Reverse osmosis

The cross-flow filtration membrane technology is used to physically separate from an aqueous solution even extremely small soluble substances (ions, molecules), whose size is measurable in nm (nanometers).
The degree of filtration depends on many factors:

  • the size of the pores of the membrane and the material of which it is made;
  • the chemical characteristics of the fluid to be treated;
  • operating parameters (temperature, pressure, pH, etc.);
  • the fluid dynamic regime (increasing or decreasing the circulation velocity of the fluid that flows tangentially to the surface it is possible to alter the performance of the membrane in terms of rejection).

Reverse osmosis membranes are the most selective available, since they can also separate monovalent ions and organic substances with a low molecular weight (in the order of 100-150 D). In fact, most solutes are retained and purified water is obtained beyond the membrane.
