So formed, chlorine dioxide may undergo many chemical or electrochemical reactions. With organic matter it again forms chlorite. If ozone is generated, it reacts in the ms-range with chlorine dioxide in competition with the reaction with active chlorine (Gordon et al. 2002) ... [Pg.181]

The use of electrochemically generated oxidants for the indirect oxidation of organic wastes has an inherent advantage in that direct electrochemical oxidation of the wastes can occur simultaneously. However, the use of chlorine and hypochlorite has raised concern because of the formation of chlorinated organics. Fortunately, ecologically desirable oxidants such as ozone and hydrogen peroxide (which decom-... [Pg.381]

Indirect oxidation, whereby electrochemically generated oxidants, such as ozone, hydrogen peroxide, hypochlorite, Fenton s reagent, or peroxodisulfate are applied for oxidation [16,17]. [Pg.1072]

There are several waste water treatment applications which involve electrochemically generated oxidants. Suitable oxidants include ozone, hydrogen peroxide and notably hypochlorite, which is widely used. [Pg.394]

A number of electrochemically generated oxidants may be used to purify water streams. In Chapter 3, cells for hydrogen peroxide (section 5,7) and ozone (section 5,8) generation were described in some detail The most traditional oxidizing agent in these circumstances, however, is undoubtedly hypochlorite or chlorine.

Anodic processes may occur by direct electrochemical reaction of the waste at the anode, or by indirect oxidation when an oxidizing agent is generated in the waste stream. For example, oxygen and ozone may be generated from water in the waste stream, or the addition of sodium chloride to the waste stream can be used to generate free chlorine or hypochlorite at the anode. In addition, metal ions of higher valence states can be produced at the anode to oxidize wastes. [Pg.372]
