What Duperon does

Duperon Corporation, founded in 1985 by Terry L. Duperon in Saginaw, Michigan, designs and manufactures liquid/solids separation equipment for municipal and industrial water and wastewater applications. The company sells a portfolio of bar screens (FlexRake platform variants including IQ, IQ2, FP, FPFS, FRHD, GTS, Low Flow), the Self-Cleaning Trashrack, Dual Auger System, Washer Compactor, Shaftless Screw Conveyor, Sluice, Low Flow System, and an Internally Fed Drum Screen, with 25 granted or pending patents covering its core technologies. Its underlying engineering architecture emphasizes simplicity, deck-level maintenance (eliminating confined space entries), and adaptive operation under variable debris and flow conditions through proprietary FlexLink, Thru-Bar, Jam Evasion, and SmartLink subsystems.

Duperon operates a project-based direct sales model through regional sales managers and a rep network covering all 50 U.S. states and select international markets, with quote-based pricing driven by RFQ processes typical of municipal procurement. Revenue is generated primarily through equipment sales (hardware) supplemented by a replacement parts and aftermarket stream (Full-Circle Customer Care) and technical services including installation guidance, controls guidance, and a pilot test program for the drum screen. Target customers are municipal wastewater treatment facilities, collection systems and pump stations, flood control and stormwater operators, and industrial sites in food & beverage, pulp & paper, and power generation.

The company is privately held and family-owned, with CEO Tammy Bernier (who has led roughly 25% annual growth over the past two decades), Founder Terry Duperon, and President Mark Turpin (co-owner since March 2026). The firm holds ISO 9001:2015 certification (zero findings on initial 2022 audit and May 2025 recertification), is led from a 70,000 sq ft Saginaw headquarters, and reports 51-100 employees.

Core offering

Duperon designs, manufactures, and services liquid/solids separation equipment for municipal and industrial water and wastewater applications. Its portfolio centers on the FlexRake family of bar screens, Self-Cleaning Trashracks, Washer Compactors, Dual Auger Systems, conveyance equipment, and integrated Low Flow systems, supported by a Full-Circle Customer Care program for parts, technical assistance, and pilot testing.

Product overview

Duperon offers a comprehensive portfolio of preliminary liquid/solids separation technologies centered on its FlexRake® platform and related screening, debris management, and wastewater systems. The core FlexRake® product line includes multiple variants—FlexRake IQ® and IQ2® (intelligent responsive systems), FlexRake® FP/FPFS (full penetration coarse/fine screens), FlexRake® FRHD (heavy duty), FlexRake® GTS (high solids), FlexRake® Low Flow, and FlexRake® Only (retrofit raking device)—each engineered for specific debris conditions, flow requirements, and applications. The Dual Auger System addresses flushable wipes challenges, while the Self-Cleaning Trashrack (SCT) handles severe open channel conditions. Debris management is completed through the Washer Compactor (with optional Discharge Extension), Shaftless Screw Conveyor, and Sluice systems. The Low Flow System integrates FlexRake technology with washer compactor for small community applications, and the Internally Fed Drum Screen (pilot program) addresses fine screening for high-flow, high-solids sites. All products share Duperon's core technology principles: FlexLink™ adaptive technology, Thru-Bar™ cleaning, Jam Evasion™, and SmartLink™ systems designed for simplicity, minimal maintenance, and long product life.
