  • Pre-filtration: Contaminants are removed from water during the pre-filtration process. This is usually done through a sediment or carbon filter to eliminate particles, dirt, and debris from the water.
  • Reverse osmosis: The water is then passed through a reverse osmosis membrane, which removes ions, molecules, and larger particles by forcing the water through a very small semipermeable membrane. This process purifies the water by removing up to 99% of all contaminants.
  • Drainage: The wastewater created from the reverse osmosis process is then diverted to a drain.
  • Storage: The purified water is stored in a storage tank until ready for use.
