Odour Management for Organic Waste Facilities

Odour Management for Organic Waste Facilities

Going beyond the theoretical, this one-day workshop will delve into odour management for each phase of organic residual processors from planning to operation (composting, anaerobic digestion, landfill and transfer stations). Presented by senior odour expert with over 20 years of practice in the assessment, measurement and prevention of odours

Community Odor Monitoring

Community Odor Monitoring

The objectives of Community Odor Monitoring Projects are to involve the community in assessing odor impacts, determine the odor impacts on nearby residents and provide feedback to operators, stakeholders and community members. A well-executed Community Odor Monitoring Projects helps identify sources of odor pollution and assess the performance of implemented solutions. It also improved factual information and enable proactive response of plant operator to the neighbors’ concerns.

Odor Monitoring for Composting Order of Approval

Odor Monitoring for Composting Order of Approval

Lenz Enterprises has an Order of Approval from the Puget Sound Clean Air Agency. This approval required installation of an odor monitoring system that measures and reports results in odor units (OU)/cubic meter. Lenz installed an Odotech monitoring system, which has electronic noses (e-noses) positioned near the odor sources — one located on the back wall of the ASP zones and the other on the northwest corner of the organics receiving building. Sensor data is automatically logged by the Odotech system and Lenz uses this information to develop reports for the agency.

How to Measure Odor

How to Measure Odor

Odors are normally quantified by dynamic dilution olfactometric analysis. Olfactometric analysis consists of determining the olfactory perception threshold of a gaseous sample. The olfactory perception threshold is defined as the number of dilutions at which 50% of a jury perceives the odor while 50% do not. This does not involve the determination of the quality of the odor. By definition, the olfactory perception threshold is equivalent to 1 odor unit per cubic meter of air: “1 o.u./m3”. The number of dilutions of the odor sample required to obtain 1 o.u./m3 indicates the odor concentration of the sample in odor units per cubic meter of air [o.u./m3].

How to communicate your odor mitigation plan

How to communicate your odor mitigation plan

In the context of odor management, communication is of special importance and should not be set aside. Exposure to offensive odors raise questions about potential health risks, loss of property value and the fear of additional odor episodes. They can become a source of stress, frustration and anger, especially when the neighbors do not feel that their situation is taken care seriously. The lack of communication can increase irritation and cause a loss of trust in those responsible (plant operators, policy makers and officials). To communicate your efforts to reduce odors, your mitigation objectives, the budgets invested and results achieved can help to reduce the feeling of injustice and powerlessness that some residents may develop. Too often in tense situations, some facility operators fail to communicate their plan of action and positive outcomes obtained. Although significant improvements have been achieved in terms of reducing the level of odors and frequency of exposure, the discontent in the community has not necessarily diminished because a lack of communication and trust. Proactive communication through an odor observer committee (OOC) is an excellent way to promote the emergence of communication between the managers of the odor emitting sites and nearby residents. In the process of setting up an OOC, a group of volunteers from the community are trained to recognize and quantify odors and how to report odors in a consistent manner.  The OOC provides an effective communication channel between members of the community and the plant managers. This helps to convey odor mitigation plan objectives and odor observations relevant for environmental monitoring and management operations. On a regular basis, members of the...

First in Class Odor Monitoring in California @ CWEA Annual Conference

Orange County recently became the largest installation of OdoWatch – Electronic Nose and live plume Odor Monitoring – system in California.  They are currently monitoring their Plant 2 at Huntington Beach, and will be monitoring Plant 1 in the near future. We invite you to learn more on this project at the California Water Environmental Association annual conference & show show in Santa Clara this week May 1-3. Here is the link to the annual conference website for CWEA:http://www.cwea.org/et_attendees_conferences.shtml Kruger, the exclusive U.S. distributor for OdoWatch to municipal wastewater treatment facilities in the United States, is at the CWEA show in Santa Clara (Booth #407).  Stop by the Kruger booth to see what makes the Orange County system unique.  OdoWatch systems are used by any size WWTPs in order to understand their odor impact, be proactive, and find rational odor reduction solutions at the lowest operational and capital cost.  See how OdoWatch can save you money through using your capital and staff to their best possible...
