Reversible cation-exchange membrane desalination (RCIX-MEM) is a useful technology that offers significant benefits for any company/industry involved in desalination of saline water. Reverse osmosis (RO) is the most common technology used for desalination of saline water but there are major problems with it, such as scale formation, disposal of brine and high costs. RCIX-MEM technology, in addition to its ability to address these concerns, has the self-sustaining ability as it does not require any external abilities of regenerant chemicals.

Advantages:

• It does not require pretreatment required and no chemicals are required to be added to deal with scaling or regenerate the membrane
  
• It gives higher yield of product water and lower brine
  
• It is self-sustaining, low on costs and overcomes the problem of scaling
  
• It is more efficient and effective than reverse osmosis

Applications:

Water pumping and purification systems, water filtration system, desalination and purification system, and water treatment or waste water recycling.

Status of intellectual property (IP):

Utility patent filed in November 2009
