HYDROTECH IRON FILTERS
Once installed, the chemical free iron filter requires little or no attention. It automatically removes soluble iron, sometimes called ferrous iron or “clear water”, precipitated iron, sometimes called ferric iron or “red water” and bacterial iron. It is safe and very economical because it requires none of the expensive or messy chemicals conventional iron filters use.
The chem-free iron filter features two major components, an air injector and a backwashable filter containing special media. In some applications a contact tank or an additional pressure tank may be required for the chem-free to function. The air injector adds a controlled amount of air to the water supply just before it enters the pressure tank. The air starts the iron removal process as the water sits in the tank.
