Sewer Fresh liquid odor neutralizer from Chemtron eliminates organic odors from waste residues. A special molecule selectively captures malodor molecules at contact and acts on organic aromatic and cyclic molecules like mercaptans, terpenes, amines, sulfides and ammonium. It can be used in combination with enzymes, is environmentally safe and leaves a pleasant fragrance. To apply, spray a fine mist over the whole surface exposed to undesired odors. It can be fogged on maceration ponds, lift stations, manholes, drains, sewer collector trucks, garbage containers, walls and soft surfaces, including carpets and fabrics. It can be used by metering a set amount of 8 ounces per 100 gallons of water to flowing waste sludge. 954/584-4530; www.chemtron.com.
