A Summary on Wastewater Odor Control Equipment

When an RV park in Granby, Colorado, had a force main that began to go septic through municipal sewer water, it caused wastewater odor issues that made the park less enjoyable for visitors and was in desperate need for municipal wastewater treatment. Andrew “Hopper” Becker, superintendent of operations for Granby Colorado Sanitation District, insisted on finding a sustainable solution to the problem. The use of the wastewater odor control equipment FORSe oxygen injection system was adopted and tested for six months. The results have been more than satisfactory and the unit is still in use today. There are plans to expand the RV park and this unit is equipped to handle the extra work.

An Excerpt on Wastewater Treatment Service at Granby, CO

Located 30 miles south of Rocky Mountain National Park, Granby RV Park is a place for RV owners and other nature enthusiasts to convene and enjoy the outdoors. To ensure campers, whitewater rafters and other frequenters enjoy the vast expanses the area has to offer, tackling a less enjoyable issue at the Granby RV Park, specifically an odor issue, was at the forefront of Granby Sanitation District’s agenda and what led to them seeking municipal wastewater treatment through Anue Water’s wastewater treatment service.

The Granby RV Park had a force main approximately 9,000 feet long, which was going septic through municipal sewer water, causing a massive odor problem and needed municipal wastewater treatment. Andrew “Hopper” Becker, superintendent of operations for Granby Colorado Sanitation District, was determined to find a sustainable solution to the odor control problem. The sustainable route is not always the easier route, but he was not alone in this desire to achieve it. Since RVs have high-efficiency appliances, there is an incredibly high BOD and organic flow coming out of RVs and holding tanks, which contributes to the problem. Initially, a recommendation for atmospheric oxygen was made, but this was ultimately rejected because it would not have worked for this particular site. The use of the Anue Water FORSe oxygen injection system for wastewater treatment service with remote digital telemetry was adopted and tested for six months instead. It is still operating successfully today.

“As the developer started putting a design together to pump the sewage over all of that distance to the sewer plant, we started thinking about the possibility of severe H2S production and septicity…other problems associated with long resident times,” said Hopper about the beginning stages of mitigating the odor control issue. “It is directly my responsibility to ensure compliance to the discharge permit, and I take that seriously to protect the public health and the environment.”

A second major goal of the municipal sewer water project was to ensure the best possible water quality without adding additional chemicals, which could potentially become an issue in the future.

Another consideration came down to the site location, as it is not the easiest to access due to the nature of the RV park itself. The lift station pad is fairly small, as well, so chemical storage was a concern, Hopper added.

“Anue Water’s FORSe systems feature remote digital telemetry, making it safe and easy for operators to monitor and control dissolved oxygen levels,” said Greg Bock, Anue Water vice president and general manager. “The FORSe systems also has the capability of injecting ozone for those applications, which require ozone or a combination of oxygen and ozone.”
