Reverse Osmosis Filtration Process

1. The contaminated drinking water flows through a filter where most of the larger particles are removed.
2. The second stage of this process is a carbon filter where contaminants such as chlorine and some taste and odors are taken out.
3. The third stage and perhaps the most important one is the semi-permeable membrane. The water molecules are forced by normal water pressure to the surface of the semi-permeable membrane where the unwanted contaminants are collected and the purified water permeates the membrane and is routed to a special holding tank. The dissolved and un-dissolved contaminants that do not flow through the membrane are rinsed off and discharged to the drain.
4. The fourth stage is an additional carbon filter to remove any taste and odors and enhance the flavour of the water.
