Comparison of BIOCUBE’s patented odor control system with in-ground biofilters
About the Project Summary: The apparent simplicity of the biofiltration process is deceptive. Various biofilter designs have been applied to wastewater odors since the 1920s, however, the acceptance of biofilters by the industry has been hampered by unreliability in the majority of designs. The BIOCUBE™ System, as patented by Biocube, Inc., is the only system to have eliminated the limits ...

Ashbridges Bay Sewage Treatment Plant, Toronto, Ontario - Case Study
ABOUT THE PROJECT 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 ...

Selection of Bioreactor Media for Odor Control
The support media is one of the most critical elements of a biofiltration system. In this chapter, biofilters and biotrickling filters will be referred to as “biofilter”, and this distinction will be discussed later in this chapter. The support media’s main function is to provide contact between the gas-phase contaminants and active microbial cultures either immobilized within and/or attached as ...

High Rate Biological Odour Control System - Case Study
About the Project Biorem has conducted a successful demonstration of high rate odour control at Preston Wastewater Treatment Plant in Cambridge, Ontario over the last three years. The system treats exhausts from primary clarifier and intermediate pump station. A combination of biotrickling filtration (BTF) and biofiltration (BF) processes was used in a novel horizontal flow configuration. XLD, a ...

Dimensioning of bioscrubber/biofilter-combinations for odour treatment at compost facilities
Composting of organic waste has been developed rapidly in Germany in the last years. While Fricke et al. (1992) counted 88 running or planned compost facilities in 1991, the number increased up to about 550 in 1998 with a total capacity of 6.5 Mio t/a of biowaste (Wiemer and Kern, 1998). So, composting is a wide spread, established process in waste management, producing an important product for ...

Evaluating odour control technologies using reliability and sustainability criteria – a case study for water treatment plants
Technologies for odour control have been widely reviewed and their optimal range of application and performance has been clearly established. Selection criteria, mainly driven by process economics, are usually based on the air flow volume, the inlet concentrations and the required removal efficiency. However, these criteria are shifting with social and environmental issues becoming as important ...

Manic 5 and Manic 5 PA (Hydro Québec), Quebec case study
Part of an hydroelectric complex counting four dams, Manic 5 and Manis 5 PA are two power houses installed in the valley of the Manicouagan river, north of Québec. Unveiled in 1970, this plant represents the higher multiple-arch and buttress dam in the world. For the Manic 5 and Manic 5 PA sanitary water treatment, Hydro-Québec mandated the Groupe-conseil TDA to find a compact ...

Odour control on waste water treatment plants and pumping stations using DMT biotrickling filtration
Lengthy detention times and warm weather / climate leads to septic waste water producing copious amounts of not only hydrogen sulphide, but also ammonia, organic sulphides, mercaptans, bringing numerous odour complaints on waste water treatment plants ( WWTP’s ) and pumping stations. An odour abatement unit therefore will have to treat not only hydrogen sulphide, but also other pollutants ...

Growing water shortages, air & water pollution challenge US to take a sustainable approach to the environment
With 36 states expected to experience moderate to extreme water shortages by the year 2013, the time has come for the United States to rethink its approach to the treatment, storage and reuse of water on a residential, industrial, and municipal level, according to Bord na Móna Environmental Products U.S. Inc. President Shane Keaney. “The aging United States water treatment infrastructure now ...

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 ...

WWTPs, how to prevent and control the generation of odorous gases
There are three commonly used technologies for the prevention and control of odor gases: 1: chemical scrubbing The chemical scrubbing treatment system consists of passing the gas through scrubbing towers where air/water/reagent contact takes place. In chemical scrubbing, an acidic or basic chemical solution is injected into the system from the top, passing through the flow of the gas, and is ...
