James river treatment plant meets odor control commitments with help from GTI covers
The James River Treatment Plant is one of nine major treatment plants operated by the Hampton Roads Sanitation District (HRSD). The James River Treatment Plant is bordered on one side by the James River, and by houses and a park on the other. Although the James River Treatment Plant had installed odor control systems to capture and treat foul air from parts of the plant, its conventional ...

Odor removal by powdered activated carbon (PAC) in low turbidity drinking water
The potential of powdered activated carbon (PAC) adsorption for odor removal in low turbidity drinking water was investigated. The batch experiments were conducted under various conditions including PAC species, dosage, contact time and dosing point. The effects of pre-chlorination and PAC dosage on turbidity were also studied. Results showed that adsorption was quite vulnerable to initial ...

Being a Good Neighbor With Eco-Friendly Odor Management
As a result of urban revitalization projects, as well as suburban sprawl and development, industrial and agricultural operations are now becoming surrounded by new residential and commercial neighbors. For industrial facilities that call these neighborhoods home, one of the biggest challenges is completely mitigating any odor that may occur. When it comes to fighting odors, being a good neighbor ...

Analysis and optimization of ammonia stripping using multi-fluid model
Ammonia recovery from anaerobic digestion (AD) is a notably beneficial process for removing excess nitrogen, producing low cost fertilizer and enhancing odor abatement. A process was developed for nutrients recovery by integrating a simple and effective stripping process with AD system. To design, optimize and scale up this system, multi-fluid model was developed to simulate flow, mass transfer ...

Case study - Meat processing odor control
Overview For its first two years of production, a food manufacturer based in South Wales, England, focused its production on potatoes. Neighborhood residents voiced no complaints about odors during this time period. However, as new production lines (including barbequed meats and curried chicken) were added, the complaints began, and it became clear that odor abatement equipment was needed to ...

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 ...

Odour Nuisance and Dispersion Modelling: An Objective Approach to a Very Subjective Problem
The three main components of a study into the behaviour of material emitted into the atmosphere, i.e. emissions, dispersion and impacts, are discussed in the context of predicting odour nuisance. In particular, the importance of the effects of buildings on dispersion, and the significance of short averaging times are considered. Finally, an approach is suggested for modelling odour nuisance ...

Flavoring & Fragrance Manufacturing Solutions for VOC and Odor Control - Case Study
Volatile Organic Compounds (VOCs) and odors are natural by-products of many chemical manufacturing processes. The manufacturing of powdered and liquid flavorings & fragrances involves production phases where VOCs and odors can escape into the ambient air. Recapture of the VOCs is important in the prevention of air pollution and smog. Smog is formed when VOCs react with nitrogen oxides (NOx) ...

Biotreatment of Odors from the Zimpro Sludge Conditioning Process
Management of odor emissions generated during thermal sludge conditioning is a well known disadvantage of the “Zimpro” process. Traditional methods of using chemical oxidation and high temperature destruction result in the formation of secondary products, such as chlorine gas, organic halocarbons or nitrogen oxides. In this study, biotrickling filter technology was evaluated at the Villa Hills ...

Nitrogen Recovery from Sewage Sludge - Case Study
Ammonium Sulphate from process air The air with which the compost from sludge processor GMB BioEnergie is aerated in the biological drying tunnels contains a lot of ammonia. The emission of this ammonia-rich air led to odor complaints in the past. Now we see this air as a source of nutrients. We pass the air through an air scrubber with sulfuric acid. This sulfuric acid binds the ammoniacal ...

A breath of fresh air - Wet scrubbing eliminates odors associated with processing discarded liquid from cheese manufacturing
When International Ingredient Corp.’s drying plant in Monroe, WI, opened in 1994, it was the first plant designed specifically for large-scale drum drying of dairy products for the feed industry. At that time, its only neighbor was a cheese producer. International Ingredient used a land spread technique to process the discarded liquids resulting from its neighbor’s cheese ...

Case study - Organic particulate filtration
Overview A food products company that mixes various types of waxes and other components to make the base for chewing gums was faced with the issue of cleaning up a slightly odorous, visible emission being exhausted from two of their process lines. The components of the emission were hot particles of chewing gum and some volatile organic compounds (VOC's). The particles would quickly clog a ...

Wet dust collection for Dry ingredients - Case study
Wax products producer achieves 99% efficiency using Tri-Mer Dust Collection Equipment. The company’s first priority was a system that would collect fugitive particulate with consistently high efficiency. Low utility cost and minimal maintenance were also important. Wet particulate collection was specified at the outset because the vapor carried with the airstream would quickly blind ...

Food Processing: Odor Control in Edible Oil Processing
Abstract: The problems with odor around a typical edible oil deodorizer are discussed in detail, and a three-step solution to eliminate these problems is presented. The three steps are a distillate recovery system which recovers most of the fatty acid in the deodorizer vapor discharge as a valuable byproduct, a closed loop barometric cooling water system which keeps the fatladen hotwell water out ...
