Ideal for restroom, food service, industrial and transportation. Sewer D is ideal for deodorizing all types of wastewater and sewage treatment plants.

Sewer D will not kill algae, aerobic or anaerobic bacteria, and is nonflammable and nontoxic. Climatic conditions do not affect Sewer D and works well in a wet or dry environment. Sewer D is an effective odor counteractant because it facilitates the interaction and oxidizes the odor causing compounds to a higher oxidation state. These compounds in the higher oxidation state do not cause odors. Odors come from essentially two sources: the decay of organic matter such as waste products from plants or animals and from the interaction of minerals with ground acids or even water. In all cases, the conditions which give rise to odors are organic or inorganic compounds in low oxidation states. Almost without exception, those compounds with disagreeable odors are sulfides, mercaptans, amines and other organic materials in their lowest oxidation state. Attempts to control odors are generally by three methods. One is to dull or numb the olfactory nerves so that a person cannot smell at all. Another involves masking one odor with another such as perfume. The third method, the one employed by Sewer D, is to oxidize the odor causing compounds.
