Coalescing Filtration Skid
Two-stage coalescer/separator skid removing fine dispersed hydrocarbons and solids from water down to single-digit ppm — a polishing stage after gravity separation.
Quick Answer
A Coalescing Filtration Skid is a two-stage polishing system that merges fine dispersed oil droplets on coalescing media and separates them from the water stream, while pre-filters remove solids. It reduces oil-in-water to single-digit ppm downstream of a gravity separator, and is available for rental or purchase.
System Overview
The skid combines a solids pre-filter with a coalescer/separator vessel. Coalescing media merge fine oil droplets too small to separate by gravity into larger droplets that rise and are collected, polishing the water to single-digit ppm.
Design & Construction
Pre-filter housings, coalescer vessel with replaceable elements, differential-pressure monitoring, and a compact skid frame. Offered for short-term rental during turnarounds or as a permanent installation.
FAQ
Is this available for rental?
Yes — the coalescing skid is one of our rental units, ideal for turnarounds, commissioning, or temporary remediation. Mid-term and purchase options are also available.
Where does it sit in the train?
Downstream of a CPI or API separator as a polishing stage, ahead of discharge, reinjection, or further treatment.
