Wet scrubber systems are used across industries where odorous gases, corrosive fumes, chemical vapours or airborne particles need to be removed from contaminated air before it is discharged.
Because the scrubbing chemistry can be selected according to the pollutants present, wet scrubbers can treat a wide range of industrial emissions. Common applications include wastewater and sewage treatment, waste processing, anaerobic digestion, food production, chemical manufacturing, pharmaceutical facilities and metal processing.
Exeon’s scrubX™ wet scrubber system is a containerised, modular system designed for industrial applications requiring reliable treatment of pollutants including ammonia, hydrogen sulphide and acidic gases.
Wastewater and Sewage Treatment
Sewage and wastewater treatment facilities can generate significant odour and gaseous emissions from tanks, sludge handling, treatment processes and enclosed buildings.
Hydrogen sulphide and ammonia are common concerns, particularly where organic material is stored or processed. A wet scrubber can capture these gases from the extracted air and transfer them into an appropriately selected treatment solution before discharge.
For applications involving other contaminant profiles, Exeon also provides a wider range of industrial odour and emission control systems, allowing wet scrubbing to be considered alongside activated carbon and biological treatment.
Waste Processing and Recycling Facilities
Waste transfer stations, recycling facilities, composting plants and organic waste sites can produce a mixture of odours, ammonia, sulphurous compounds and particulate matter.
The composition of these emissions can also vary as different materials enter the facility, making a controllable treatment process particularly valuable.
scrubX™ can be configured around the airflow and contaminant loading of the site, with modular units available where higher treatment capacities are required.
Anaerobic Digestion Plants
Anaerobic digestion facilities are another important application for wet scrubbers.
Feedstock reception, pre-treatment, digestate handling and storage can release ammonia, hydrogen sulphide and acidic gases. Exeon’s dedicated scrubX™ systems for anaerobic digestion are designed to treat these demanding emissions before atmospheric discharge.
Wet scrubbing can also be combined with carbon filtration. Exeon has installed a combined scrubX™ and hi-flo™ tank and process extraction system at an anaerobic digestion site, using wet treatment alongside activated carbon polishing within a compact modular package.
Food Production and Abattoirs
Food processing plants and abattoirs can generate odours from cooking, rendering, by-product handling, cleaning and effluent treatment.
Ammonia and sulphurous compounds may also be produced during processing and waste handling. Exeon provides dedicated wet scrubbers for food production and abattoirs to help control these emissions.
The ability to withstand high moisture levels and treat chemically reactive gases can make wet scrubbing particularly useful within these environments.
Chemical and Industrial Manufacturing
Chemical manufacturing, pharmaceutical production, metal processing and foundries may use wet scrubbers to control acidic gases, chemical fumes, VOCs, dust and other process emissions.
The key consideration is not simply the industry but the chemical properties of the contaminants being produced. Airflow, concentration, temperature and the required removal efficiency must all be assessed before the system and scrubbing chemistry are selected.
Exeon’s range of industrial air filtration technologies allows scrubX™ wet scrubbing to be used independently or alongside hi-flo™ activated carbon and airo-flo™ biological treatment.
For industries dealing with corrosive, soluble or chemically reactive emissions, a correctly specified wet scrubber can provide a flexible and effective route to long-term industrial air pollution and odour control.
