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.
