Step 1: Filtering
Ballast water is pumped onboard by the ballast pumps and filtered by a mechanical, fully automatic back-flushing filter.
The filter is an automatic self cleaning filter equipped with a 40 micrometer screen. The filter will remove 60 – 80 % of the organic load above 40 micrometer.
The filter is used at uptake and will when in use, automatically backflush all organic material back to the same water as where it has taken up by the ballast pumps. The filter is electrically or hydraulic driven.
