The article discusses the study of swirling flow in technological pipelines. It examines the nature of the swirling flow, presenting the experimental velocity distribution and pressure inside the pipe in graphical and tabular form. The scope of the study includes the displacement of liquid and gas, as well as the purification of natural waters using ozone and chlorine. The article analyzes the existing technological processes for the preparation of drinking water from surface water sources in Uzbekistan. Due to the significant volumes of water consumption for economic activities, the issue of drinking water disinfection is crucial. In addition to traditional disinfection methods, modern researchers are focusing on developing innovative technologies for this process. The article also studies the features of water formation and its qualitative composition, with an analysis of the reliability of the existing drinking water treatment technology.

This article deals with the issues of determining the mineralogical composition of soil samples in the city of Navoi and the Karmaninsky district (the settlement of Khazora, 24 km from the city) and identifying the degree of salinization of these old irrigated soils in the region. To determine the mineralogical composition of soil soils, the X-ray diffraction method of research was used, and to determine the functional groups of carbon, sulfur, and chlorine, IR spectrometric analysis of samples was used. The studies carried out made it possible to establish a carbonate type of salinity for the city of Navoi, and for the Karmaninsky district, the dominance was noted first of carbonate - 45.4%, then sulfate 28.8%, and only lastly did the third type of salinity appear, represented by chloride - 0.8%, found on the surface layer of the soil (0-0, mm).

In this article, scientific research on the production of thermophosphate fertilizers was carried out on the basis of thermo-alkaline activation of Central Kyzylkum waste phosphorite with mineralized mass and alkali metal salts, namely NaCl, KCl, Na2SO4, K2SO4, Na2CO3, K2CO3 and silica at high temperature. In this case, samples are heated in muffle furnaces at temperatures of 800°C, 900°C, 1100°C, 1200°C and for 30 min, 60 min, 120 min. The total P2O5, assimilable P2O5, total СaO and total СO2 forms of the sintered tablets were investigated. As it can be seen from the experiments conducted with mineralized mass phosphorite, alkaline salts and quartz sand, it was found that the assimilated form of СaO, P2O5 and the degree of decarbonation rose with increasing temperature and time.
