Air Diffusion Systems

Air Diffusion Systems (ADS) is a family-owned, multi-generational manufacturer of fine bubble aeration equipment based in Gurnee, Illinois, with over 60 years of continuous operation under the leadership of President and Owner John Hinde. ADS diffusers are distinguished by their use of evenly spaced air releases rather than closely spaced holes or pores, producing what the company describes as clog-free operation with minimal power input. Systems are independently certified to ASCE oxygen transfer standards, delivering 3% SOTE per foot of water depth, and operate at 3 to 6 times the efficiency of high-speed surface aeration and 2 to 4 times the efficiency of competing diffused aeration systems. Operational costs are typically less than $0.01 per capita per day, with only one moving part (the blower). ADS offers a 5-year product and treatment guarantee, and many installed systems have operated for 20 to 40 years. The company provides linear fine bubble diffusers and disk module diffusers, along with Sludge Reducing Bacteria (SRB) for biological reduction of accumulated bottom sludge. Applications span municipal and industrial wastewater aeration, aerated-facultative lagoon treatment, lake and reservoir restoration, harmful algal bloom mitigation, potable and industrial water storage tank aeration, air sparging for VOC-contaminated groundwater, ice prevention at marinas and docks, and aquaculture aeration for catfish, shrimp, tilapia, and other species.
