What Fluidyne does

Fluidyne Corp. (Cedar Falls, Iowa, USA; founded 1982/1983) is a privately held engineered-equipment manufacturer specializing in municipal and industrial wastewater treatment technology. The company designs, builds and commissions proprietary treatment systems that target biological nutrient removal (BNR), grit removal, sludge reduction, aeration/mixing and decanting at treatment plants. Its product portfolio centers on five interlocking technology platforms — ISAM™ (Integrated Surge Anoxic Mix) for total BOD/TSS/nitrogen removal with integral sludge reduction; SAM™ (Surge Anoxic Mix) for flow and nutrient equalization, of which Fluidyne was the first US promoter; SBR (Sequencing Batch Reactor) activated sludge systems; Jet MCR™ multi-channel orbital oxidation ditch technology; and Hydro-Grit™ vortex grit separators. Supporting components include fixed and floating decanters, jet aeration/aspiration/mixing subsystems, and an ISAM Sludge Reduction System (SRS) add-on for retrofits. Fluidyne highlights performance metrics of up to 80% sludge reduction, 95% grit removal at 74 micron and above, and effluent quality below 3 mg/L TN, 5 mg/L BOD and 0.2 mg/L phosphorus in documented installs. Multiple products are differentiated by all-hydraulic, no-moving-parts designs intended for 25-year service lives.

The company has supplied equipment for over 40 years with what it claims are hundreds of installations worldwide (300+ SBR plants). Fluidyne sells primarily through direct enterprise field sales, with customers engaging via 'Request More Information' forms and receiving quote-based pricing for custom-engineered systems. Documented customers are municipal water/wastewater utilities and county authorities (e.g., City of Athens TN, Bryan County GA, Hilliard FL, Bellevue OH, Beaver Creek TN, Portugal Cove-St. Philip's and Mabou in Atlantic Canada). Revenue is generated from hardware sales of treatment equipment plus installation, startup and commissioning professional services. Pricing is not publicly disclosed. The company is independently owned with no disclosed external funding, parent company, subsidiaries, or institutional investors; ownership is structured as a traditional private corporation.

The technical and commercial position is that of a niche, reference-rich specialist in BNR and grit removal with patented/trademarked intellectual property, recognized via the 2014 ACWWA Wastewater Treatment Plant of the Year award. Revenue and headcount data are not publicly disclosed; scale proxies (11–50 employees, ~$5M–$25M implied revenue) suggest a small, established engineering firm rather than a venture-backed scale-up. Distribution is direct with a dormant 'Rep Login' portal hinting at prior manufacturer-rep activity. International projects (Canada, others) indicate past global reach but the current data window shows no active geographic or product-line expansion beyond the existing portfolio.

Products and services

• ISAM™ (Integrated Surge Anoxic Mix) Total wastewater treatment system for municipal and industrial applications, incorporating BOD, TSS and nitrogen removal along with integral sludge reduction. Combines an anaerobic selector, SAM tank, and aeration basin in an integrated process with built-in flow equalization and no in-basin moving parts.
• SAM™ (Surge Anoxic Mix) Surge tank system that integrates anoxic and aerobic processes for energy-efficient BOD, TSS, and nutrient removal. Provides flow and nutrient equalization for optimal treatment at varying flows and loadings.
• SBR (Sequencing Batch Reactor) Batch reactor system for wastewater treatment with BOD, TSS and nutrient removal capabilities, with 300+ plants operating worldwide per the company.
• Jet MCR™ (Multi-Channel Orbital) Oxidation ditch technology using jet aeration/mixing to improve nitrogen and phosphorous removal while saving power. Features a three-channel configuration providing carbonaceous removal, nitrification, denitrification, and biological phosphorous removal in a single system with independent control of oxygen transfer and mixing.
