EQuIS Collect to EnviroInsite
Environmental remediation and compliance monitoring are time sensitive and dependent on quick access to reliable, actionable information. Data visualization is often the most appropriate means of decision support for day-to-day monitoring and site characterization. However, the time delay between data collection and data visualization is not conducive to time critical decision making. Legacy ...

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 ...

MSW Management: Safely Countering the Rise of Landfill Odors
One of the core challenges of landfill and compost site management is fighting the rise of foul odors. In addition, as communities expand further out from previous areas, they eventually become neighbors to landfills – calling for a comprehensive odor-control approach to countering odor complaints. In fact, compared to other industrial applications such as wastewater treatment and asphalt ...

Comparison of different measurement methods of odour and odorants used in the odour impact assessment of wastewater treatment plants in Poland
The aim of this study was to compare sensory and analytical methods used to measure odour and odorants concentrations for odour impact assessment on municipal wastewater treatment plants (WWTPs). A range of sources and odour or odorants concentrations were used to compare the methods. Four different odours and odorants measurement methods were compared: field olfactometry using Nasal Ranger® ...

Release behavior of odor contaminants derived from Microcystis aeruginosa in rivers and a non-strict anaerobic aqueous system
Data were collected and reviewed to assess the odorous contaminant status of drinking water sources for Hangzhou City, China. β-Cyclocitral, β-ionone, dimethyl trisulfide, 2-methylisoborneol, and geosmin were targeted odorants. Results indicate that β-cyclocitral was the main contaminant in source waters as it was most frequently detected and occurred at higher concentrations compared to ...

Odour reduction strategies for biosolids produced from a Western Australian wastewater treatment plant: results from Phase I laboratory trials
This study investigated sources of odours from biosolids produced from a Western Australian wastewater treatment plant and examined possible strategies for odour reduction, specifically chemical additions and reduction of centrifuge speed on a laboratory scale. To identify the odorous compounds and assess the effectiveness of the odour reduction measures trialled in this study, headspace ...

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 ...

Aerating recycled water on mushroom composting sites affects its chemical analysis and the characteristics of odor emissions
Recycled water (RW) containing compost leachate can be a potent source of foul odor on mushroom composting sites. Samples of RW were repeatedly collected from storage tanks and pits of 14 mushroom composting sites in England and Ireland. Relationships between the effects of submerged aeration of the RW, the chemical and microbial characteristics of the RW, and the odors emitted were investigated. ...

Assessment of lagoon odor emissions before and after installation of solar-powered circulators; Myrtle Beach water reclamation facility
Introduction The City of Myrtle Beach operates a large wastewater treatment lagoon in parallel to its mechanical treatment plant located off Mr. Joe White Avenue in Myrtle Beach, South Carolina. The lagoon system occupies an area of over 45 acres. The large, odor-emitting surface area, combined with encroaching development, has resulted in complaints against the City regarding odor emissions from ...
