The Biorem systems ordered include two custom-designed biofilters and one modular biofilter using Biorem’s proprietary Biosorbens media which will be installed at wastewater treatment plants.

One Biorem system will treat 8000 cfm of air produced from equalization tanks, the second will treat 21 000 cfm of air produced from sludge holding tanks and a dewatering facility, and the third will treat hydrogen sulfide concentrations from a headworks building. The fourth Biorem system is a multi-stage biotrickling filter designed to treat hydrogen sulfide at a wastewater treatment facility's lift stations.

“While our main focus is on applying our technology in new markets, we will continue to maintain our leadership position in our core odor control business. These orders reflect that we are maintaining momentum in booking new orders for our systems and now benefiting from the US economic recovery and resumed municipal capital spending,” said Peter Bruijns, Biorem president and CEO.
