Odor Control
Unpleasant odors can cause a lot of problems in industrial settings. These odors can cause discomfort and health issues for employees, as well as for people living in nearby communities. They can also lead to a decline in productivity, increased absenteeism, and damage to a company’s reputation.
Lonaz is here to help you To prevent these issues, it’s important for industrial facilities to implement effective odor control measures. These measures can include everything from improving ventilation systems to using specialized odor control products.
A number of treatment technologies are in use or have been used to manage odours in both collection systems and wastewater treatment plants. These include wet chemical scrubbers, adsorption using activated carbon or activated alumina, thermal destruction and more recently biotechnology. Packed-bed wet chemical scrubber systems have been the most common form of odour control in use at WWTPs. In a packed-bed wet scrubber, odorous gases pass upward through the scrubber and are removed by the scrubbing solution as it moves downward over the packed-bed. A scrubber is typically designed to remove one type or class of compounds. When multiple units are used in series or in combination with other control devices, the packed-bed wet scrubber system can be part of an effective odour control system. Carbon adsorption has been widely used to control both odour-causing compounds and volatile organic compounds (VOCs) in airstreams. The contaminated airstream is brought into contact with carbon media, where the compounds are adsorbed on the carbon surface. Carbon adsorbers are also used as polishing units to remove pollutants that have passed through a packed-bed wet scrubber system. Thermal systems are clearly superior to other technologies in treating VOCs efficiently. Thermal systems can be designed with destruction efficiencies greater than 99%. Thermal processes destroy odours and VOCs by converting them to fully oxidised compounds, through combustion in an environment of excess oxygen. The compounds formed are either nonodorous (e.g., water vapour or carbon dioxide) or less odorous (e.g., hydrogen sulphide converted to sulphur dioxide). Biofiltration has become a popular choice for treating odorous air streams. As odorous air is passed through the biofiltration system, odorous compounds are removed and subsequently oxidised by the microbes growing on the media. There are two main types of biological control units: biofilters and biotowers (biotrickling filters). The remainder of this paper describes design criteria and performance data collected for this form of odour control.BIOTECHNOLOGY-BASED ODOUR CONTROL DESIGN CRITERIAA variety of parameters need to be considered when designing biofilters and biotowers to ensure that the optimum conditions are provided for efficient operations. These factors all have one main goal: to provide a suitable environment to sustain the micro-organisms responsible for the biofiltration process.
Overall, effective odor control measures are essential for industrial facilities. They can help to protect the health and well-being of employees, as well as prevent damage to a company’s reputation. By using specialized equipment and techniques to remove H2S and Mercaptan odors, and ensuring proper ventilation, industrial facilities can create a safe and pleasant working environment for everyone.
As for photos, you may consider including images of the equipment mentioned in the article, such as activated carbon filters, biological treatment systems, chemical treatment systems, ozone generators, and air scrubbers. You could also include photos of industrial facilities implementing these odor control measures, or before and after photos demonstrating the effectiveness of these methods.
