WebAug 11, 2024 · It has been argued that because most PAHs are particle-bound, scrubbers can play a positive role by reducing the particulate content of the smokestack emissions ( IMO, 2006 ). Both atmospheric deposition and scrubber water discharge can result in the accumulation of particle-bound PAHs in sediments. WebAchievable Emission Limits/Reductions: Scrubbers are capable of reduction efficiencies in the range of 50% to 98%. The highest removal efficiencies are achieved by wet scrubbers, greater than 90% and the lowest by dry scrubbers, typically less than 80%. Newer dry scrubber designs are capable of higher control efficiencies, on the order of 90%. WebJun 20, 2024 · Businesses developed more powerful air pollution control technology, like smokestack scrubbers, to reduce emissions. Acid rain, which can deplete soil nutrients, leak into streams, and cause a loss of aquatic diversity is now less frequent. Health-wise, pollution that would have triggered asthma and other respiratory issues was reduced. orbs bookshop
