В качестве исследуемой жидкости использована синтетическая сточная вода, которая по своему составу соответствовала городским сточным водам, с различными концентрациями взвешенных веществ (доза ила). В экспериментах использован мембранный элемент производства компании Raifil (Корея) с капиллярными ультрафильтрационными мембранами. Размер пор мембран - 0,1 мкм. Общая площадь фильтрующей поверхности мембран - 1 м2. Данный мембранный модуль обладает стандартными характеристика (размер пор, материал) для ультрафильтрационных мембран, поэтому можно предположить, что полученные в дальнейшем результаты не будут иметь существенных отличий в случае использования ультрафильтрационных мембранных модулей других производителей.</p></sec><sec><title>Результаты</title><p>Результаты. </p><p>Описана разработанная методика оптимизации величин рабочего давления и доз ила, при которых ведется процесс мембранной очистки. Получены значения операционного давления, при котором резко возрастает количество взвешенных веществ в фильтрате, т.е. начинается проскок взвешенных веществ в фильтрате или проскок загрязнений. Определены параметры работы установки, при которых возможно добиться наибольшей производительности.</p></sec><sec><title>Выводы</title><p>Выводы. </p><p>Полученные результаты позволяют наметить дальнейшие направления исследования по оптимизации работы мембранных биореакторов (как отдельно стоящих, так и погружных) для нужд очистки сточных вод.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. </p><p>The study focuses on the operation of a standalone membrane bioreactor applicable as an alternative to submerged membrane modules widely used as part of small capacity wastewater treatment facilities.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. </p><p>An ultra-filtration membrane was used to perform the research in a laboratory environment. The liquid, exposed to research, represented synthetic wastewater, whose composition was similar to the one of urban wastewaters, and it had varied concentrations of suspended solids (MLSS). The membrane element, produced by Raifil (Republic of Korea), that has capillary ultra-filtration membranes, was used in the experiments. The membrane pore size is 1 micron. The total membrane filter area is one square meter. This membrane module has standard characteristics (pore size, material), typical for ultra-filtration membranes; therefore, we can assume that any further results will not demonstrate any substantial discrepancies, if ultra-filtration membranes made by other manufacturers are used to conduct experiments.</p></sec><sec><title>Results</title><p>Results. </p><p>The author describes a methodology for the optimization of pressure and MLSS values used in the process of membrane treatment. The author obtained the pressure values at which the amount of suspended solids in the filtered material shows a sharp rise, which means a slip of suspended solids into the filtrate, or a slip of contaminants. The author also identified the operating parameters that ensure maximal capacity.</p></sec><sec><title>Conclusions</title><p>Conclusions. </p><p>These findings help to outline a roadmap for further research into the optimization of membrane bioreactors (both standalone and submerged units) used in wastewater treatment.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>рочистка сточных вод</kwd><kwd>мембранные биореакторы</kwd><kwd>доза ила</kwd><kwd>фильтроцикл</kwd><kwd>wastewater treatment</kwd><kwd>MBR</kwd><kwd>mixed liquor suspended solids</kwd><kwd>filter cycle</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Sathya U., Nithya K.M., Balasubramanian N.
