFECT: improved efficiency of water and reservoir bottom sediments purification.1 dwg, 4 ex, 4 tbl
