Item Technology for Water Purification From Residues of Drugs and Plastic(Дніпровський національний університет залізничного транспорту імені академіка В. Лазаряна, Дніпро, 2019) Dolina, Leonid F.; Mashykhina, Polina B.; Dolina, D. A.EN: Purpose. The main purpose of the article is to develop a technology for water purification from residues of oilfat-cream containing drugs, in particular technology and a technological scheme for purifying urban (municipal) wastewater from plastics and residues of drugs. Methodology. The studies were carried out based on the analysis of scientific sources and reporting data on the availability of drugs and plastics in the water of Ukraine, European countries, and the USA. Findings. The authors present the results of a comprehensive review of issues related to the determination of the availability of drugs in various waters, their concentrations and the most dangerous drugs-toxicants. Medicines and plastics can accumulate not only in humans and animals, but also in sea and river fish, etc. The presence of drugs and plastic in the body can have a negative impact on the health. The treatment facilities in Ukraine and the world are not sufficiently adapted for the detection of drugs and plastics and their purification. Originality. The authors of this material conducted studies to determine the content of plastic in drinking tap water in Dnipro and Zaporizhzhia cities. Drinking water from the tap contains less plastic particles than bottled water of the famous Ukrainian trade brands. The work developed technological schemes for the purification of industrial wastewater from pharmaceutical enterprises for the manufacture of creams, ointments, oils and other products for treatment and cosmetic purposes. Structures and methods for purifying water from these pollutants have been pro-posed, which had not been previously used at water purification stations, but successfully apply in other industries. Practical value. The use of environmentally efficient technologies in Ukraine will allow obtaining high-quality drinking water, but it will require re-equipment and reconstruction of water treatment plants. Major funding should be provided by corresponding articles. Currently, in Ukraine (even in Kyiv) there are no stations for the purification of drinking and waste waters, which would use modern technologies and facilities, but high-quality water is the health and life of people.Item Water Reality in Ukraine and Worldwide(Дніпропетровський національний університет залізничного транспорту імені академіка В. Лазаряна, Дніпро, 2017) Dolina, Leonid F.; Mashykhina, Polina B.; Karpo, Alina A.; Mishchenko, Andrey A.EN: Purpose. The paper analyzes the state of water management in Ukraine and worldwide, as well as the best practices in this area. Methodology. The study was carried out based on the analysis of literature sources and reporting data on the state of water management in Ukraine, European countries, the USA (2010-2016). Findings. The water state analysis in the regions of Ukraine showed that the quality in most cases is close to or meets the requirements for drinking water. Drinking tap water requires post-treatment in all regions of the country. The main issue for today is the production of the necessary equipment for treatment plants. Unfortunately, not all equipment is produced in Ukraine. The condition of rural water pipelines is of particular concern. Among the tested pipelines 7.3% do not comply with the rules and regulations. At the same time, only 25% of villages in Ukraine are provided with centralized water supply. Originality.The authors presented the results of a comprehensive review of the world's issues on disinfection of drinking and waste water, where various methods are used, partly in combination with each other in Ukraine and the worldwide. The main unresolved issue today is the issue of the residual quantity of drugs in the drinking water. The main environmental threat of the world scale is the presence of medicines in drinking water. The treatment facilities are not suitable for the decomposition or trapping of medicinal products. Nowhere in the world there is protection from these substances. One of the key issues in the solution of drinking water production is seawater desalination. To reduce the cost of desalination of sea water the SWRO-membrane technology is used. Practical value. Water problems are number one problems all over the world and in Ukraine as well. It is necessary to provide for additional financing to solve problems in the preparation and purification of waters, not with whatever funds remain, taking into account the fact that water is the basis of life on earth as a whole, the health and life of the nation depends on the quality of the water supply source.
