introduction of hydrogen peroxide by using complexing agents (DTPA, EDTA) [8, 9] or acidic wash . In addition to the alkaline hydrogen peroxide stages, transition metals perturb the oxygen stages, and magnesium sulphate is added to diminish this effect. Magnesium has beneficial properties also in the hydrogen peroxide stages . Corrosion
Waste water treatment Hydrogen peroxide is used in waste water treatment processes to remove organic impurities. It is able to remove organic contaminants such as aromatic or halogenated compounds, which are otherwise very difficult to remove. It can also oxidise sulphur based compounds that are present in the waste, thus reducing the foul odour.

stabilized hydrogen peroxide products. The product Huwa-san (a silver stabilized hydrogen peroxide) has been shown to be effective for disinfection in other systems (Toté et al., 2009), and has reportedly been used in greenhouse systems. Further studies are needed to determine critical levels required for control of certain pathogens.

Gazette's Introductory Note: The piece below is adapted from an information sheet provided by the non-profit Water Systems Council. It addresses one of the more confusing topics in water treatment, the "sulfur" or rotten egg smell in well water. Bad smelling water is variously attributed to sulfur, sulfate, or hydrogen sulfide.
Heavy metals removal in water. Heavy metals are present in ground water and are usually Nickel, Lead, Cadmium and Zinc.. These metals are present in water at ppb level under cationic form such as Zn 2+, Ni 2+, Cd 2+ and Pb 2+.. Reverse Osmosis can be performant at removing low level of heavy metals, although in aerobic conditions metal oxides can clog the membranes.
Remove heavy metals from wastewater over a wide pH range Use chemical solutions for soluble and/or particulate heavy metals, such as lead, copper, chromium, iron, manganese, mercury, nickel and zinc Remove selenium with advanced biological treatment

Hydrogen peroxide is a chemical compound with the formula H 2 O 2. In its pure form, it is a very pale blue, clear liquid, slightly more viscous than water. Hydrogen peroxide is the simplest peroxide (a compound with an oxygen–oxygen single bond). It is used as an oxidizer, bleaching agent, and antiseptic.
PURATE is a unique stabilized solution of sodium chlorate and hydrogen peroxide. The SVP-Pure™ chlorine dioxide generator uses PURATE and sulfuric acid to produce ClO2 on-site that is easily piped to the point of application. No chlorine gas is used or produced in this process.
Heavy water (deuterium oxide, 2 H 2 O, D 2 O) is a form of water that contains a larger than normal amount of the hydrogen isotope deuterium (2 H or D, also known as heavy hydrogen), rather than the common hydrogen-1 isotope (1 H or H, also called protium) that makes up most of the hydrogen in normal water. The presence of deuterium gives the water different nuclear properties, and the ...
BOD and COD Removal Hydrogen Peroxide (H2O2) ... This occurs by the natural decomposition of hydrogen peroxide to oxygen and water, i.e., hydrogen peroxide will supersaturate the wastewater with oxygen, which results in the formation of evenly dispersed microbubbles which scavenge FOG constitutents as they rise to the surface of the water ...
How does the fenton's reaction work ? H.J.H Fenton discovered in 1894 that several metals have a special oxygen transfer properties which improve the use of hydrogen peroxide.Actually, some metals have a strong catalytic power to generate highly reactive hydroxyl radicals (.OH).
Redox reactions are frequently utilized in chemical wastewater treatment and in the treatment of potable water. Oxidation processes with ozone and hydrogen peroxide efficiently remove chlorinated hydrocarbons and pesticides from potable water. In wastewater treatment, oxidation processes are used to remove difficult biodegradable compounds.
