GO2: Chlorine Dioxide for Wastewater Treatment

GO2 is effective as both a disinfectant and an oxidant in wastewater treatment. GO2 has several distinct chemical advantages compared to the traditional use of chlorine in wastewater treatment. GO2 does not significantly hydrolyze in water, thus it retains biocidal activity over a broad pH range.

GO2 is non-reactive with ammonia and most nitrogen-containing compounds, and thus is effective at lower dose levels than chlorine. It destroys phenols, simple cyanides and sulfides by oxidation.

For odor control, GO2 will oxidize sulfides without the formation of colloidal sulfur. It is also used to oxidize iron and manganese compounds.

GO2: Chlorine Dioxide for Municipal Water

GO2 (CLO2) is 10-times more powerful in its disinfection strength than standard Chlorine. GO2 addresses specific disinfection tasks that Chlorine cannot accomplish and has a far longer effective life. In addition, to purifying drinking water, GO2 also removes biofilm in water pipes, tanks and distribution systems. Chlorine does not address this important issue.

Unlike Chlorine, GO2 has no known negative side effects. 1 ppm GO2 delivers the same disinfecting power as 10 ppm Chlorine. The dilution factor plays an important role in safety and cost comparison. Additionally, GO2 is harmless, whereas Chlorine is dangerous to use and has harmful side effects on human, animal, plant and marine health.  GO2 is US NSF-60 approved.

GO2: Chlorine Dioxide Key Features

♦  Eliminates microbial slime and prevent its reformation in drinking water and process water systems
♦  Reduces equipment needs and maintenance costs
♦  Improves water quality
♦  2 simple powers mixed in tap water produces pure CIO2 at 95% efficiency of conversions
♦  Environmentally safe chemistry
♦  Easy, safe and effective to use, store and transport
♦  Very Competitive use cost when compared to traditional treatments
♦  GO2 eliminates the need for a conventional ClO2 Generator (approximately US $10,000)
♦  Does not react to water to form hypochlorous acid. No “free chlorine”
♦  No harmful By Products. Environmentally friendly
♦  Unlike chlorine, GO2 does not react with ammonia, ammonium or other organic compounds
♦  Non corrosive to systems, pipes, pumps, filters, equipment

Biofilm:  In existing water distribution systems, the distribution pipes are permanently contaminated with biofilm. The biofilm consists of two layers. There is a hard layer compacted against the inner wall of the distribution pipe. Within the hard layer is a soft biofilm layer. The soft layer deposits flakes of biofilm into the water current. The biofilm deposits block piping systems, drinking water nozzles and cleaning sprays, etc. Chlorine does not eliminate, or even inhibit, the growth of biofilm.

Tests with GO2 showed that the inner thin layer of the biofilm was 100% removed after 7 days. The hard layer requires 60 to 120 days to remove, depending on the thickness of accumulation. In all cases the hard layer is completely removed. The process of decontamination is completely safe and has no adverse side effects.

Disinfection Control in Oil Wells and Petroleum Systems

GO2 is effective in the remediation of bacterial and sulfide contamination commonly found in oil field production, injection and disposal fluids. Sulfides are formed by the metabolism of anaerobic sulfate reducing bacteria found in oil well water handling systems. These sulfides react with iron to form insoluble iron sulfide, which together with the bacterial slime act as plugging agents. The sulfides can also result in sour crude oil which is of lower quality and more expensive to refine.

Application Areas

GO2 is used for two purposes in this application:

1. As a chemical oxidant to oxidize the sulfides to sulfates, thus preventing the formation of colloidal sulfur or iron sulfide which can plug the well

2. As a biocide to kill the bacteria which produces the sulfides. Performance of GO2 is unaffected by pH or by the presence of other organic materials.

GO2: Chlorine Dioxide for Soil Remediation

Soil remediation using GO2 chlorine dioxide generated onsite can be used to oxidize organically contaminated aqueous waste streams, in addition to simple and complex cyanide in water, soil, or sludge.

Chlorine dioxide is an ideal oxidizing agent because it chemically alters contaminants to salts and non-toxic organic acids. This is applicable to aqueous wastes, soils, or any solid application contaminated with organic compounds. This includes applications to soil and ground water contaminated with pesticides or cyanide, sludges containing cyanide,  pentachlorophenol, or other organics, and industrial waste water similar to refinery wastewater.

Since chlorine dioxide reacts via direct oxidation, the process does not form undesirable trihalomethanes (such as what chlorine bleach forms).
