Pre-filtration – Chlorine protection
To ensure the microbiological requirements of drinking water, chlorine is often used – continuously or temporarily
Free chlorine is reactive and effective, but has a big disadvantage for water treatment technology. It destroys not only micro-organisms, but inevitably the membranes, too.
Free chlorine, chlorine dioxide and hypochlorite need to be eliminated before entering the Reverse Osmosis. The use of upstream activated carbon and dechlorite filters has proven to be efficient.
- Activated carbon safely removes organic chlorinated compounds
- The efficiency depends on the type of activated carbon and the contact time
- Due to the large surface a bacterial increase can be raised
- The required water quantity as well as the quantity of the organic contamination defines the size and the durability of the carbon filter
- The state of exhaustion needs to be checked continuously and the activated carbon needs to be changed annually
Your local water provider can give you reliable information concerning the drinking water quality as well as the potential necessity of chlorination.
