Controlling odors is one of the most important ­— and often one of the most challenging — aspects of wastewater treatment. Foul odors are typically the main source of complaints, igniting objections from neighbors and not only inconveniencing, but potentially endangering plant workers.

In an effort to combat plant foul odor issues, Anue Water Technologies has launched customizable Geo-Membrane coverings designed to eliminate those foul odors completely. The company employs technology leveraging its existing ozone and oxygen generation and related systems for the elimination of odor, corrosion and FOG in municipal and industrial wastewater.

“Anue is pleased to introduce this innovative, thoroughly tested and proven technology in the U.S., Canada and Caribbean region,” says Paul Turgeon, Anue CEO. “These Geo-Membranes provide many more municipal and industrial customers an even lower-cost approach to sustainable odor control.” 

This technology consists of high-strength, flexible Geo-Membrane cover systems fitted with pockets that contain replaceable filter media. They are custom-engineered to fit each application and ensure exceptional broad-spectrum odor control. According to Turgeon, they can be used in practically any wastewater treatment application, such as headworks, tanks, sludge pits, open channels, vessels, manhole covers, truck bays, vertical vents and fugitive emissions from vent covers.

The 1/32-inch membrane (13/16 inch with filters inserted) is supported by a cable grid and batten bars above the surface, making it unaffected by aeration, changing water levels, foaming, bacteria and other common issues. This allows installation in even the toughest of locations. Custom access and viewing ports allow for uninterrupted maintenance. The filter design is engineered to allow gases and water to flow freely through the filters while they capture the odor-causing contaminants. Gas-specific filters for hydrogen sulfide and ammonia can be combined in the system for optimum control, even under grates and manhole covers. The membrane has an expected lifetime of over 10 years even in harsh environments, and the specialty engineered filter inserts last 9 to 18 months depending on emissions levels.

According to Turgeon, the filters are designed to remove all malodors, helping eliminate the need for chemicals or scrubber equipment and greatly reducing employee hazard and OSHA risks.

“We see this as a system that can pay for itself within 6 to 12 months,” he says. “This broadens Anue’s product line to a wider range of odor control solutions.” 760-213-7739; www.anuewater.com
