Hydro-Dyne

What Hydro-Dyne does

Hydro-Dyne Engineering, Inc. is a private, founder-led manufacturer founded in 1978 and headquartered in Clearwater, Florida. The company designs, fabricates, assembles, and tests screening, screenings handling, and grit removal equipment for municipal and industrial water and wastewater treatment facilities, all from a vertically integrated 110,000 sq. ft. manufacturing facility. Its product portfolio spans fine and coarse screening (Great White Center Flow, Bull Shark Through Flow, Tiger Shark Multi-Rake, Sawshark, Sidehill Shark), specialty screens for septage and low-flow applications (Dusky Shark), screenings handling systems (Whitetip Washing Compactor, Thresher Washing Machine, Spinner Shark conveyors), grit removal (Sand Shark family), and packaged headworks (Reef), with equipment flow capacities ranging from 0.1 mgd to 160+ mgd.

Core technology rests on a set of granted patents covering a sealing system that holds 0.5mm tolerances between panels and grid, direct drives that isolate the grid from the drive mechanism, and a continuous-belt with slotted-grid design for water-only offloading. These underpin independently certified Screening Capture Ratios of 93.25% (2mm grid) and 84% (6mm grid) and quantifiable outcomes such as 80% weight and 85% volume reduction, up to 95% organic removal in washing compactors, and up to 40% dry solids content in dewatered screenings. The proprietary Hammerhead On-Site Screen Sizing (H.O.S.S.) service characterizes site-specific influent conditions for optimal screen selection. The company is Build America, Buy America compliant (Manufacturer of Record) and ISO 9001:2015 certified.

Hydro-Dyne monetizes primarily through custom-engineered capital equipment sales to municipal and industrial buyers, supplemented by a growing service business covering on-site inspections, 3- and 5-year extended warranties, and a remanufacturing/retrofit line that rebuilds existing headworks equipment. Go-to-market is enterprise field sales to specifiers, plant operators, and system designers, augmented by an expanding manufacturer's representative network across U.S. municipal and industrial markets. The company serves municipal wastewater treatment, industrial process and compliance applications (food, chemical, pulp and paper, refining, mining), correctional facilities, and MBR membrane protection, with 2,500+ unique installations worldwide over 45+ years.
