Micro-Kill UV reactor Operational range of one UV-chamber is 20 m 3 /h - 167 m 3 /h.

A combination of UV-chambers is accepted under the following criteria: - Chambers mounted in parallel (vertically or horizontally) - The inlet and exit from the manifolds are on opposite sides - The construction of the chambers (i.e. dime nsions, form and material) is exactly the same - The construction of the two manifolds (i.e. dimensions, form and material) is exactly the same.Any other construction that does not fit to the above mu st be approved by DNV before allowed to be considered as part of this Type Appr oval Certificate. UV-intensity meter Acceptable range: 100 - 2500 W/m 2 Measured UV intensity below 100 W/m 2 implies that the ballast water is not treated in accordance with this Certificate.
