During the last two decades, much research work has been published regarding the use of metallic iron (Fe 0) for the treatment of hexavalent chromium (Cr VI) contaminated waters. Chromium may enter the aquatic ecosystems through the discharge of contaminated wastewaters from steelworks, metal finishing chromium electroplating, preservation of wood leather tanning, corrosion control, dyeing of textiles, manufacture of ceramics, catalysts, and pigments, etc. Due to their bioaccumulative and non-biodegradable properties, heavy metals can produce cumulative deleterious effects even in low concentrations in a wide variety of aquatic organisms. Heavy metal pollution has become a major area of concern because of high concentrations released into the environment. The present work critically reviews existing knowledge on the Fe 0/Cr VI/H 2O and Cr VI/H 2O systems, and clearly demonstrates that direct reduction with Fe 0 followed by precipitation is not acceptable, under environmental relevant conditions, as the sole/main mechanism of Cr VI removal in the presence of Fe 0. Moreover, recent investigations recalling that a Fe 0/H 2O system is an ion-selective one in which electrostatic interactions are of primordial importance is generally overlooked. An overview on the literature on the Cr geochemistry suggests that the reductive-precipitation theory should never have been adopted. This view is still the dominant removal mechanism (reductive-precipitation mechanism) within the Fe 0 remediation industry. The introduction of the Fe 0-based filtration technology, at the beginning of 1990s, was coupled with the broad consensus that direct reduction of Cr VI by Fe 0 was followed by co-precipitation of resulted cations (Cr III, Fe III). Despite a great deal of research, the mechanisms behind the efficient aqueous Cr VI removal in the presence of Fe 0 (Fe 0/H 2O systems) remain deeply controversial. In recent years, attention has been focused on the use of metallic iron (Fe 0) for the abatement of Cr VI polluted waters. Another major issue of concern about Cr VI compounds is their high mobility, which easily leads to contamination of surface waters, soil, and ground waters. Cr VI is highly toxic to most living organisms and a known human carcinogen by inhalation route of exposure. Treating 5ppm Hydrogen Sulfide and killing SRB, and slime bacteria.Hexavalent chromium (Cr VI) compounds are used in a variety of industrial applications and, as a result, large quantities of Cr VI have been released into the environment due to inadequate precautionary measures or accidental releases. “Water smells clean and tastes great!” Midlothian, VA. The Sulfur Eliminator System carries a limited lifetime warranty and a 100% money back guarantee. No Chemical Solutions To Mix– No Dangerous Chemicals To Handle.ĭoes not require any chlorination treatments. The Sulfur Eliminator is the lowest maintenance and only 100% effective sulfur treatment system that will Eliminate SRB and hydrogen sulfide, “Rotten Egg Smell” instantly and permanently.įiberglass Treatment Tank and Molded High Strength Plastic Control Valve. The McCoy Sulfur Eliminator system exceeds the performance of the Sul-X and is safe and all natural.įrom the same trusted inventor family that brought you the MacClean Chem Free Iron Removal System and the MacClean Sul-X System. McLean, invented and patented the MacClean Sul-X System. The system kills menace bacteria as it flows in form the source and kills all bacteria throughout the plumbing system safely without adding any chemicals to the water.īrian McCoy’s grandfather, Dr. It would take a continuous chlorine treatment just to mask the smell.īrian McCoy has invented a treatment that instantly kills sulfate reducing bacteria as well as completely oxidizing hydrogen sulfide. The colony becomes more and more resistant to any further chlorination treatments. Chlorination may kill a few in a colony, but all others quickly adapt and evolve to pass on more resistant genes. SRB is a menace that lives inside plumbing feeding on minerals in water and creating hydrogen sulfide or rotten egg smell.īrian proved chlorination will not kill this bacteria. Sulfate Reducing Bacteria or SRB is a single cellular organism that lives deep inside the earth and invades potable water sources. This IS THE ONE AND ONLY Sulfur Eliminator,īrian McCoy discovered the underlying cause of sulfur smell in water.
