Applications: Drinking water purification

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 TFC reverse osmosis membranes
  • a reverse osmosis (RO) filter which is a thin film composite membrane (TFM or TFC)
  • optionally a second carbon filter to capture those chemicals not removed by the RO membrane.
  • optionally an ultra-violet lamp is used for disinfection of any microbes that may escape filtering by the reverse osmosis membrane.
