Special Issue Information

Dear Colleagues,

Membrane technology has become an essential solution for water treatment and reuse, addressing the growing challenges of water scarcity and contamination. The commonly used membrane processes, including microfiltration, ultrafiltration, nanofiltration, reverse osmosis, and membrane distillation, effectively remove contaminants from water, leading to significant improvements in water quality for further reclamations. In recent years, continuous innovations in membrane materials and module designs have further enhanced the performance, efficiency, and cost-effectiveness of membrane-based water treatment and reuse systems.

In order to trace the research advances, we are pleased to invite researchers working in this field to share their studies on the application of membrane technology for water treatment and reuse. This Special Issue focuses on papers or review papers relating to membrane technology for water treatment and reuse, including, but not limited to, the following:

  • RO/FO/NF/ED/UF/MF process for water treatment or reuse;
  • Membrane distillation process for hypersaline water treatment;
  • Electro-driven membrane technology;
  • Controlling of membrane fouling or membrane wetting and the related mechanisms;
  • Advanced materials for membrane fabrication;
  • Removal of pollutants in wastewater;
  • Novel hybrid membrane systems;
  • Machine learning models for predicting membrane performance, fouling, etc.

Oxygenates removal from wastewater is an actual task for gas- and petrochemical industry. Pervaporation is one of most promising processes for oxygenates recuperation. In this work, pervaporation composite membranes with a polyalkylmethylsiloxane (alkyl substituents: hexyl, heptyl, octyl and decyl) selective layer were developed and studied for the first time during separation of the four-component mixture (1-butanol—1-propanol—ethanol—water). It was shown that an increase in the length of the side substituent of the selective layer leads to an increase in selectivity and a decrease in the permeability of oxygenates and water. The influence of the pore size of the support on the transport and separation properties of the membranes was studied. It was found that an increase in the pore size of the support leads to a decrease in the mass transfer resistance of the composite membrane. For example, for composite membranes based on polyheptylmethylsiloxane, normalized permeability was 33 × 10−3 and 11 × 10−3 molꞏmꞏPa−1ꞏm−2ꞏh−1 for membranes on micro- and ultrafiltration porous supports. The best separation characteristics in comparison with commercial membranes with a selective layer based on silicone rubbers were demonstrated by the polydecylmethylsiloxane and polyheptylmethylsiloxane composite membranes on microfiltration support: selectivities for n-butanol, n-propanol and ethanol were 2.0 and 2.3, 1.8 and 1.8, 1.0 and 0.9, respectively. Normalized permeabilities for n-butanol, n-propanol and ethanol were 33 × 10−3 and 16 × 10−3 molꞏmꞏPa−1ꞏm−2ꞏh−1, 30 × 10−3 and 12 × 10−3 molꞏmꞏPa−1ꞏm−2ꞏh−1, 16 and 6 molꞏmꞏPa−1ꞏm−2ꞏh−1, respectively.
