ADI has received Canadian and US patents for its SULFA-BIND^® adsorption process for reducing H₂S in gas and air streams.

• SULFA-BIND^® is proven to reduce H₂S in biogas by up to 99.98%
• It can handle H₂S up to 30,000 ppm
• It reduces H₂S to non-detectable levels (0.2 ppm)
• There is a reduction in 60 seconds or less of contact time
• SULFA-BIND^® can be regenerated and residuals are non-hazardous
• Up to 500 mg H₂S adsorbed per gram of media.
