Whole House Iron filterRed stains are normally caused by iron in the water. You must test to determine the amount and the type of iron you have. Some types are: oxidized, soluble, colloidal, bacteria or organic-bound. All are a problem! It only takes 0.3 ppm to stain clothes, fixtures, etc.

The solution is normally a whole house water filter, specific for iron and manganese removal.

The media filter is an aluminum silicate media coated with manganese dioxide. This coating is highly concentrated with oxygen and acts as an insoluble catalyst to enhance the reaction between dissolved oxygen and the the iron compounds. In essence, the dissolved iron is oxidized at the surface of the media into a rust particle that can be effectively filtered from the water. The precipitated iron and manganese can then be easily removed from the system during backwash. No chemical regeneration is required and nothing is imparted into the drinking water.

For the filter to effectively remove iron, the pH of the raw water must be greater than 6.8. If both Iron and Manganese are present, the pH should be between 7.5 and 8.5. For Manganese removal the pH should be between 8.0 and 9.0 for best results. .

Operated under proper conditions, the filter media filter requires no chemical for maintenance and regeneration is not required. Iron removal efficiency is extremely high, with only periodic backwashing required. The filter media is a durable material with a long life and a wide temperature range.
