Iron removal
media
Media designed to remove iron exceedances from water, usually well water. Thanks to their long operating life, iron removal media are extremely economical to use. They effectively eliminate iron compounds dissolved in water, in most cases additionally reducing manganese content. Depending on a selected type, they may require chemical regeneration.
Ironit media
Ironit is a natural dolomite and quartz dolomite medium with iron and manganese removal properties, characterised by high efficiency of water treatment, long operating life and economical use. It reduces the colour and corrects the smell of treated water, removing small amounts of hydrogen sulphide and ammonia. A water treatment process based on the Ironit medium requires water pre-aeration with a venturi or compressor. Thanks to aeration, iron reacts with oxygen and gets precipitated. The Ironit medium may only be used in installations with a non-diaphragm hydrophore tank.
Birm media
A natural catalytic Birm medium intended for removing iron and manganese from water. Water treatment with the Birm medium requires water pre-aeration, so it cannot take place in water installations with a diaphragm hydrophore tank. The mixture is characterised by significant tolerance to temperature changes and long operating life. Birm catalyses oxidation of iron dissolved in water and thus enables its removal. The medium does not dissolve, so it does not need to be refilled regularly, and its regeneration is performed only by means of water backflow.
Greensand Plus media
Greensand Plus medium removes iron and reduces manganese dissolved in water. Additionally, it eliminates radium, arsenic and hydrogen sulphide. Greensand is manufactured by processing glauconite, which is a natural and environmentally friendly component. The main task of the medium is oxidation of iron cFe(II) and manganese Mn(II) to higher oxides. This process results in formation of insoluble suspensions, which can be removed by backwashing. The Greensand Plus iron removal medium is regenerated with potassium permanganate solution and needs regular refilling.
