Ammonia Scrubber is a specialized air pollution control device used to remove ammonia (NH3) from industrial exhaust gases, ensuring a cleaner and safer environment. It operates by passing ammonia-laden air through a scrubbing liquid, typically an acid solution like sulfuric acid, which reacts with ammonia to form a neutral salt. Ammonia scrubbers are widely used in industries such as chemical manufacturing, fertilizer production, wastewater treatment, and livestock facilities. Ammonia scrubbers help industries comply with environmental regulations, reduce odor emissions, and prevent harmful ammonia release into the atmosphere, making them an essential solution for effective air pollution control and workplace safety.
