De-icing
De-ironization of water involves removing the iron from the water. According to the Drinking Water Ordinance, there is a limit value for iron of < 0.20 mg/l. The limit value for iron exists mainly because iron (and manganese) in the water causes deposits in the pipe network. For this reason, concentrations of less than 0.02 mg/l for iron should be maintained after water treatment .If there are too many deposits of iron and manganese in the pipe network, water can hardly flow through the pipes. In addition, the deposits can loosen and result in brown-colored water. You can also taste a very high iron content in the water.
Water treatment process for iron removal
There are different processes for iron removal:
- precipitation
- Flocculation
- sedimentation
- Ion exchange
We use the ion exchange process with our penta iron removal systems. With the special filter material, the dissolved iron is bound to the exchange resin . Similar to water softening , the exchange resin must be regenerated with sodium chloride (salt).
Areas of application
Our iron removal systems are generally used for well water. Groundwater often contains high levels of iron and manganese. Since there are many private water suppliers, the water should be treated before it enters the domestic water network. Iron removal using Penta iron removal systems is ideal here. The easy handling thanks to ion exchange offers many advantages. A single water filter can remove five different substances from the water ( iron , manganese, ammonium , calcium and magnesium ). Calcium and magnesium create water hardness . These substances are responsible for the lime .
Iron removal is not used for private customers who use city water. The waterworks already ensure that the tap water is free of iron and manganese. This means that further water treatment is not necessary. Only water softening makes sense for many private households, as high water hardness still occurs frequently.
