Wastewater Treatment Odor Mitigation

This article provides an overview of the fundamental principles behind wet scrubber systems and their role in mitigating odors in wastewater treatment. Additionally, it presents an examination of the most effective and dependable approach for channeling noxious fumes to the scrubber systems.

In spite of the fact that numerous wastewater treatment plants continue to employ traditional methods that have been in use for decades, there is a growing trend towards adopting a wider range of water treatment technologies. This shift aims to enhance both the quality of water and the purity of the air surrounding these facilities. This article introduces the basics of how wet scrubber systems support wastewater treatment odor control and offers a look at the best and most reliable method for directing odorous fumes to the scrubber systems.

While some wastewater treatment plants still adhere to traditional methods that have been in use for generations, others are adopting a more diverse range of water treatment technologies. This shift is aimed at enhancing both water and air quality. In any wastewater treatment facility, offensive odors can arise from the various processes involved. The primary and secondary treatment systems, as well as biosolids-processing facilities, are the main sources of these odorous emissions. As populations increase and communities expand, controlling wastewater odors has become a pressing issue for many waterworks facilities.

Wet scrubber systems are commonly used for vapor phase wastewater odor control in various areas such as wastewater treatment plants, biogas plants and biosolids treatment facilities. The process begins by extracting process-air from the process and directing it towards the scrubber unit. To prevent the release of contaminants before reaching the scrubber, the air is drawn under negative pressure. The use of corrosion resistant stainless-steel or polyethylene (PE) pipes is crucial in ensuring that process gases and gases emitted through diffuse emission of the treatment facility are extracted to the wet scrubbing unit.

Once the hazardous fumes are transported safely, wet scrubber systems are used to convert the vaporous pollutants into a liquid/ condensate solution. This is achieved by spraying chemical additives and water mists into the scrubber, which solubilize targeted pollutants based on their chemical compounds. The resulting liquid is then purified using various chemicals, including sodium hydroxide (NaOH), which is used to remove hydrogen sulfide (H2S) in a two-stage system. The second stage of the scrubber involves a neutral stage to avoid entrainment of chemical particles to the environment. This stage is also used to add fresh makeup water to compensate the evaporation loss and loss of liquid through drainage. This process effectively removes flammable, toxic, and odorous hydrogen sulfide gas from wastewater treatment systems.

Our scrubbers offer an efficient solution for eliminating harmful acid gases, amines, and organic pollutants from exhaust gas. Scrubbers function by introducing contaminated gas to a washing liquid that contains reagents capable of removing the contaminants. The effectiveness of the removal process is regulated by quality measurements of the washing liquid. Ravebo scrubbers are tailor-made and come in a range of sizes, with materials that can be customized to suit specific process conditions.

Gas scrubbers find diverse applications in industries such as wastewater treatment, chemical and pharmaceutical sectors, plastics industry, metals industry, and incinerator installations. Their suitability for these industries stems from their ability to withstand high temperatures and corrosive substances.
