“…As a result of not replacing the filters of some small enterprises, it was observed that the waste water was discharged into canals or ditches without being completely cleaned. [2,8,17,18,19,20] By using local raw materials instead of imported filters, complete wastewater treatment is the solution to such problems, and economic efficiency is achieved. Local rounded quartz, activated carbon, activated bentonite, gravel (fine-grained) and gravel (largegrained) can be used as filter products.…”

Currently, in a situation where there is a shortage of fresh water around the world, there are increasing problems waiting to be solved, such as protection of water resources, effective use, and prevention of changes in their physical and chemical conditions. As one of the solutions to these problems, it is considered to make the treatment of waste water suitable for reuse or to achieve it by carrying out theoretical and practical research aimed at discharging ecologically clean water into nature. The article develops recommendations for water treatment and reuse using local raw materials for filter devices widely used in wastewater treatment by small enterprises. Experimental tests and hydraulic calculations were carried out for the use of local gravel, quartz sand, activated bentonite and coal, as well as industrial waste rubber granules as filter load. Taking into account the substances contained in their wastewater, the cleaning parameters were determined and recommendations were developed for the conditions of use. It was proved that the cleaning efficiency of activated charcoal or bentonite filters can be reached up to 90-96% for enterprises with high content of oil-oil products and surfactants. Using quartz sand, gravel, and rubber granules to clean wastewater from suspended matter has been proven to be 92-98% effective in experiments.

“…As it can be seen from the obtained results, based on the proposed compositions, it was proved that it is possible obtain rubber-textile, rubber-metal products, which are used in complex conditions in machine building, and their operational properties meet the required standards. The obtained results were based on the production conditions of the results obtained in the third chapter of the dissertation on the effect of 12% oligomer in VSPA on the properties of elastomeric compositions [16,18] .…”

In the article, the measures aimed at preventing vibrations generated in the wheel motor unit, one of the main most responsible units of mainline locomotives, are mentioned. There are different types of gears in the wheel motor unit, and the additional vibration is higher in the gear wheels of the assembled form. Because the gears of this assembly form are made of resinotechnical materials. This suspension element is made of V14 rubber technical material. The original purpose of the article is to use synthetic nitrite rubber SKN-18M instead of V14 rubber technical material based on local standards. It was studied that by changing the ingredients in SKN-18M and the sequence of their addition, it is possible to obtain a detail with improved vibration resistance and load bearing capacity. It was found that the amount of carbon-rubber gel and the vulcanization network of the material increased, the vulcanizate swelling level decreased, which is mainly due to the presence of oligomeric components on the surface of carbon particles. It is shown that the inclusion of this raw material in elastomeric compositions based on butadiene nitrile rubber increases the interaction at the “rubber-filler” boundary and the formation of additional bonds between rubber macromolecules and functional groups of the oligomer, and as a result, the overall technological and technical properties of the compositions are improved.
