Indian RO Advantage

Around the world, household drinking water purification systems, including a reverse osmosis step, are commonly used for improving water for drinking and cooking.
Such systems typically include a number of steps:

  • a sediment filter to trap particles, including rust and calcium carbonate
  • optionally, a second sediment filter with smaller pores
  • an activated carbon filter to trap organic chemicals and chlorine, which will attack and degrade thin film composite membrane reverse osmosis membranes
  • a reverse osmosis filter, which is a thin film composite membrane
  • optionally, a second carbon filter to capture those chemicals not removed by the reverse osmosis membrane
  • optionally an ultraviolet lamp for sterilizing any microbes that may escape filtering by the reverse osmosis membrane
  • latest developments in the sphere include nano materials and membranes
