An innovative approach to wastewater treatment dairies
(2013) Semenova, Olena; Bublienko, Natalia; Reshetnyak, Lyudmila; Suleyko, Tetiana
The characteristics of dairy wastewater are given and characterized by the harm they cause to the environment. Aerobic biochemical purification is proposed. For stimulation of the process, intensive biochemical methods are used.
Biochemical purification of industrial oil wastewater
(2013) Semenova, Olena; Bublienko, Natalia; Shylofost, Tatiana; Reshetnyak, Lyudmila
The information on indicators of pollution of oil-containing sewage generated at an industrial enterprise is given. The existing methods of clearing such sewage are analyzed. The advantages of the technology of biosorption of petroleum products in the mode of gas-liquid counterproduction and oxidation to aerotanks are given.
Cleaning of sewageswith use of pinotenk
(2016) Semenova, Olena; Bublienko, Natalia; Shylofost, Tatiana; Semenova, Alexandra; Reshetnyak, Lyudmila
Characterized sewage containing hydrocarbons. It is shown that their purification is a complex biological process. This is due to the peculiarities of dissolving contaminated components in water. The use of the biosorption process for wastewater treatment with such contaminations is proposed. The principle of work of a pinotek, its advantages, features of use is given. The indicators of wastewater pollution before and after cleaning are shown.
Improved flowsheet of wastewater treatment from nitrogen a containing compounds
(2015) Semenova, Olena; Reshetnyak, Lyudmila; Bublienko, Natalia; Salavor, Oksana; Smirnova, Elizabeth
Waste water containing nitrogen compounds stimulate the growth of plankton, algae and violate the oxygen regime, affecting the livelihoods of aquatic organisms. Wastewater treatment of nitrogen carried activated sludge in suspended state or immobilized using active biomass.
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.
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.
Wastewater treatment from nitrogen compounds
(2020) Semenova, Olena; Bublienko, Natalia; Suleyko, Tetiana; Reshetnyak, Lyudmila
Increasing the concentration of nitrogen compounds in wastewater has led to a deterioration of surface water quality, which is the main source of economic drinking water supply for the vast majority of Ukrainians. The Government of reservoirs in the territory of Ukraine recorded an excess of norms for ammonia nitrogen – 2 – 15 times, nitrates – 7 – 20 times. The consequences of contamination with nitrogen compounds are eutrophication, which is caused by hypertrophied development of algae («flowering»); reducing oxygen content. We have proposed biological sewage treatment with this type of contamination.
