The problem of achieving oil in bilge water discharge to meet legal requirements has been solved by the Royal Netherlands Navy using Wavestream System 2 bilge filters in all relevant size craft in their fleet. Several months of testing proved Wavestream to be the solution the Navy were looking for.
Wavestream is a compact filter easily installed between the bilge pump and outlet. It removes all traces of oil or pollution from the bilge discharge water. The entire Wavestream range has been awarded Lloyd’s Register Type Approval providing verification of its effectiveness and suitability for use on all sea going vessels.
