The presence of hydrogen sulfide in home drinking water supplies is not a health hazard, but is a common nuisance contaminant whose distinctive “rotten egg” odor makes water treatment desirable. Several treatment methods are available, and often hydrogen sulfide can be treated and removed using the same process and equipment used for iron and manganese removal.
Sulfates and hydrogen sulfide are both common nuisance contaminants. Although neither is usually a significant health hazard, sulfates can have a temporary laxative effect on humans and young livestock. Sulfates also may clog plumbing and stain clothing. Hydrogen sulfide produces an offensive `rotten egg` odor and taste in the water, especially when the water is heated.
Oxidation Reduction Potential or Redox is the activity or strength of oxidizers and reducers in relation to their concentration. Oxidizers accept electrons, reducers lose electrons. Examples of oxidizers are: chlorine, hydrogen peroxide, bromine, ozone, and chlorine dioxide. Examples of reducers are sodium sulfite, sodium bisulfate and hydrogen sulfide. Like acidity and alkalinity, the increase of one is at the expense of the other.
Control nuisance odors with accurate monitoring. In wastewater treatment, nuisance odors can end up being much more than just a nuisance. Complaints about hydrogen sulfide odors can lead to citations, penalties or worse. Don’t wait for your neighbors to let you know that you have an odor problem; keep on top of hydrogen sulfide odors with a Jerome hydrogen sulfide monitoring solution.

Hydrogen sulfide is the chemical compound with the formula H2S. H2S is colorless, toxic and flammable and is responsible for the foul odour of rotten eggs and flatulence. Hydrogen sulfide often results from sulfur reducing bacteria in nonorganic matter (in the absence of oxygen), such as in swamps and sewers (anaerobic digestion). H2S also occurs in volcanic gases, natural gas and some well waters.
You know that measuring hydrogen sulfide in the air only shows you the tip of the iceberg when it comes to identifying H2S odor from wastewater. But did you also know that it is possible to continuously measure the levels of dissolved hydrogen sulfide directly in wastewater instead? It is!
The BevAlert Model 8900 provides a total sulfur measurement for sulfur compounds in Carbon Dioxide. The measurement includes organic sulfides, Sulfur Dioxide, Carbonyl Sulfide, and Hydrogen Sulfide. The instrument is utilized by Specialty Gas Manufacturers and the Food and Beverage Industry to monitor sulfur compounds in CO2 used in carbonated beverages.
Total reduced sulfur(s), which include hydrogen sulfide (H2S), methyl mercaptan (methanethiol, CH3SH), dimethyl sulfide (CH3SCH3), and dimethyl disulfide (CH3S2CH3), occur naturally in the environment and can also be present in numerous industrial gaseous streams – petroleum refining, natural gas extraction, and chemical operations like the pulp/paper industry. Hydrogen sulfide is the most prevalent of the total reduced sulfurs, and is commonly found in volcanic gases, marshes and swamps, wetlands and mud flats,...
In the treatment of sanitary sewage, bio-solids are separated from the liquid. These bio-solids are concentrated and dewatered using filter presses, centrifuges, or other devices. Hydrogen sulfide and mercaptans are released during the dewatering operation. Carus permanganates react quickly and produce immediate results for hydrogen sulfide removal in order to provide a safe, odor free environment and minimize corrosion due to sulfides.
Aeration is an effective and low-cost solution to oxidize iron and manganese. It can also provide high-efficiency removal of gases such as hydrogen sulfide, carbon dioxide, methane, and volatile organic carbons, which results in better process performance and/or improvement of taste and odor.
Trusted odor detection at parts-per-billion (ppb) levels. If you operate a landfill, you know that it takes constant vigilance to keep your community happy. Monitoring for hydrogen sulfide odor is no exception. When planning your strategy for hydrogen sulfide odor control, be proactive. Be prepared. Trust Jerome to give you the data you need to make the right decisions.
Sulfur compounds, such as hydrogen sulfide, thiosulfates and mercaptans, can present serious refinery wastewater problems. Hydrogen peroxide treatment is a cost effective way to treat these reduced sulfur species.
The largest volume effluents in petroleum refining include “sour” process water and non-oily/non-sour but highly alkaline process water. Sour water is generated through a number of processes, such as:
- Vacuum distillation
- Middle distillate hydrodesulphurization
- Catalytic cracking
- Visbreaking/thermal cracking
Sour water may be contaminated with hydrocarbons, hydrogen sulfide, ammonia, organic sulfur compounds, organic acids, and phenol....
H2S/Total Sulfur analyzers for Natural Gas pipeline integrity monitoring. During the extraction and processing of raw Natural Gas, midstream companies are required to track the level of Hydrogen sulfide (H2S) and Total Sulfur (TS). Accurate analysis of H2S in Natural Gas is of high importance to reach natural gas standard and to avoid equipment corrosion, as well as the decrease of heating values.
The Clean Air Group, LLC has provided many scrubbers (venturi type, ejector type, packed towers) for the chemical plant area of refineries. These have treated pollutants such as elemental sulfur, maleic anhydride, pthalic anhydride, ethylene oxide, hydrogen sulfide, etc. Our venturi scrubbers can be effectively utilized to handle the off-gases from FCCUs. Other specialized applications (for instance using Stretford Solution in an Ejector scrubber for high efficiency H2S removal) are not unusual for Clean Air...
Hydrogen Sulfide is lethal if released. Macrotek is a leader in developing advanced technologies for optimum removal and treatment. Our experience includes many installations using caustic, oxidizing reagents, catalytic and forced oxidation combination, and biofilters. Each application is unique and requires custom solutions.
The Series 8900 Hydrogen Sulfide and Carbon Disulfide Analyzer provides direct measurement of H2S and CS2 in ambient air. This instrument is utilized for continuous emission monitoring. The Series 8900 H2S and CS2 Analyzer employs a Photoionization detector (PID) as the sensing element. A dual column configuration with timed backflush to vent is used to strip off moisture and heavier hydrocarbons. A pre-cut column is used in series with the analytical column.
