“…However, when small facilities are restructured, their existing arrangement and layout should remain unchanged, and this idea is particularly relevant in case of limited areas occupied by water treatment facilities [3,17]. Therefore, there is a need to study the installation of membranes in close proximity to existing structures; they can function in small containers to avoid the construction of new tanks [1,5,7].…”

“…Однако при реконструкции небольших объектов наиболее целесообразно не нарушать существующую схему и расположение сооружений на площадке, а также их конструкцию, что особо актуально в условиях ограниченных площадей [3,17]. Таким образом, требуется более детальное изучение вопроса применения решений по модернизации станций с помощью дополнительного мембранного оборудования, которое возможно разместить в непосредственной близости с существующими сооружениями в небольших контейнерах без устройства новых капитальных емкостей [1,5,7].…”

“…Современные тенденции развития и совершенствования процессов биологической очистки заключаются в улучшении качества удаления биогенных элементов [1]. Это достигается благодаря увеличению времени обработки (в зарубежной литературе используется термин hydraulic retention time) и доз ила, что ведет к увеличению объема сооружений.…”

“…Current trends in development and improvement of biological treatment processes focus on enhancing the removal of biogenic elements [1]. It's attainable by increasing the treatment time (the term "hydraulic retention time" is in use in the international literature) and the content of mixed liquor suspended solids (MLSS) which cause the size of wastewater treatment facilities to go up.…”

Introduction. 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. Materials and methods. 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. Results. 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. Conclusions. 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.

Fouling is one of the most challenging issues faced by membrane technology. One possible approach to address membrane fouling is incorporating hydrophilic materials into the membrane matrix. Graphene oxide (GO) can be a potential candidate due to its hydrophilicity, if its cost could be significantly reduced. In this study, a GO‐polysulfone (PSF) composite membrane is fabricated with a thin GO‐PSF active layer and a PSF substrate. The obtained membrane shows good anti‐fouling property in real sewage system, compared with the pristine PSF membrane, and the flux recovery ratio is enhanced by 20%–30%. In addition, the antibacterial property of GO‐PSF membrane to Escherichia coli is enhanced. The work provides a guidance to improve the performance membranes and reduce the cost.
