Sea Horse has developed its newest units to meet the most recent IMO Sewage Treatment Systems regulations (IMO Res. MEPC.115(51), Reg 9.1.1, and 33 CFR 159.015). Our customers have enjoyed the trouble-free operation of the
Sea Horse since the initiation of the IMO resolution in 2010.

Our units use a high-pressure discharge pump, and a media filter with a large surface area, to ensure its maximum life. In addition, our control panel removes the guesswork from the operator to ensure trouble-free operation.
