A paper written by two of corrosion control water treatment company, Anue Water’s own executives has recently been published. It appears in Chemicals Knowledge Hub and World Water magazine. In this paper, they discuss how ozone and oxygen treatment can replace chemical deliveries and labor, saving time and money for wastewater treatment facilities. Here is an excerpt from the published article.
Corrosion Control Water Treatment Caused by H2S
A major contributor to odor and corrosion control water treatment in industrial systems is hydrogen sulfide (H2S) and its associated compounds. Some industrial wastewater contains sulfur compounds, which provide the molecular basis for the generation of H2S. H2S arises from the combination of anaerobic conditions and the presence of sulfites and sulfates in conjunction with colonies of microorganisms present on the inner walls of all collection systems, referred to as the slime layer. Sulfate reducing bacteria (SRB) will use these compounds in the absence of free oxygen (O2) for metabolism. These bacteria do not use the sulfur component, and it is available to react with water, specifically free protons (H+), which results in the generation of H2S.
Corrosion and Oxygen Ozone Water Control
Following its generation, H2S can be released into the atmosphere and find its way to receptors through junctions of the atmosphere and collection system, at which point it is an odor concern. H2S is a colourless gas that has a characteristic ‘rotten egg’ odor, is highly toxic and is corrosive to certain metals. It is heavier than air, meaning it can accumulate in wells, manholes and other locations that do not have much ventilation.
H2S becomes a corrosion issue when it contacts moist concrete or steel (among other metals) in the presence of oxygen, even at very low gaseous concentrations. Conditions such as these are common in the headspace of some pipes and other areas where the collection system has easy access to atmospheric oxygen. Bacteria in these areas convert the H2S into sulfuric acid, which then begins a destructive reaction with the infrastructure.
Historically, control of odor and/or corrosion has been implemented through either vapour phase techniques, where the headspace of a system is treated, or liquid phase techniques, where treatments target the liquid flow. Vapour phase treatments like scrubbers do not provide corrosion control. Some of the liquid phase techniques offer corrosion control.
The most common method of inducing liquid phase treatment, or directly treating the wastewater inside collection systems with oxygen ozone water control, has been by dosing chemicals into the systems. These chemicals are meant to react with the odor-causing compounds present in the wastewater, or cease their formation and/or release.
