“We take care of the sea and the seafarers”
oily water separator that actually works
Patented innovative process
Produces crystal clear water (15/5ppm).
Instead of trying to remove pollutants from the water, the OWE effectively removes the water from the pollutants.
Our simple solution process the water by two successives stages:
Stage 1: Coalescing + Settling
Of course coalescing and settling are linked each other and they are turns key in processing dirty water. But coalescing filters are well known for fast clogging and performance drop.
Therefore, In stage 1 we fit our OWE with a coarse coalescing mat to only settle the "easy to catch" floating oil. Hard to fool and easy to clean.
Stage 2: Two changes of state from effluent to vapor to clear water
Final treatment is based on two successive phase transition: oily water to vapor to distillate water.
Purpose of this stage is to break down thin and stable emulsion containing solved oil or contaminent. These effluents are generally hard to settle. This is the hard part of the job.
The OWE use wasted heat recovery from the main engine or any other wasted heat to boil the water out of the effluent at negative pressure. This steam is later condensated into a clear distillate water.
Automatic operation
The system runs automatically, and controls parameters for maximum performance.
No attending personnel to run the system.
Primary settling tank
Heavy and light phase contaminants are partially separated from water using settling and coalescing.
Small Drops (> 50 microns) of oil aggregate together at a given temperature and settle in the top part.
Contaminents are automatically detected, and drained to a dirty or waste oil tank.
15ppm or 5ppm Sensor with three-way valve.
Oil in water is continuously scrutated.
A three-way valve diverts improperly cleaned water to a tank.
In case of severe pollution, effluents can be conditioned as many times as necessary to reach an acceptable level of contamination, at no extra cost.
Clean water generator
Final treatment is based on a 2 phase transition: oily water to vapor to distillate water.
Water is removed from the effluent.
This treatment allow a very fine separation from water and polluant.
Rising concentration of the effluent is controlled by adjustable and regular drainage.

Always concerned by seafarers and caring for the ocean, He founded DAMSIA in 2017 to provide products and services that improve environmental impact of the shipping industry, thus reducing stress on seafarers, officers, and shipowner representatives.
At first Damsia focused on Oily Bilge Water and Sludges. Such waters are difficult to process ashore and build up to great quantities onboard.
