The aim of this work is to study the process of water purification from mechanical and chemical pollution and pathogenic microflora by adsorption and ultrasonic methods. Proposed technology reduces bacterial contamination and purifies water from organic pollutants, improving its quality.

Devoted to the problem of sewage treatment by ultraviolet radiation. This method can clear the water from microbiological contamination and thereby improve water quality.

This article describes the life and scientific priorities of professor M. Malovanyy. It also provides details and results of a joint research with his students of a liquid media treatment from different types of pollution. The main research and its results are illustrated, as well as environmental technologies that were developed by using the archived results.

Acid rain influence determination created on the basis of sulfuric, nitric acids and their mixture on the chemical properties of soil substrates of different mechanical composition.

The prospects of the pharmaceutical industry development are closely connected with scientific and technological progress. In Ukraine, handling hazardous medical waste is an open question. The rapid development of pharmacy in recent years has created and increased the possibility of the generation and accumulation of pharmaceutical waste at the enterprises and in the environment. Only a few enterprises deal with medical waste disposal. Medical waste recycling requires an extremely high level of attention and carries great risks associated with handling this medical waste. When medical waste is burnt, strong pollutants are released into the atmosphere - carcinogens, furans and dioxins from chlorine halogen compounds, namely dumping of the hazardous material that contains heavy metals, and is likely to cause bioaccumulative hazardous substances to transfer to the environment.

In 2021, the situation with the collecting, processing and disposal of waste in general, solid waste in particular, remains difficult in Ukraine and needs to be solved immediately. Soil contamination, as well as contamination of surface and ground waters by filtration effluents (or filtrates), is one of the most dangerous consequences of non-regulatory disposal of solid household waste.
