This company sent out the tender for the cooling system in 2004. Innowac won against all the competitors. We used Innowac KI 107 which is an all organic formulated inhibitor and sodium hypochlorite as the main biocide. We used our Innowac DK-DOX in a concentration of 0.5 – 1 ppm against Legionella bacteria every 4 weeks.
Innowac Recommendation: Cooling water quality: | pH | 8.5 | | Conductivity | 2000 µS/cm | Total hardness as CaCO3
| 800 ppm | | Alkalinity as CaCO3 | 600 ppm | | Chloride | 300 ppm | | Sulphate | 500 ppm | | Iron | < 0.2 ppm | | Innowac KI 107 | 50 – 60 ppm | | Free Chlorine | 0.3 ppm |
Results:
Corrosion rate is < 0.05 mm / year and the customer is very satisfied. |
