TOTALOX Odor Eliminator: The Two Step Treatment in One Package - Case Study
Collection Systems Are Tough! With miles of pipe and multiple pumping stations, managing the complexity of a wastewater collection system is a full time job. The main task is to maintain the system and keep it flowing. But also near the top of that task list is preventing nuisance odors. When the phone starts ringing, you become a detective. First, you have to find the site or sites of odor ...

Toxic and Combustible Gasses – Safety is Paramount
On January 31, 2022, a fire at a North Carolina fertilizer manufacturing facility caused officials to urge residents living nearby to stay away from their homes due to an increased risk of a possible explosion at the facility. People with respiratory issues were likewise advised to take precautions to minimize their potential exposure to toxic gasses. According to Winston-Salem fire chief ...

Ozone as a Disinfecting Agent in The Reuse Of Wastewater
More and more countries are taking measures to reuse wastewater. This has been prompted by the ever decreasing availability of good quality raw water and the increasing cost of producing potable water. Disinfection is a major treatment step in the direct reuse of reclaimed wastewater to ensure environmental and public health protection. “Disinfection is the destruction, inactivation or removal ...

Development of a diagnostic tool: the wastewater collection network odour wheel
The assessment of nuisance odour problems and the application of an effective odour management programme for the associated industrial activity may be achieved using a representative odour wheel and Odour Profile Analysis methodology. The odour wheel is a very useful tool for conducting odour quality control monitoring and developing a constructive dialogue regarding nuisance odours with the ...

How to use Geomembranes in an Animal Waste Lagoon Pond Liner?
The principle of deodorizing the sewage pool is based on the composition of the odor, using acid, alkali, and strong oxidant as the washing spray solution to react with the odor molecules in the gas, and then remove the odorous ...

Kinetics of aerobic oxidation of volatile sulfur compounds in wastewater and biofilm from sewers
Laboratory experiments were conducted to investigate the kinetics of aerobic chemical and biological oxidation of selected odorous volatile sulfur compounds (VSCs) by wastewater and biofilm from sewers. The VSCs included methyl mercaptan (MeSH), ethyl mercaptan (EtSH), dimethyl sulfide (DMS) and total inorganic sulfide, which have all been reported as the main constituents of foul sewer gas. ...

Waste Gas in Metal Recycling: Hydrocarbons and carbon monoxide - Case Study
Example: Aluminium recycling Similar tasks: Recycling of copper, lead, cink The waste gas in metal recycling usually contains particles (abraded metal, mineral dust), inorganic, acid substances (HF, HCI, SOx) and dioxins (PCDD/F) as well as a whole range of organic substances (unburned hydrocarbons) and carbon monoxide. Particularly, in the group of unburned hydrocarbons some substances such as ...

Bakery Emission & Odor Control
While working with local regulators to satisfy air pollution control requirements for two new oven lines, bakery engineers explored the utilization of waste heat from pollution control systems. Like many other industries, food processors often find that the best available control technologies for emission and odor abatement are thermal and catalytic oxidizers. This bakery was particularly focused ...

The use of potassium permanganate, ozone and associated coupled processes for odor removal in drinking water: bench and pilot scale tests
Bench and pilot scale experiments were conducted to investigate and compare the preoxidation effects of potassium permanganate (KMnO4) and ozone (O3) for odor removal in drinking water. The effects of dosage, contact time, pH, as well as couple treatment with a granular activated carbon (GAC) filter were examined using bench experiments, while the effects of KMnO4 dosing points and a ...

Reduction of chlorinous odor by the combination of oxidation and ion-exchange treatments
To better control chlorinous odor in tap water, we assessed the performance of the combination of oxidation (ozonation or advanced oxidation processes, AOP) and ion-exchange treatment. In this process, the hydrophilic neutral fraction (a major dissolved organic matter (DOM) fraction) is converted to ionic species, and these ions and ammonium ion are effectively removed during ion-exchange ...

Application of Biotrickling Filter for Odor Control at The Morris Forman Wastewater Treatment Plant
Pilot-scale study of a biotrickling filter using synthetic, high surface area media was undertaken by MSD Louisville, with the intention of saving the high cost of operating thermal oxidizers. Currently, two recuperative thermal oxidizers are used to treat odorous emissions from various sources. The pilot study showed that it is possible to treat hydrogen sulfide and organic sulfur compounds at ...
