What is a reverse osmosis membrane?
There are various different definitions that can be given to the word membrane, one definition is- ” An intervening phase separating two phases and/or acting as an active or passive barrier to the transport of matter between phases” (European `society of Membrane Science and Technology) Another definition is ” an inter phase separating two homogenous phases and affecting the transport of different chemical components in a very specific way” (Prof Solt, School of Water Sciences, Canfield) The final definition of a membrane is – a material that only allows some substances to pass through easily than others, this would be substance of a smaller size than the permeability of the membrane. This in turn is the basis of the separation process. Membrane structure is an important aspect of the membrane; the main objective of the manufacturing of membranes is to create a product that can withstand a good proportion of mechanical strength. It is also important that the membrane can maintain a hig
