Membrane Technology

Membrane Technology is a general term for a variety of separation processes, including micro-filtration, ultra-filtration, nano-filtration, and reverse osmosis.  The benefits of Membrane Technology is that is a chemical-free process requiring relatively-low energy consumption and that can take place at low temperatures. 
 
Membrane technology is often used for processing groundwater, surface water, and wastewater, in which a semi-permeable membrane is used to allow water to flow through the membrane while preventing the passage of suspended and dissolved solids and other undesirable substances. 
 
The mechanisms used in membrane technology can be high pressure, a concentration gradient on both sides of a membrane, and the use of electrical energy.  Most simply put, membrane technology is used when you want to remove suspended and/or dissolved solids including salt, sugars, proteins, fats, viruses, macro-molecules and more from a liquid solution. 
 
Membrane filtration has a number of benefits over other water purification techniques: 

  • The process can take place while temperatures are low, making this a good choice for the treatment of heat-sensitive matter.
  • The process requires less energy consumption, with most of the energy required for pumping liquids through the membrane at the appropriate pressure.
  • The process can easily be expanded.

    • Depending on your application's requirements, Watertronics can select the appropriate Membrane Technology and provide a complete solution to meet your needs.
