HANDLING THE PHARMACEUTICAL INDUSTRY WASTE IN UKRAINE AND THE UA

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 recyclingrequires an extremely high level of attention and carriesgreat risks associated with handling this medical waste.

APPLICATION OF POLYMERIC DISPERSION FOR CLEANING SURFACE OF ARCHITECTURE MONUMENTS

The use of aqueous polymer dispersions of butyl acrylate-methyl-acrylate-methacrylic acid and polyvinyl acetate for purifying the surface of tiles of the 18th and 19th centuries, fragments of carved stone blocks of window frames XVII, bricks of the sixteenth and nineteenth centuries, and plaster brackets of the late nineteenth century, tiled tiles from the facade of the building of the city of Lviv, the areas of the surface of the Boim's chapel in Lviv, metal plates of models of coriand and stucco decor from the main building of the National University of Lviv Polytechnic.

Kinetic Modeling Studies of Enzymatic Purification of Glucomannan

Purification of glucomannan by hydrolising starch – the main contaminant – was studied. Hydrolysis removed 88.7 % of starch. The highest glucomannan сontent was found to be 73.35 %. The sample showed the comparable infrared spectra to those of the commercial glucomannan. The kinetics of enzymatic hydrolysis was evaluated using the Michaelis-Menten model.

INVESTIGATION OF CAVITATIONAL EXPANSION OF SODIUM HYPOCHLORITE UNDER ISOTHERMAL CONDITIONS

Liquid waste and wastewater, that contain hypochlorites, are formed during the production of chlorine and caustic soda; electrolytic production of magnesium and chlorine; in the production of pulp and paper products etc. Such wastewaters belongs to sub-standard, therefore they are not reused in corresponding technological processes. In accordance with the current normative documents, hypochlorite wastewaters must be disposed of at the local treatment facilities of the enterprises where they are produced.

The Decision of Landfill Leachate Treatment

This work is an attempt to analyze the theoretical and practical aspects of landfill leachate treatment and analyze the pros and cons of the most widespread methods leachate treatment and suggest the method of complex purification of high-concentration sewage waters from solid domestic wastes (SDW) for example of Hrybovychi municipal solid domestic waste.

Проблема очищення фільтрату полігонів твердих побутових відходів та шляхи її вирішення

Досліджено основні проблеми, що виникають у сфері поводження з фільтратом
полігонів твердих побутових відходів. На основі даних про хімічний склад фільтрату
обґрунтовано необхідність встановлення локальних систем очищення фільтрату на
території полігону перед скиданням його в каналізаційну мережу та розроблено
принципову схему очищення фільтрату на прикладі Львівського полігону. Запропо-
новано ряд заходів щодо оптимізації поводження з твердими побутовими відходами, які
