Reverse Osmosis is a filtration system designed to remove dissolved solids, organic and inorganic forms, that a water softener cannot. RO removes metals like aluminum, copper, lead, chromium, etc. It also removes inorganic forms such as nitrates, phosphates, chlorides, and sulfates. RO forces water from your home’s supply through the RO membrane. This membrane contains thousands of tiny holes, just large enough to allow water molecules to pass through. Anything bigger than a water molecule is rejected and cannot fit through the membrane. C and J Water offers a premium 4-stage Reverse Osmosis System that is a great solution for water used for drinking and cooking. C and J Water is passionate about providing Central Indiana families with high-quality water right from the tap.
