Reverse Osmosis is a process in which dissolved inorganic solids (such as salts) are removed from a solution (such as water). This is accomplished by household water pressure pushing the tap water through a semi permeable membrane. The membrane (which is about as thick as cellophane) allows only the water to pass through, not the impurities or contaminates. These impurities and contaminates are flushed down the drain.

Ultimately the factors that affect the performance of a Reverse Osmosis System are:

  • Incoming water pressure
  • Water Temperature
  • Type and number of total dissolved solids (TDS) in the tap water
  • The quality of the filters and membranes used in the RO System (see operating specs)

Thin-film composite membranes (TFC) are semipermeable membranes manufactured principally for use in water purification or water desalination systems. They also have use in chemical applications such as batteries and fuel cells. A TFC membrane can be considered as a molecular sieve constructed in the form of a film from two or more layered materials.

TFC membranes are commonly classified as nanofiltration (NF) and reverse osmosis (RO) membranes. Both types are typically made out of a thin polyamide layer (<200 nm) deposited on top of a polyethersulfone or polysulfone porous layer (about 50 microns) on top of a non-woven fabric support sheet. The three layer configuration gives the desired properties of high rejection of undesired materials (like salts), high filtration rate, and good mechanical strength. The polyamide top layer is responsible for the high rejection and is chosen primarily for its permeability to water and relative impermeability to various dissolved impurities including salt, ions and other small, unfilterable molecules.

Test Condition:
  1. Test under the condition that the water temperature is 25o C, the concentration of NaCI is 500ppm, PH is 7.5, and the above recovery and operate pressure.
  2. The water production of one membrane is on the balance of +- 15% of the average water production.
  3. The rejection is at least95%

Lower operating costs with condensate recovery and higher water reuse

As an industrial customer, you are always trying to reduce water and energy costs, improve process efficiency, and meet stringent discharge limitations. Industrial membranes from FS-TFC can help you:

  • Reduce salinity and chemical oxygen demand (COD)
  • Purify oily effluents
  • Remove chemical contaminants
  • Recover acid steams
  • Clean-up hot condensates
  • Pre-concentrate streams prior to evaporator
  • Reduce wastewater volumes by increasing water reuse


Meetec Gold Membranes are high quality membrane with extended life span and provide you with pure drinking water. These membrane are capable of removing various types of inorganic compounds from water. It is also effective in removing contaminants from the water along with optimising the amount of water getting rejected.
