Reverse Osmosis Demonstration. Click reload to rerun demo please
This demo shows how water flows through the RO unit. 1. Treated water flows through the pre-filter 2. The water is then forced (this process is called reverse osmosis) through the membrane. Water that does pass through is called product water. Water that is rejected is called reject water. The dissolved solids are then washed to a drain where the product water is stored in a holding tank. The ratio is 2 to 1 i.e. for every 3 gallons of water 2 are rejected by the membrane. When you access this water at its tap it comes from the holding tank and then through the final carbon block filter before its final destination at the tap.
