## Description

The **OlioSep™ DNAPL 3-Phase Separator** simultaneously recovers light NAPL, treats groundwater, and collects dense NAPL in a single vessel — the ideal first stage for chlorinated solvent, coal tar, or creosote remediation.

Custom-engineered at ERE's Montréal facility from 304 stainless steel (316 SS optional), every unit ships skid-mounted, anchor-footed, and freight-ready with a conical hopper bottom for positive DNAPL collection.

## Key Features

- **Conical hopper bottom** — positive DNAPL collection through a dedicated bottom port
- **Hexagonal coalescer media** — high-efficiency, accelerates fine droplet separation
- **Adjustable oil skimming weir** — continuous LNAPL removal to a dedicated collection port

- **Stainless construction** — 304 SS standard, 316 SS optional, welded SS frame on bolted anchor feet
