In this article, we explore the critical role of biofilters in wastewater treatment plants, particularly in managing emissions from processes like sewage sludge drying and screening facilities. Traditional systems often rely on scrubbers to regulate air moisture, but these come with operational and hygienic challenges. We introduce the PureAir Biofilter as a sustainable, reliable, and low-maintenance alternative. Its patented design, intelligent moisture control, and proven success in numerous plants worldwide set a new standard for exhaust air treatment. Learn how our innovative biofilter helps reduce ammonia, hydrogen sulfide, and VOC emissions, providing effective odor and emission control in wastewater facilities.
