The inTank BWTS does not ? lter the ballast water on uptake, which is different than most in-line systems. To ensure consistent and effective kill of target organisms and pathogens, the Concentration-Time (CT) treatment approach is utilized. The recirculation capacity enables monitoring and re-dosing to meet the target combination of oxidant dose and hold time. The ability to dose in-tank and re-dose ensures effective treatment regardless of or- ganic and inorganic loads in the ballast water. And, while those advantages translate into real operational gains – and pro? ts – the Envirocleanse BWTS delivers in many more ways, as well.
