Air Pollution and Odor Control

Air Pollution and Odor Control

Exhaust gases from different production and environmental facilities differ greatly in pollutant composition, concentration, air flow rate, humidity, and variability. As such treatment solutions are combined and configured to the actual characteristics of the waste gas. For wastewater treatment plants, sludge workshops, waste transfer stations, chemical and pharmaceutical plants, electroplating and surface treatment, spray coating and printing, and food processing, we provide air pollution and odor control solutions ranging from 1,000 to 100,000 m³/h. The main pollutants are odorous gases, VOCs, acid and alkaline mists, and particulate matter.

Selecting Treatment Solutions Based on Exhaust Gas Sources
Application Primary Pollutants Gas Characteristics Recommended Solution
Wastewater treatment plants, pumping stations, sludge workshops Odorous gases such as NH₃, H₂S, and methyl mercaptan Low concentration, large air volume, high humidity Scrubbing, biological deodorization, and activated carbon
Waste Transfer Stations, Composting Facilities Ammonia, amines, and complex odors Large concentration fluctuations, may contain dust Dust removal, spray scrubbing, biological deodorization, and low-temperature plasma
Chemical, Pharmaceutical, Coating, and Printing VOCs, organic solvents, etc. Complex composition, some components are flammable and explosive Pre-treatment, adsorption concentration, and combustion
Electroplating, Surface Treatment, Chemical Acid mist, alkali mist, chromic acid mist, etc. Highly corrosive Mist removal and multi-stage spray scrubbing
Food and Fermentation Cooking fumes, organic acids, fermentation odors Contains oil and water, prone to adhesion Pre-treatment and scrubbing or biological treatment
