Biofilter provides a high performance low cost odor solution
- Tom Smith
Lake Wildwood in western Nevada County, California is 60 miles northeast of Sacramento with 2,915 sewer connections.
Following construction of a new, 95 foot diameter 835,000 gallon wastewater treatment tank, the municipality decided to provide covers and odor control to minimize odor emissions that were affecting nearby residents.
The municipality selected Anua with the proven capability of the Mόnashell biofilter as the most competitive and best whole life cost solution.
The advantages of the Mónashell technology were recognized as being the high odor reduction performance across the broad range of odor emissions including reduced sulfur compounds and VOC's, sustainably through reusing oyster and mussel shells that may otherwise have become a waste, and the low life cycle cost through utilizing cost effective long life media without any nutrient or chemical addition.
The installation was completed in April 2011. Performance testing was undertaken using inlet and outlet Odalogs during the summer months which was expected to provide the worst case conditions.
Hydrogen sulfide, the "rotten egg" smell, reduction was greater than 99.5 percent. The neighbors are no longer bothered by foul smells from the wastewater treatment plant.
Do you have odors from a nearby wastewater facility that need treating?
