Process Description
Bilge water is taken from the vessel bilge tank via a slow-revving positive displacement pump to
prevent further emulsi cation. The oily bilge water is fed into the rst stage High Viscosity Oil
Removal (Hi-VOR) system and initial sludge oil separation takes place. Free oils are removed via a
high matrix oleophilic coalescing pack which draws oil to its surface creating large globules of oils
that are oated to the top of the tank. This waste oil is then discharged to the waste oil tank. The
second stage 20 micron coalescer cartridge system coalesces the remaining free oils. Emulsi ed oils
enter the nal AGM stage for treatment.

Our engineered Advanced Granular Media (AGM) is a specially formulated organoclay and has
extremely high adsorption properties that remove emulsi ed oil, grease and low soluble organic
compounds from waste water streams. The AGM is very e cient due to the large surface active areas
and can adsorb up to 60% of its own weight in organic contaminants, in comparison to only 2-5% for
granular activated carbon. Designed to be quick acting, the AGM is both hydrophobic and oleophilic
making it extremely e ective. This remarkable adsorption can produce continuous and reliable
e uent below 5ppm. With no cleaning cycles, no back wash discharges and no extra downtime for
replacements or the use of chemicals, running costs for our system are kept to a minimum.
