Hydrogen sulfide gas emission under turbulent conditions – an experimental approach for free-fall drops
Odor nuisance and sulfide corrosion in sewers carrying septic wastewater are accelerated at points of turbulence such as drops in manholes, but accurate methods or empirical expressions to evaluate the gas stripping rate at those particular sites are still missing. With the aim of improving the current knowledge on the influence of free-fall drops on the release of hydrogen sulfide gas, an ...

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 ...

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 ...

Comparison of two standard odor intensity evaluation methods for odor problems in air or water
Government agencies responsible for ensuring healthful water and/or air quality are often faced with resolving public complaints of nuisance odors. Understanding variations in odor intensity may ultimately lead to the establishment and application by such agencies of quantitative limits for effective odorant control. An odor panel was trained in suprathreshold odor intensity evaluation using ...

Case study - Controlling odors at a specialty plastics manufacturer
Challenge A specialty plastics manufacturer in the eastern United States makes a plastic compound that, because of its unique and desirable properties, is widely used in the automotive industry. Complications arose for this manufacturer because, in the production process, mercaptans are driven off and produce a non-hazardous but offensive nuisance odor problem. The manufacturer's neighbors were ...

Landfill eliminates nuisance odors, saves a large revenue stream and increases profits
The Problem - Neighbors surrounding a southwestern Ohio landfill were outraged by the offensive odors emanating from the site's sludge processing operations. The neighbors complained to local and state regulators every time a load of the offending material was delivered for processing. The site had to do something otherwise they were going to lose the lucrative sludge disposal contract. The ...

New home with Puraflow septic system and odor complaint - Case Study
Problem After installation of a Puraflow septic system the customer complained of odors in his yard. The contractor installed residential vent odor filters on the tank vent on the roof vents. The residential odor filters improved but did not eliminate the problem. The contractor reviewed the problem with Simple Solutions and determined that the problem was due to the airflow from the tank vent ...

Control of odour nuisance in urban areas: the efficiency and social acceptance of the application of masking agents
This paper presents and discusses the results of the project named ‘Jasmin’ implemented in Algiers to control the strong odours of the river named Oued El Harrach, one of the largest rivers in the centre of the city. Pending the achievement of curative solutions, a temporary option for mitigation of nuisance odour by masking agents was implemented in the vicinity of the main ...

Lift Station Odor Control Using CARUSOL Treating a Wastewater Collection System in a Mid-Western Township - Case Study
Summary A mid-western township is responsible for operating and maintaining a combined sewer collection system consisting of 150 miles of pipeline and 28 pumping stations. The township does not treat the wastewater, instead contracting with a neighboring city for this service. The township has two final lift stations that transfer the collected wastewater to the neighboring system for ...

Five reasons cities should take a leading role on food waste
Reported figures from the Food and Agriculture Organization of the United Nations (FAO) on food loss and food waste highlight its importance to the global environment. Food loss and waste annually contribute 3.3 gigagrams of CO2 equivalent, or over twice the total emissions of India; waste 250 cubic kilometers of water which is equivalent to 100 million Olympic-sized swimming pools; and 1.4 ...

Case Study: Odor Abatement Solutions
Odor issues related to industrial processes are not uncommon. An odor is caused by one or more volatilized organic compounds (VOCs) that humans can perceive by the sense of smell. The challenge is that “odor is subjective, and what is sweet to some, can be a nuisance to others. In most cases the compounds that create the offensive odors are not present in sufficient concentrations to ...

Case study of odor and indoor air quality assessment in the dewatering building at the Stickney Water Reclamation Plant
Indoor air quality (IAQ) and odors were determined using sampling/monitoring, measurement, and modeling methods in a large dewatering building at a very large water reclamation plant. The ultimate goal was to determine control strategies to reduce the sensory impacts on the workforce and achieve odor reduction within the building. Study approaches included: (1) investigation of air mixing by ...

A comparison of an organic biofilter and an inorganic biofilter for the treatment of residual odors emanating from a biosolids de-watering facility
ABSTRACT: The following paper is a comparison of an organic media biofilter and a synthetic media biofilter for the treatment of residual odors emanating from the operation of a biosolids dewatering and truck loading system at the City of Toronto's Ashbridges Bay Treatment Plant. The system compared was an in-ground, header/lateral system operated in a forced draft, up flow, open top ...

Odour Nuisance - Where We Are and Where to Next?
Prior to 1990 there were very few examples of effective odour control schemes at sewage treatment works. Sources were often not properly identified, much less quantified and budgets did not allow the introduction of properly engineered solutions. Since then, in response to a seemingly endless increase in pressure from public, considerable progress has been made tackling the problem. First ...

Odours in sewer networks: nuisance assessment
As odour nuisance can affect the quality of life, the population is more and more demanding and in many cities sewers are a critical source of odours. Both factors can lead to increasing numbers of complaints due to the odour nuisance perceived by the residents, affecting also the public image of the sewer management companies. Odours associated with sewer networks are very heterogeneous, in as ...

10 tips for journalists covering biosolids
For 20 years, I've worked with reporters and journalists on their coverage of biosolids and related topics. I'm speaking here of professionals who write fact-based news or feature articles, not those who write opinion-based pieces or columns that reflect and include their personal bias and/or advocacy. What these reporters and journalists do is important, serving as conduits of useful ...
