BWM treatment system

There are a number of approved ballast water treatment systems available and there are many more systems which are expected to be submitted for test and approval in the near future; there will be significant lead times for some of the more popular systems, particularly in the year leading up to entry into force of the BWM Convention.

When selecting a treatment system, you need to consider many factors: 
– ship type 
– max and min ballasting and de-ballasting rates
– ballast capacity 
– space required (foot print and volume)
– flexibility of location of system components
– the effects of pressure drop
– integration with existing systems
– whether it is certified intrinsically safe
– power availability 
– health and safety 
– effects on tank structure/coatings
– availability of consumables, spares and support (servicing)
– additional crew workload
– crew training 
– capital and operating cost
– system availability and delivery time.
