    Stabilization of active sludge after wastewater treatment contaminated by petroleum products
    (2016) Semenova, Olena; Reshetnyak, Lyudmila; Bublienko, Natalia; Smirnova, Elizabeth; Shylofost, Tatiana
    Biochemical purification of wastewater containing refined petroleum products takes place due to the oxidation of pollutants by active sludge organisms. As a result of this process the intense consumption of pollutants by active sludge and its growth occurs. Therefore, the possibility to use active sludge containing refined petroleum products after wastewater treatment requires its stabilization. Methods:I n this work the oxidation by a 30% hydrogenperoxide solution was studied for its use as a stabilizer. Chemical oxidizers, including hydrogen peroxide destroy organic polymers retaining free water thus promoting water release from the structure of sludge particles. On the other hand remains of fine structured oxidized biopolymers can lead to filter clogging, that is, reduce moisture exchange of sludge. Results: The experiment was carried out to find out the correlation between the doses of hydrogen peroxide andthe resistivity value of sludge filtration. Discussion: Stabilized active sludge can be used as a fuel for boiler rooms, which in its turn will reduce natural gas consumption for the enterprise needs.

    Improved flow sheet of dairies wastewater treatment at milk processing factories
    (2014) Semenova, Olena; Bublienko, Natalia; Smirnova, Elizabeth; Dyka, Oksana
    У статті обґрунтовано доцільність використання удосконаленої технологічної схеми очищення стічних вод молокозаводів. Доведено, що включення у схему флотатора сприяє видаленню нерозчинених органічних речовин, кількість яких у стічних водах зросла у зв'язку із збільшенням випуску кисломолочної продукції на молокозаводах, а використання зануреного дискового біофільтра як основної споруди біологічного очищення сприяє інтенсивнішій деструкції органічних забруднень тому, що він має ознаки традиційного біофільтра й аеротенка. In the article the feasibility of using advanced technological scheme of sewage treatment, milk. It is proved that the inclusion in the scheme helps to remove undissolved Flotators organic matter guestrooms at wastewater increased due to the increased release of dairy products in dairies, and the use of submerged biofilter disk as the basic structure of biological treatment promotes more intensive degradation of organic contaminants that he has elements of traditional biofilter and aeration tanks.

    Use of higher concentration of active sludge organisms for intensifying dairies’ wastewater treatment process
    (2013) Bublienko, Natalia; Semenova, Olena; Smirnova, Elizabeth; Suleyko, Tetiana; Reshetnyak, Lyudmila
    Проаналізована екологічний стан підприємств харчової промисловості, зокрема молокопереробної галузі. Підтверджено ефективність застосування комплексної анаеробно-аеробної технології. Запропоновано спосіб інтенсифікації стадії аеробної ферментації застосуванням підвищеної концентрації активного мулу. Це дасть змогу значно прискорити процес очищення і зменшити тривалість процесу. Analyzed the ecological state of the food industry, particularly the dairy industry. Confirmed the effectiveness of the integrated anaerobic - aerobic technology. The method of intensification stage aerobic fermentation using a high concentration of activated sludge. This will significantly speed up the cleaning process and reduce the duration of the process.

    Purification of oil wastewater
    (2012) Semenova, Olena; Bublienko, Natalia; Smirnova, Elizabeth; Shylofost, Tatiana
    The given article discusses the problem of treatment of oil wastewater. It is known that the problem of oil wastewater treatment is topical nowadays, because as a result of various technical and technological processes the formed oil wastewater is not utilized properly. The article provides the information of pollution of oil waste¬water which is produced by the food enterprise, and also the ways of its purification. The objective of research is the intensification of the process of biochemical treat¬ment. Scientific novelty of the research lies in biosorbtion of oil gas-liquid counter-current mode and oxidation in an airtank-clarifier.
