Iron Removal Systems / Iron Filters:
Most iron filtration systems operate on the principle of oxidizing the iron (oxidation) to convert it from a ferrous (dissolved or soluble) to a ferric or (undissolved state). Media based Water filters are the most widely used in removing iron. Its popularity comes from its versatility due to the various media products available and the process involved with each media. In the ferric state, iron can be filtered easily by media filters. Care must be taken when considering iron removal advice for a different place or water source. Each type of treatment has its own strengths and weaknesses. Most application failures are caused simply by not selecting the right equipment for the water conditions present & lack of flow in backwash or a lack of frequency of regenerations. Low pH levels when using filters are another reason for unsatisfactory results.
As in the selection of equipment, It is important to follow manufacturers’ recommendations regarding flow rates, backwash rates, water temperature, pH levels, alkalinity, dissolved oxygen content, maximum iron input levels, water temperatures and any other application limitations that the manufacturer has noted in order for the equipment and media to deliver their best result as designed.
Iron in water in the reduced form is converted to the ferric compound by oxidation and these are removed by filtration alone or by sedimentation and filtration. The rate of oxidation of ferrous iron by aeration is slow under conditions of low pH and is fast under high pH conditions. The rate of precipitation and filtration are accelerated in practice by contact and catalysis. Water is allowed to trickle over coke or crushed stone. The deposition of hydrated oxides of iron and bacteria on the contact media is believed to act as catalysis which accelerates the oxidation of Iron.
This Iron Remover uses atmospheric air to oxidize the iron and sulphur (hydrogen sulphide) in your water and then removes it in a filter bed designed to capture the oxidized material. Its operation is completely chemical-free. It is a complete system for iron removal that is intended for use on private wells that contain up to 8 ppm iron and 4 ppm sulphur. For best results, water pH should be between 6.50 and 8.50.
