Membrane Technologies

Membrane based processes are the future of green industrial fluids separation with low operational cost and high-quality end products.

  • Generally, membrane-based processes are divided into two types, Pressure driven membrane sepration processes such conventional membrane filtration systems like Microfiltration (MF), Ultrafiltration (UF), Nanofiltration (NF) and Reverse Osmosis (RO) systems. While the other type is thermally driven membrane sepration processes such as membrane distillation (MD), pervaporation (PV) and vapour permeation (VP) solutions.
  • Thermally driven membrane-based solutions are great alternatives to conventional thermal distillation, as they can achieve higher sepration efficiency at lower temperatures while thermal distillation fails to achieve the desired sepration efficiency in many application due to azeotropes.
Membranes Distillation MD

Membranes Distillation (MD)

Membrane Distillation (MD) is considered as one of major emerging techniques for sepration of ono-volatile solutes from water. MC is a thermally driven membrane baseed sepration process, in which porous hydrophobic membrane is used for sepration. MD haas the ability to use low grade and inexpensive heat sources, smaller plant footprint, and lower capital costs than conventional distillation processes.

MD can be used for the production of distilled water and for concentrating aqueous solutions. De-salting sea water and the production of clean water from brackish water are the most common MD applications because non-volatile ionic particles are almost completely retained.

MD is used for the water purification in the pharmaceutical, chemical and textile industries, for the concentration of fruit juices and milk processing, in bio-medical applications like the removal of water from blood, in the concentration of cooling liquids (glycols), non-volatile acids and oil-in-water emulsions and applications where high temperature processing causes thermal degradation of the process flow. MD can be used for the treatment of textile industry wastewater that is contaminated with dyes.

Petro Sep has developed AQUA-SEP™ that is based on the VMD principle for separation.

Vacuum Membrane Distillation (VMD)

VMD is a significant variant of the MD process. VMD is potentially the most efficient MD configuration, since there are no heat losses through the membrane and mass transfer resistance is reduced to the minimum. VMD is considered as a better option than DCMD for the desalination of high feed salt concentrations since menbrane fouling in VMD, is usually low and can be controlled through chemical or water wash. VMD main advantage is the relatively low-conductive heat loss compared to DCMD.

Vacuum Membrane Distillation (VMD)

VMD can be applied to the treatment of aqueous streams for recovering purified water or for extracting specific volatile compounds. Some examples of VMD applications could be seawater desalination, treatment of the reject stream of reverse osmosis systems, treatment of dye solutions, concentration of sugar solutions, arsenic removal from water, waste water treatment by removal of heavy metals, mine waste water treatment, and oily waste water treatment.

Pervaporation PV

Pervaporation (PV)

In PV, the mirror component in the feed stream is seprated from the bulk by preferential transportation through a semi-permeable barrier by its partial vaporization. Separation of azeotropic, close boiling, isomeric or heat sensitive liquid mixtures, recovery of volatile organic compounds (VOC), organic/ organic sepration, recovery of trace concentrations of organic pollutants from industrial effluents and solvent dehydration are the major areas of application of PV process.

Petro Sep has developed VOC-SEP™ and AZEO-SEP™ that primarily utilize PV or possibly VP for separation.

Vapor Permeation (VP)

VP,a process similar to pervaporation, is a membrane technique siutable for concentation or efficiant sepration of valuable compounds, present in the form of saturated vapor in the feed. VP has advantages over PV. PV membranes are in direct contact with the liquid feed. This might cause membrane swelling and increased concentration polarization. In contrast, the VP membrane is in contact with vapor and the membrane stays uneffected, thus enhancing its life. Also, selectivity values are higher in VP but flux is lower compared to PV.

Conventional Filtration (MF/UF/NF/RO)

Pressure driven filtration membrane are classified based on their pore sizes and their suitability for the relevant applications to different categories. These categories are Micro-filters, Ultra-filters, Nano-filters and Reverse Osmosis filters.
