Item Experimental research of parameters of industrial waters of canning plant and bakery. Analysis of treatment technologies(Видавництво Львівської політехніки, 2021-06-01) Havryshko, Marianna; Popovych, Olena; Yaremko, Halyna; Lviv Polytechnic National UniversityOne of the industries that uses large amounts of water is the food industry. Industrial, domestic managers of the production process stand out with it and enter the environment surrounded by contaminated effluents. Their main feature is the high content of dissolved organic matter and nitrogen. You can also create wall water to create aggregate-resistant colloids, which include animal and vegetable fats, proteins, starch, sugar, as well as salts, carbohydrates, dyes, thickeners, preservatives. As a result of the technology of treatment of such industrial effluents, is a combination of different technologies and methods of treatment and the creation of several units depending on the parameters of wastewater. The purpose of our work is: 1) Analysis of physical and chemical indicators of industrial waters of food industry enterprises, monitoring of their impact on the environment; 2) to outline perspective directions of technologies of industrial water purification and creation of closed water circulation systems.Item Ecological aspects of alcohol industry enterprises modernization at present stage of development(Видавництво Львівської політехніки, 2020-02-24) Havryshko, Marianna; Popovych, Olena; Yaremko, Halyna; Lviv Polytechnic National UniversityAt the present stage of development, the entire world industry has faced the problem of rational use of renewable natural resources, in particular the most efficient ways of wastewater treatment and the use of accumulated waste in the production process as secondary raw material. In particular, the alcohol industry, as one of the components of food, medical, chemical and various industries, leads to the formation of a huge amount of waste, including wastewater. The food industry, like any other industry, has a negative impact on the environment. Water bodies are the most affected by the food industry. Almost the first place in terms of water consumption per unit of production is the production of alcohol. Consumption of large amounts of water leads to the formation of wastewater, which is highly polluted and adversely affects the environment. Due to the high chemical and biological consumption of oxygen, specific colour and odor, suspended solids, low pH value, the purification of such waste in the filtration fields, and discharge into water bodies is not possible. The purpose of our work is: 1) the analysis of the alcohol industry potential in Ukraine in recent years, and methods of waste disposal as a potential source for the development of bioenergy. 2) environmental aspects of the alcohol industry modernization at the present stage of development and implementation of modern wastewater treatment technologies.
