Welcome to Marine-San.

Marine-San has developed a P.O.D.-V.P.M.F. (which stands for “Pneumatic, Oxygen, Digester, - Variable,  Pore, Micro, Filter.”  system), which is a backwashable micro filter system for Commercial and larger vessels.

Marine-San is the perfect solution to your vessel toilet and marine waste treatment needs. It is manufactured and sold here in Australia by Gradon Marine.

Gradon Marine began manufacturing the Marine-San Onboard Sewage Treatment System to meet the demand for Grade 'A' Sewage standards in Australia (MARPOL 159 (55) 9010) and US Coast Guard Class II.
