Reducing H2S and FOG at the Discharge of a Force Main
Beginning early in 2019 our office began receiving complaints of sewer odor in the neighborhood of Fountain Ridge Section III (FR III), located in Prince George County VA. The County Operations staff investigated the wastewater collection system that serves the neighborhood, and found that odor was proliferating throughout the neighborhood. Corrosion of the sewer manholes was clearly evident. ...

How drought conditions and low flow sustainability improvements lead to increased odour and corrosion risks in sewer networks
Water conservation plays a major role in the performance and goals of water utilities and the communities they serve. Reduced consumption results in less demand on water resources, which are either consistently shrinking or have larger variability than previous years that put constraints on consistent delivery. An often-forgotten new challenge that results from conservation is a reduction in ...

How Odor Control Systems Help Eliminate Odor Emitted from Different Plants
Odor is considered one type of air pollution that does not directly affect human health but can cause stress and reduce their quality of life. The foul odors originate from various industrial sources like fish, meat, food processing plant, sewage, domestic refuse processing plants, paint, paper pulp, chemical treatment plants, oil refineries, mist collectors, livestock processing facilities, ...

I Think I Smell Sewer Gas – Home or Office – Who Can Help?
Is It Sewer Gas? The first thing to do is make sure the smell is sewer gas—usually a rotten egg smell—and not a natural gas smell, which usually smells like a skunk. If you think it’s a natural gas smell, call you’re natural gas company immediately. If it’s anything but a very faint smell, evacuate the building and wait for the gas company to give you an all clear. ...

What’s that Smell in my Office?
Have you ever gone into the office on Monday morning and noticed a strange smell that wasn’t there on Friday? What’s worse, by noon you don’t feel so good! Maybe it is a headache, or your eyes burn, or your throat is sore, or your skin itches or you just can’t concentrate on your work. The question in your mind is obvious: Is the smell connected to my symptoms and could ...

Less Obvious Health Hazards in the Workplace
Workplace exposures to agents that can cause injury to employees are generally restricted to physical, chemical or biological sources. It’s not just the factory worker who is at risk. Exposures can be presented by a variety of dusts and fibers. Renovating an office can produce gypsum dust, paint solvents, the release of asbestos fibers and hidden mold spores. A poorly running ventilation ...

Next FOG STOP - A Green Solution to Fight FOG Naturally
It caused a sensation at the Museum of London when it went on display in February. A sliver of the titanic Whitechapel fatberg, longer than three Boeing 747s, this 143-ton behemoth living underground is proof of what’s happening underfoot, everywhere — FOG a collection of fat, oil, and grease clogging our sewer systems, wreaking havoc and costing millions — but there’s a ...

Street Elbow Introduction
A street elbow is a type of plumbing or plumbing connection intended to join a piece of pipe and another corner fitting. The difference between a street bend and a regular bend is the nature of the connections at each end. A regular elbow has a female connector or FIP connection at both ends. A hub is a female receptacle made of ABS, PVC or copper; FIP refers to "Female Iron Pipe" threads, ...

Release of hydrogen sulfide under intermittent flow conditions – the potential of simulation models
For engineering purposes it is especially useful to be able to predict and control sewer corrosion rates and odor impacts as well as to design effective measures aiming to reduce effects related to hydrogen sulfide formation and release. Doing so, it is important to use modeling tools that are capable of assessing variations of dissolved oxygen, dissolved sulfide and hydrogen sulfide gas ...

Collection system aeration and the microbial benefits
In late 2015 Reliant Water Technologies introduced the Wet Well Wizard, an aeration tool for the wet wells in collection systems. During 14 months of field testing the patent pending Wizard System, the primary objectives were to eliminate FOG (fat, oil and grease) caps and to reduce H2S, eliminating it if possible. All trials were proven excellent with very few changes to the product that ...

High Rate Biological Odour Control Demonstration for Biosolids Exhausts
Abstract Biorem has successfully demonstrated its high rate odour control system for biosolids exhausts at Ashbridges Bay sewage treatment plant in Toronto, Ontario. The demonstration used XLD™, a biofiltration media engineered specifically for biosolids odours. The system has achieved 95% odour removal in less than 20-s Empty Bed Residence Time (EBRT) despite high concentration of organic ...

A review of sulfide emissions in sewer networks: overall approach and systemic modelling
The problems related to hydrogen sulfide in terms of deterioration of sewer networks, toxicity and odor nuisance have become very clear to the network stakeholders and the public. The hydraulic and (bio)chemical phenomena and parameters controlling sulfide formation, emission and their incidences in sewer networks are very complex. Recent research studies have been developed in gravity and ...

Is H2S a suitable process indicator for odour abatement performance of sewer odours?
Odour abatement units are typically designed and maintained on H2S concentrations, but operational failures are reported in terms of overall odour removal, suggesting a wide range of malodorous compounds emitted from sewers that may not be efficiently removed by existing odour abatement processes. Towards providing greater insight into this issue, several activated carbon filters and biofilters ...

Performance of sanitary sewer collection system odour control devices operating in diverse conditions
Controlling odours from sanitary sewer systems is challenging as a result of the expansive nature of these systems. Addition of oxidizing chemicals is often practiced as a mitigation strategy. One alternative is to remove odorous compounds in the gases vented from manholes using adsorptive media. In this study, odour control devices located at manholes were observed to determine the ability of ...

Municipal sewage treatment plant eliminates odors and saves money versus its previous treatment scheme
The Problem - Neighbors on the surrounding hillsides of this Northeastern Ohio sewage treatment plant were outraged by constant, intensely offensive odors from the plant's sludge drying operations. The plant's current treatment was providing only marginal success in controlling odors pouring from the exhaust scrubber. The plant was receiving hundres of calls a week. The Objective - Eliminate ...
