Project in Brief

  • Project Name: Hono'uli'uli Wastewater Treatment Plant
  • Location: Honolulu, HI
  • Installation Date: May 2019
  • Source of Odors: Cake Odor Control Facility
  • System Type: Biofilters
  • Media Type: Enhanced Cell-Max™
  • H2S Removal Efficiency: >99%

The Situation

Three biofilters required outfitting with a complete odor control system, including all media, equipment and accessories.

The Solution

Parsons RCI, Inc., a local firm working with GES Biotek, upgraded the Biofilters with New York Blower exhaust fans and a Hunter irrigation system controller and spray nozzles. Parsons then filled the Biofilters with Enhanced Cell-Max™ media, an open-cell, rigid substrate coated with a proprietary formula of nutrients and adsorbents. This helps establish a healthy, thriving ecosystem of fungi and bacterial organisms to treat complex odors, VOCs, and low levels of H2S at 1/4 the weight of comparable engineered media.

A smoke test and full performance test verified that the newly outfitted system was performing to spec. The smoke tests demonstrated uniform airflow distribution throughout the Enhanced Cell-Max™ media bed on all three of the biofilter cells, which indicates that the air distribution pattern is even throughout the system.
