Membrane Technology

 

For which applications?

Various membrane processes are viable technologies for numerous water and wastewater treatment applications. Due to wide applicability of the membrane technology it can be a part of an efficient solution for the treatment of challenging wastewaters in the various industrial sectors such as chemical, pharmaceutical, textile, refining as well as food and beverage industries. Examples of possible applications:

Microfiltration (MF)

Removal of suspended solids and bacteria from Wastewater, clarifying water.

Ultrafiltration (UF)

Virus removal, hemicellulose separation, colorants (such as indigo) removal from wastewater.

Nanofiltration (NF)

Removal of divalent ions (e.g. sulfates), hardness from water, synthetic dyes, organic micropollutants (active pharmaceutical ingredients, pharmaceutical residues, pesticides).

Reverse osmosis (RO)

Removal of salts (sodium chloride, NaCl) and persistent organic pollutants from water or wastewater.

 

How does it work?

Membrane technology (pressure-driven membrane separation) utilizes semipermeable membranes (polymeric or ceramic) to remove unwanted impurities from water or wastewater (Fig.). Membrane acts as a semipermeable barrier, which restricts the flux of various components due to their molecule size (size exclusion), chemical nature (such as hydrophilicity or hydrophobicity) or electrical charges. Membrane separation processes operate usually without heating and therefore use less energy than conventional thermal separation processes such as distillation. In many cases, such as in food and beverage applications, the both fractions produced in membrane filtration called as permeate (stream passing through the membrane) and concentrate (stream retained by the membrane) can be utilized.

How can InOpSys help?

Based upon our extensive background in various membrane technologies and many years of academic research we can screen and determine the appropriate membrane technology (pressure driven or other membrane technologies) for your specific wastewater. We can customize the treatment process based on your waste stream and combine membrane technology with other wastewater technologies, if needed. Finally we design, construct and operate a full flexible, modular and mobile (ATEX certified) unit, to treat your wastewater on-site.
