It was never going to be realistic to expect treated ballast water to have zero viable organisms on discharge.The G8 guidelines that define the type approval process for ballast water treatment systems were initially agreed at the IMO before any systems had actually been developed.The IMO had already been working on the issue of invasive species being transferred around the world in ballast water for a couple of decades. It was on the radar back in the 1970s. At MEPC 31 in 1991…
