    Sulfree Basic Molecule

  • About Sul-FreeSul-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 H2S than the standard triazine product on a w/w basis.Sul-Free has also shown capacity to scrub organic compounds such as benzene.

  • TOXICITYSulfree is synthesized from ingredients which are used in food and food adjutants. Found in 21 CFR 182.60, 176.200,178.3400Aquatic toxicity is very low, LC-50/96 for rainbow trout is 270 ppm. ( as WS-1500 concentrate ) At use levels, toxicity is extremely low. This chemistry at use concentrations does not harm bacteria in the system. Sul-Free is non-corrosive, easy to handle and apply, safe to use.

  • CorrosivitySul-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.

  • BiodegradationSulfree 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.

  • Mass balance of Sul-Free / Hydrogen Sulfide Biodegradation

    Sul-Free + Hydrogen Sulfide 7 CO2 + 2 CH4 + 1 NH3 + 6H20 + 1 S

    For wastewater treated with Sul-Free at 3 gallons of Sul-FreeWS 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.
