Special Issue Information

Dear Colleagues,

Membrane processes are the most widely applied and versatile technologies available for quick and easy separation of the mixture constituents. Although membrane technologies are remarkably effective, the complexity of the processes in which they are employed makes it necessary to improve them continuously. One of the most renowned and challenging applications of membrane processes is wastewater treatment. The complexity of urban wastewater, which includes solid and liquid contaminants of various characters and properties, favors the use of membrane technology as the most efficient method of treating large volumes of wastewater quickly and effectively. However, selectivity and membrane fouling are constantly a great concern, along with the selectivity of the membranes and the application of membrane processes in valuable compound recovery from wastewater.

Therefore, the aim of this Special Issue is to present novel approaches to membrane technologies applied in urban wastewater treatment, as well as the utilization of urban wastewater membrane technologies for valuable substance recovery from wastewater and the implementation of various membrane types and reactors for efficient separation of multiple compounds to support the sustainability of urban society.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

  • Advanced membrane technologies for wastewater treatment.
  • Membrane bioreactors.
  • Wastewater emerging contaminants separation.
  • Membrane separation and recovery of valuable compounds.
  • Advances in membrane materials.
  • Membrane-based processes in wastewater.
  • Advances in membrane technologies and membrane fouling.
  • Selective membranes in urban wastewater treatment.
  • Sustainable membrane technologies.

We look forward to receiving your contributions.

This analytical study was conducted on the basis of statistical data from the Russian Federation and technological requirements for WWTP operation. As a case study, a virtual WWTP, which serves a residential area of 31,500 PE (personal equivalent), was considered to solve a task of their potential upgrade. According to the initial data, within modernization, the existing infrastructure of the WWTP should be considered in order to receive wastewater with a reduced flow rate and increased values of pollutant concentrations. Within the analysis, treatment efficiency should correspond to current regulations. Special focus was put on secondary treatment facilities, as they ensure the removal of major contaminants (organic pollution) and nutrients (nitrogen and phosphorus). The results showed that even in the case of a lower flow rate, higher pollutant concentrations demanded a doubled volume of activated sludge reactor to provide the required efficiency. An increase in oxidizing capacity may be ensured through the growth of mixed liquor suspended solids (MLSS) value with simultaneous transition from gravity to membrane sludge separation. A study revealed that an MLSS raised from 3 to 8 g/L allows treatment in the existing tanks to be performed with necessary efficiency. In this case, significant costs for the purchase of membranes are offset by the need for zero additional construction. On the other hand, such a transition leads to an increase in operating costs of 60% (from EUR 0.078 to EUR 0.12/(m3/d)). Full article
