This paper reports a study into the dependence of efficient glycerate potassium production involving glycerin and potassium hydroxide solution on the process conditions. The concentration of potassium glycerate in the resulting product has been used as a parameter of the efficient glycerate potassium production process. Glycerates of metals are applied to produce articles in the construction industry, electronics, medicine; they are employed as transesterification catalysts to obtain special fats for various purposes, as well as biodiesel fuel. In order to derive potassium glycerate, heating was applied while agitating a mixture of glycerin and potassium hydroxide. The analysis of potassium hydroxide was performed, in which the basic substance mass fraction was 85.5 %, the mass fraction of carbonate potassium – 0.9 %. The p.a.-grade glycerin was applied in this work, whose basic substance mass fraction was 99.5 %. The effect of the heating temperature of the reaction mixture on the concentration of potassium glycerate in the product has been determined. It has been shown that the rational heating temperature is 145 °C. The dependence of potassium glycerate concentration in the resulting product on the following conditions of the process has been established: a change in the molar concentration of glycerin and a reaction mixture heating duration. Such rational conditions for obtaining potassium glycerate have been defined as a molar concentration of glycerin of 60 % and a heating duration of 4 hours. The experimentally established concentration of potassium glycerate in the product under these conditions was 75.77 %. For potassium glycerate, the melting point (69 °C) and the mass fraction of moisture (0.8 %) have been determined. The results of experimental studies would make it possible to obtain potassium glycerate directly at enterprises where the glycerates of metals are used, from available raw materials, under rational conditions. The defined conditions for obtaining potassium glycerate could make it possible to efficiently utilize material and energy resources.

The reuse of treated domestic wastewater is an imperative source of water for numerous purposes. The treatment of municipal wastewater can be process by utilizing the technique for electrocoagulation. Electrocoagulation (EC) is an eco-friendly technique that combines the functions and advantages of conventional coagulation, flotation, and electrochemistry in water and wastewater treatment. The aim of present study was to assess the potential of electrocoagulation process in removing COD, BOD, TSS, turbidity, sulphate, nitrate, chloride and TDS from municipal wastewater. This experimental study was carried out at a batch system by using copper and aluminium electrodes aiming to treat the municipal wastewater at (0, 7, 14, and 21 volts, 50mamp for 60minutes) from Sample Baloch Colony (SBC), Sample Rind Goth (SRG), Sample Cattle Colony (SCC), Sample Pakistan Machine Tool Factory (SPMTF) and Sample Mehran Highway (SMH). The results revealed that the maximum removal efficiency of COD 96% for SPMTF, BOD 38.5% for SPMTF, TSS 98.14% for SMH, Turbidity 95.7% for SPMTF, Sulphate 95.9% for SRG, Nitrate 95.23% for SMH, Chloride 97.92% for SMH and TDS 96.9% for SRG at 21 volt. The present study suggested that the treated wastewater could be safely reuse for lawns, parks, tree plantation and recreation purpose.

Abstract. In today's conditions, there is a need to find new and effective ways (means) to protect armored vehicles and increase their protection against modern means of destruction, as evidenced by the analysis of the damage received by armored vehicles during the repulsion of armed aggression against Ukraine. Various methods and means of additional protection always require practical verification of their feasibility. The purpose of this article is to present the main approaches to assessing the level of stability of an armored obstacle with additional armor and to build a mathematical model of the impact of 12.7 mm kinetic munitions on an armored obstacle with additional armor based on experimental data. To assess the relative properties of the armor barrier to the destructive energy of the munitions, the experimental-statistical method of mathematical modeling of the process of influence of the energy of the munitions on the armor barrier of armored vehicles was used, in which the experiment is considered as the main source of information about the process, and the methods of probability theory and mathematical statistics are the main means of processing the results of the experiment. The experimental study allowed to check the resistance of the armored barrier with additional armor to ammunition of 12.7 mm caliber, which destroys it under the action of kinetic energy. As a result of a multifactorial experiment, experimental data were obtained. Using the experimental data, a mathematical model of the impact of 12.7 mm kinetic ammunition on an armored obstacle with additional armor was built, which takes into account the angle of the meeting of the munition with the armored obstacle, the distance from the armored obstacle to the additional armor, the thickness of the additional armor. This mathematical model can be used to find the optimal additional armor of armored vehicles, taking into account the angle of inclination, the distance of additional armor to the main armor and the thickness of additional armor.
