The adsorption of Copper (II) and Chromium (III) from aqueous solution by natural zeolite was investigated in fixed bed column. The effects of selected operating parameters such as flow rate and bed depth were evaluated. The breakthrough data are fitted well to Bed Depth Service Time (BDST) and Thomas models with high correlation coefficient, R2 = 0,91. The results showed that zeolite can be an effective adsorbent for Copper (II) and Chromium (III) removal.

The adsorption method of after-treatment of wastewater from the production of vegetable oils was investigated. The reasons of choice the activated carbon as adsorbent was justified. The statics and the kinetics of the adsorption process by activated carbon the organic component from the wastewater of oil production after extraction cleaning was investigated. The experimental data based on the theory of Freundlich and Langmuir were processed and the main constants of the process were defined.

Показано, що одним із перспективних напрямів вирішення проблем екологічної безпеки довкілля є створення високоефективних методів знезараження стічних вод та руйнування наявних в них органічних сполук. Запропоновано конструкцію та описано принцип роботи створеного для очищення стічних вод пивоваріння електромагнітного вібраційного кавітатора, досліджено ефективну технологію віброкавітаційного очищення стоків харчових виробництв.

The aim of this work was to study the process of adsorption of Copper and Chromium cations by natural zeolites in static conditions. The change of the chemical composition of the surface of the zeolite as a result of sorption of heavy metals was investigated. The influence of the type of the ions and pH selectivity in absorption of heavy metals removal by zeolite was analysed. The reasons for the selective extraction of Copper from two-component solution were explained.

In the given article the theoretical bases of adsorption of typical contaminations of wastewaters are grounded. The review of literary data in relation to application of the klynoptylolite of Sokirnitsa deposit in engineering of environment is carried out. Experimental data of adsorption capacity of natural klynoptylolite are resulted. A mechanism and features of processes of adsorption in static terms is described. Conformities to the law of change of adsorption capacity in accordance to the parameters of molecules of adsorbate were observed.

The present article substantiates the theoretical bases lactic acid adsorption on mineral and carbon adsorbents. Monitoring of wastewater contaminated with wastes of dairy plants, estimation of quantities, peculiarities of wastes localization and estimation of toxicological impacts on the environment was carried out. The existing theoretical apparatus for adsorption processes description was analyzed. Adsorption process mechanism and methods for identification of experimental data in theoretical models was developed.

In this paper the efficiency of ANAMMOX-process use for sewage treatment from nitrogen-containing compounds was investigated. The conditions for promoting the efficient passage of the studied process and the methods of investigation of the anaerobic ammonium oxidation – ANAMMOX were presented. Досліджена ефективність застосування ANAMMOX-процесу для очищення стоків від азотовмісних сполук. Наведені умови, що сприяють ефективному проходженню досліджуваного процессу, та методи, за допомогою яких проводилось вивчення анаеробного  окиснення амонію – ANAMMOX .
