Odor Improvement Products
Odors in the pulp and paper industry often come from hydrogen sulfide, mercaptans, and sulfur dioxide produced during the process. Fortunately, Angel's Improved Air Quality products provide a natural and effective odor control solution to neutralize these and all other odors associated with the paper and pulp industry.

Sources of Odors in the Papermaking Process and Wastewater
During wood cooking (e.g., kraft or sulfite processes), sulfur-containing compounds like hydrogen sulfide and methyl mercaptan are produced, which have strong odors.Wastewater contains significant organic matter from the decomposition of fibers and lignin. Under anaerobic conditions, these break down into gases such as ammonia and hydrogen sulfide.
Odors from Wastewater Treatment
Poor aeration in wastewater treatment systems (e.g., sedimentation tanks, anaerobic units) can lead to anaerobic fermentation, releasing gases like hydrogen sulfide.Biological degradation during sludge treatment can also emit odors.
How to use
Ultrasonic atomization systems and high-pressure microfog are the primary methods for eliminating odor sources, including pulp tanks, binders, recovery plants, pulpers, cooling towers and exhaust stacks. Combine distribution systems to create a complete paper mill odor control program.
