HJORTKÆR product offering
Product offeringCore offering
HJORTKÆR designs, manufactures, and sells mechanical wastewater and sludge treatment equipment — primarily screw presses for sludge dewatering, rotary drum screens (TR-series), microfilters, and polymer dosing units — along with auxiliary equipment (grit classifiers, sand traps, screen baskets) and complete turnkey plant solutions. The company's products are sold to municipal wastewater treatment plants and industrial processors (notably food, pulp & paper, and other process industries), and are supported by service and maintenance contracts.
Product overview
HJORTKÆR develops, builds, and delivers industrial machine and system solutions for sludge thickening and dewatering, filtrate optimization, industrial wastewater separation, and polymer dosing. The product portfolio centers on the IEA Screw Presses (delivered since 1991) as the core product line for sludge dewatering, complemented by MF Microfilters for reject water optimization, RDS Rotary Drum Screens for thickening and separation, and PolyUnit Polymer Dosing systems. Supporting equipment includes PW700 Pump Washers for equipment maintenance, ARU Acid Dosing Units for cleaning cycles, CPS1000/CPS1200 Control Panels for process automation, and CT1 IBC Container Mixers. The company also offers mobile rental solutions through H158 and H162 sludge dewatering trailers for temporary or emergency installations.

HJORTKÆR competitors and assessment
Company assessmentDirect peers
- GEA: Through its separation technology division, GEA produces centrifuges and mechanical separation equipment used in sludge dewatering, directly competing with HJORTKÆR's screw press value proposition.
- Huber SE: German manufacturer of wastewater and sludge treatment equipment including screens, thickeners, and dewatering solutions, with a product portfolio that overlaps directly with HJORTKÆR's screw press and rotary drum screen lines.
- Alfa Laval: Supplies decanters and centrifuges for sludge dewatering at municipal wastewater plants and industrial sites, offering a competing separation technology that HJORTKÆR explicitly benchmarks its energy-efficiency claims against.
- SEEPEX: Manufacturer of progressive cavity pumps and related sludge handling equipment used in wastewater treatment plants, with product and application overlap to HJORTKÆR's dewatering and polymer dosing systems.
- Flottweg: Specializes in decanters, centrifuges, and screw presses for sludge dewatering in municipal and industrial applications, competing head-to-head with HJORTKÆR in mid-to-large wastewater treatment tenders.
- Andritz: Global manufacturer of screw presses, centrifuges, and dewatering systems for municipal and industrial sludge treatment, directly competing with HJORTKÆR's IEA screw press portfolio in the same end markets.
Broad incumbents
- Xylem: Major water technology company (including the acquired Evoqua business) offering pumps, filtration, and treatment equipment across the wastewater value chain, serving overlapping municipal and industrial customers.
- Sulzer: Swiss industrial manufacturer with separation and pumping technologies used in wastewater and sludge handling applications, competing in adjacent equipment categories to HJORTKÆR's dewatering portfolio.
- Veolia Water Technologies: Global water and wastewater treatment solutions provider with an extensive equipment and services portfolio, operating as a broad incumbent that overlaps with HJORTKÆR in municipal sludge handling applications.
Others
- IEA Derflinger GmbH: German manufacturer of the IEA screw press line that HJORTKÆR markets and installs. Functions as HJORTKÆR's primary technology partner rather than a direct competitor, though both firms ultimately reach municipal customers through overlapping channels.
