Most of today’s R/Os have a 4-1/2 gallon storage tank along with an automatic shutoff valve. The valve closes to shut off the water production when the tank is full. Once water is drawn from the tank, the valve reopens to produce more pure drinking water until the tank refills. More storage is available by adding another storage tank or a larger storage tank (if there is room under the kitchen sink).
The membrane production rates vary from 5 to 150 gpd (gallons per day) for residential applications. A 5 gpd membrane means that once 1 gallon of water is removed from the storage tank, it takes approximately 5 hours to reproduce a gallon of pure water. For commercial applications the range is usually 250 – 2,500 gpd.
A 24 gpd membrane means that once 1 gallon of water is removed, it only takes 1 hour to reproduce a gallon of pure water. This higher reproduction rate usually eliminates the need for more storage.
There is no waste because water rejected contains the undesired components of water which are not wanted or needed. Many studies show that these components can be hazardous to a family’s health.
Diamond Pure Water Filtration offers the most modern up to date proven R/O systems, with the higher reproduction rates and lowest waste water rejection rates available. Your drinking water would now be 95 to 98% pure for your family.
