Biological odor systems deliver long-term solution for North Carolina wastewater utility

August 28, 2012

KINGWOOD, Texas — Envirogen Technologies, Inc., an environmental technology and process solutions provider based in Kingwood, Texas, has been awarded a contract to supply two biological odor control systems as part of a Western Wake Regional Wastewater Management Facility (WWRWMF) construction initiative, managed by the Town of Cary, N.C., and its municipal partners — the towns of Apex, Morrisville and Holly Springs, N.C.

The two systems will utilize Envirogen’s proven biofiltration technology to remove odors and 99% of hydrogen sulfide from air at the wastewater operation’s West Cary and Beaver Creek pump stations. The West Cary site will feature Envirogen’s new BTF-4500 modular vessel design, while the Beaver Creek site will receive a custom-designed built-in-place biofilter. Envirogen will also provide on-site customer support and training to assist in start-up, and a 10-year warranty covering media life.

According to Robert L. Loken, vice president, Product Management and Great Lakes Region for Envirogen, the two systems illustrate the company’s ability to design and build high-performance, low-cost systems that are tailored to specific customer needs.

“We’ve long offered a full range of system sizes and options, from smaller modular systems up to large, custom built-in-place installations,” Loken said. “The introduction of the BTF-4500 to our odor control product line allows us to offer the functionality of two treatment systems – biotrickling for H2S and biofilter for further odor reduction – in a pre-fabricated fiberglass vessel that provides the same reliable, low-cost performance and design excellence that Envirogen is known for. As always, the customer wins by getting just the right system to best meet all their requirements.”
