CDM and Port of Portland (Port) partnered to enhance the Ports existing aircraft and pavement deicing system at Portland International Airport (PDX). A conceptual-level design outlined a Reverse Osmosis (RO) treatment approach to remove organics and allow discharge of the treated effluent directly to adjoining water bodies. CDM designed and implemented a RO pilot test to determine and verify: basic treatment steps, quality/quantity of permeate and reject, maximum recovery and operating parameters.

A system consisting of ultra filtration, anti-scalant addition and multi-stage RO system, the pilot successfully treated PDX deicing runoff at a sustained 75% recovery. The multi-stage RO system achieved permeate quality suitable for meeting requirements for direct discharge to the Columbia Slough/River. However, it was later determined that the volume and TDS concentration of the RO reject stream at 75% recovery was too great to be effectively managed on-site.
