Abstract:
For municipal water supply systems, industrial enterprises, and thermal plants, the content of mineral impurities in water is regulated, which necessitates the use of technologies for their removal. The object of study was water from an artesian well, which was treated on a rotor-pulsation apparatus that implements the principle of discrete-pulse energy input in an aeration-oxidizing setup of rotor type. The effect of the principle of discrete-pulse energy input on the process of extracting calcium bicarbonate from water to reduce its hardness is studied. It was determined that when treating w

Abstract:
Thousands of steam and water boilers of medium and low parameters operate in the country's industry, municipal energy, and agriculture. Their reliable work is largely determined by maintaining a rational water-chemical regime. Dissolved impurities that affect the operation of boiler equipment primarily include hardness salts. When using hard water, scale is formed on the surfaces, heat transfer deteriorates, and pipes are overheated from the heating side, which can lead to their destruction.
 The purpose of the work is to improve the quality of softened water, reduce the consumption of re

Abstract:
Existing feed devices use methods of grinding grain and other components of the feed mixture in hammer crushers, which requires significant costs of mechanical (electrical) energy. Therefore, it is necessary to develop devices with a high degree of impact on the treated environment, which increases productivity and reduces energy consumption in technological processes. Such devices include rotor-pulsation devices, the principle of operation of which is based on the method of discrete-pulse energy input. The basis of this method is a multifactorial effect on the treated liquid homogeneous or he

Abstract:
The article provides an overview of the design features of rotor-pulsation devices in which the method of discrete-pulse energy input is implemented – a method of intensification of heat and mass exchange processes, which contributes to the development and implementation of energy-saving technologies in various industries. The idea of DPEI is to accumulate the energy previously distributed in the working volume in a stationary and arbitrary state in local discrete points of the system and then implement it in pulses to achieve the necessary thermophysical effects.

Abstract:
This article presents the results of experimental processing of hydrocarbons (petroleum and mixtures based on them) on a laboratory stand. Cavitation treatment was carried out in flow-type rotary-pulsation apparatus with different impeller diameters and rotor rotation frequencies. The aim of the work was to determine the most effective processing mode for oil blends and distillates within the framework of laboratory experiments.

Abstract:
Voltage unbalance is one of the power quality problems causing a lot of ill effects on induction motors. These are namely: Overheating, line-current unbalance, derating, torque pulsation, and inefficiency. The objective of the present work is to assess and quantify the effects of voltage unbalance on induction motors using both theory and experimentation. The analytical study is performed using the complex voltage unbalance factor model of this problem. The work deals specifically with the influence of the variations in the complex angle of the voltage unbalance factor on the stator and rotor
