There are various industrial air purification methods, and the choice of a specific one depends on the type of pollutant (particulate matter, gases, or aerosols), particle size, and industry requirements for safety, cleanliness, explosion protection, and cost effectiveness.
Dry methods are a universal solution for capturing solids of any size, including toxic active pharmaceutical ingredients (APIs), allergens in the food industry, and fibrogenic dust in the production of building materials. They provide dry product collection and achieve efficiencies of up to 99.99% when using HEPA/ULPA filters.
Wet cleaning is indispensable in the chemical and metallurgical industries, where simultaneous removal of aggressive gases, cooling of high-temperature streams, and neutralization of explosive dusts are required. However, it is associated with the generation of liquid waste and higher operating costs.
