Drinking water limits: 125 mS/m (i.e. 1250 µS/cm)
- Increased formation of deposits, salty or other taste of water
- Damage to equipment, formation of deposits, corrosion
Removing increased water conductivity
- Principle: reverse osmosis, ion exchange
Conductivity is an indicator of the total amount of dissolved minerals contained in water. Rainwater has low conductivity, wastewater or rivers near their mouth, higher. Higher conductivity does not in itself cause health problems. On the contrary, mineral water (i.e. water with high mineral salts content) is often considered as healing. In terms of long-term consumption, however, too mineralized water is not ideal.
In industry, high conductivity water causes many problems. It has higher corrosive and incrustating effects, it clogs sensitive devices and degrades products.
For industrial demineralisation of water, reverse osmosis is commonly used, capable of removing around 99% of all minerals. Reverse osmosis water achieves conductivity of about 10-20 μS/cm. If lower conductivity is required, an ion exchange demineralisation cartridge can be included after reverse osmosis. This can reduce the conductivity to less than 1 μS / cm.
