Fluidyne
About
Fluidyne is a US-based manufacturer of proprietary wastewater treatment process equipment, supplying municipal and industrial wastewater treatment systems for over 40 years. The company's flagship ISAM (Integrated Surge Anoxic Mix) system provides complete wastewater treatment incorporating BOD, TSS, and nitrogen removal with sludge reduction in a single integrated process where raw sewage enters a covered anaerobic reactor for pretreatment, sludge thickening, and hydrolysis of complex organic solids. The SAM (Surge Anoxic Mix) tank serves as a standalone process control component for anoxic mixing. Fluidyne's SBR (Sequencing Batch Reactor) performs biological oxidation, sedimentation, nitrification, and denitrification within a single tank, featuring a patented fixed solids-excluding decanter with no moving parts in the basin. The Jet MCR (Multi-Channel Orbital) upgrades existing oxidation ditches by replacing surface rotors with jet aeration and mixing to improve nitrogen and phosphorus removal while reducing power consumption. For headworks treatment, the Hydro-Grit system provides vortex grit separation in both high-efficiency and standard-efficiency configurations, paired with a dedicated Grit Classifier for washed and dewatered grit disposal. Fluidyne's jet aeration, aspiration, and mixing systems deliver high oxygen transfer and complete mixing for SBRs, oxidation ditches, extended aeration, and BNR applications. Fixed and floating decanters provide effluent withdrawal. The company serves small-to-medium communities, food processing plants, dairies, chemical plants, and municipal wastewater utilities across North America, with installations in Athens TN, Bellevue OH, and Mabou NS.
