1 “The interaction between sulfur and the π orbitals of the C=N links is far greater than anything which occurs with oxygen or nitrogen substituents.” “organic sulfur compounds”,page 54 Sulfree™ Basic Molecule

2 About Sul-Free™ Sul-Free™ represents a new imine complex that offers significant advantages in treatment. It specifically targets acid gases including hydrogen sulfide, organo-sulfur compounds and mercaptans. The Sul-Free™ molecule has demonstrated much higher capacity than current science. In recent hydrogen sulfide gas scrubbing trials, Sul-Free™ captured 20 times more H 2 S than the standard triazine product on a w/w basis. Sul-Free™ has also shown capacity to scrub organic compounds such as benzene.

3 TOXICITY Sulfree™ is synthesized from ingredients which are used infood and food adjutants. Found in 21 CFR , , Aquatic toxicity is very low, LC-50/96 for rainbow trout is270 ppm. ( as WS-1500 concentrate ) At use levels,toxicity is extremely low. This chemistry at use concentrations does not harmbacteria in the system. Sul-Free™ is non-corrosive, easyto handle and apply, safe to use.

4 Corrosivity Sul-Free™ solutions are isotonic with the pH of concrete. It is not corrosive to wastewater piping systems. As it removes the hydrogen sulfide the corrosive environment to the system infrastructure is abated. In well-bore and pipe applications corrosion is reduced due to acid gas capture. The Sul-Free™ molecule due to its structure may demonstrate anti-corrosive properties. In handling Sul-Free™ there is no need for special chemical resistant pumps, tanks or plumbing.

5 Biodegradation Sulfree™ biodegrades under anaerobic conditions to methane, carbon dioxide and water. This leaves virtually no solids, no salts which produce EC ( electrical conductivity ), no nitrates. Sulfree™ does not generate Oxides of Nitrogen ( Nox) in its use or biodegradation. Carbon Monoxide ( CO ), Particulate Matter (PM2.5), Particulate Matter ( PM10) are not generated by this technology.

6 Mass balance of Sul-Free™ / Hydrogen Sulfide Biodegradation Sul-Free™ + Hydrogen Sulfide  7 CO CH NH 3 + 6H S For wastewater treated with Sul-Free™ at 3 gallons of Sul- Free™WS 1500 per million gallons of wastewater, the mass balance of constituents prior to treatment would be 2.3 lbs Carbon Dioxide, 1.69 lbs of Methane, 0.9 lbs of Ammonia, 5.7 lbs of water and 1.69 lbs of Sulfur. Under aerobic conditions, the Sul-Free™ molecule can catalytically regenerate which allows it to be a net consumer of ammonia.
