PARK RIDGE, Ill., September 17, 2025 - Interra Global will exhibit at WEFTEC 2025, the 98th annual Technical Exhibition and Conference of the Water Environment Federation, at McCormick Place in Chicago. The exhibition is open September 29 to October 1, the closing three days of a conference that begins September 27. The Chicago show is Interra Global's second WEFTEC, after a first exhibit in New Orleans in 2024, and its first in the company's home state. It is also the second show of the company's fall season, the week after RNG Works in Nashville. A team of six will staff the booth through the three exhibition days. From booth 5708, the company will present its hydrogen sulfide (H₂S) removal line in the order a plant meets the problem. FerroSorp® DGR is the digester additive: an iron hydroxide powder dosed into anaerobic digesters, those at wastewater treatment plants among them, where it binds sulfur before it can leave in the biogas as H₂S. FerroSorp SK and SLH H₂S removal media are the pellets that take H₂S out of the gas itself, SK from high-humidity gas and SLH from gas at low relative humidity. The VAV™ H₂S Scrubber Vessel is the mobile roll-off vessel that Interra Global designs and builds to hold the pellets, and digester gas at wastewater treatment plants is among its typical applications. The booth's other product answers a second contaminant in the same gas. sSORB® White Silica Gel Beads go into siloxane removal beds on landfill gas and digester gas, where the gel captures siloxanes before the gas reaches an engine, a turbine, or a catalyst. Interra Global's technical staff take media selection questions for a given system. "WEFTEC puts the wastewater industry under one roof, and we want it to know that our H₂S removal media, our vessels, and our sSORB silica gel are available for its use. We will be at booth 5708 on all three exhibition days to show where each one fits at a plant that runs digesters," said Gary Byers, Director of Interra Global's Biogas Division. The Water Environment Federation bills WEFTEC as North America's largest annual water quality exhibition, a five-day conference of education and training for water quality professionals that closes with three days of exhibition. On the exhibition floor at McCormick Place, Interra Global's booth will address two contaminants in digester gas, H₂S and siloxanes, among the water sector's equipment and service suppliers. Attendees who want a set time at booth 5708 during the exhibition can arrange it with Interra Global's sales team at [email protected].
