Chemical dosage eliminates problems with chlorine and lime in the feed water
Chemical dosage as a pre-treatment eliminates problems with chlorine and lime.
Chlorine in the feed water (eg in the UK) destroys the membranes in a RO installation. To prevent this, we dispense antichlores. Antichlores consist primarily of metabisulphite (SMBS), which also has a preservative effect during standstill periods.
Guldager use a special antique chalk, which is
- Stable over a longer period of time
- Economical in use
Lime in the feed water precipitates on on the membranes of the RO installation. This precipitation will quickly reduce the membrane efficiency. To prevent lime coatings and prolong the life of the membranes, we dose antiscale. Antiscale binds calcium and magnesium into the water so that it does not precipitate on the membranes.
- Effective for many water qualities
- Low operating costs
- The need for cleaning the membranes is significantly reduced
- Approved for drinking water in the UK
