Treatment
Drinking water
Drinking water networks may have turbidity above the norm, what makes necessary a treatment facility. In many cases, the installation of a Hectron filter (between 0.5 and 3 microns) is sufficient to reduce turbidity below 1 ntu.
Hectron filters are also used for UV protection, reverse osmosis membranes or ultrafiltration units. They make it possible to improve the efficiency of this equipment and extend its life.
For these applications, choose the ACS certified version. ACS is a French certification for use in drinking water, which is recognized in the countries of the European Union.
Suitable equipment
AG AUTOMATIC FILTERS – ACS option
AG filters in ACS version are the most suitable. They have the advantage of being fully automatic, without consumables cartridges and available with very fine filtration degrees.
Benefits
- Very fine filtration
- Fully automatic
