There are many different methods of ballast therapy offered by system creators. Some are more suitable to different ship types than others and a few more suited to the operating profile belonging to the ship. Both these considerations along with type-approval status and of course cost and availability needs to be factors taken account connected with when choosing.

Before thinking about the system technology itself it's worth considering the dilemma of filtration. Most of the systems available on the market have a filter included during the system but some will not. There will be a qualification of filtration provided because of the strainers at the ballast intake but that is definitely to protect the pumps and prevent piping blockages and not considered in the treatment.

The cause for filters being used is usually to assist in meeting your IMO’s D2 discharge regular which requires that taken care of ballast must contain:

fewer than ten viable organisms more than or equal to 40 micrometres in minimum dimensions per cubic metre;
less than ten viable organisms not as much as 50 micrometres in minimum dimension and more than or equal to 12 micrometres in minimum measurement per millilitre.
It stands to purpose that if such organisms might be removed by filtration for the outset then meeting the discharge standard is merely problematic due to lesser organisms growing whilst held inside ballast tanks.

Filtration also removes sediments that may both diminish the healing efficacy (especially in UV systems) and cause develop in the ballast tanks which adds needless more weight to the ship and which often can also provide ideal conditions for organisms to live on and grow.

On the actual negative side, filters enhance the expense of the procedure and need regular backflushing to counteract blockages and thus slower the intake of ballast. Another argument that manufactured against filters is the very small mesh width of 50 micrometres or less can easily be enlarged over time by the action of sediment and definately will thus eventually become inadequate. The microscopic mesh size would make any such degradation almost impossible that will detect by sight.

Couple of systems employ hydrocyclone technology because method of removing greater solids. In these programs, the water is pumped to some specially shaped chamber exactly where a vortex is induced because of the flow. Sediment and some organisms is going to be channelled away from the lake which continues on its method to the next treatment phase.
