Wastewater Treatment

I just wanted to let you know how well Sulfree is working for our facility. Since we started using Sulfree the odors from the wastewater treatment facility have become nonexistent. We've tried other hard-to-use, high maintenance and very expensive products in the past, but never with satisfactory results. Sulfree is effective, easy to use and (with minimal dosage rates) is a fraction of the cost of any of the industry standard odor reducing products on the market. Please feel free to use me as a reference.

Please be advised that the Sulfree™ product Guard has been supplying RTW is working great. We no longer smell any of the "rotten egg" smell coming from our wash tanks. Just small additions of the Sulfree™ keep the tanks from smelling offensive and create a more pleasant work environment. From all the employees at RTW, please except our thanks in solving this odorous dilemma.

Sulfree™ for Refineries

I will definetly will be ordering a barrel of the Sulfree™ 1530 in early spring when the air and liquids start heating up. The sulfree takes the pungency out of the liqids which is the offensive odor , you can still tell it's cow manure but the neighbors are no longer shooting at us. Bear in mind that's using half a gallon a day with 350 milk cows , as you have no charts or directions it's a by guess or by golly system that is being used for now. I'm hoping to be able to cut that rate down some. We sell our solids to a soil products company that composts it and mixes it with barkdust and fertilizers to make soil amendments.
