What Harn R/O Systems does
Harn R/O Systems operates as Komline-Harn, a specialized product division of Komline (a privately-held industrial equipment group operating since 1946), and has delivered reverse osmosis and nanofiltration membrane treatment systems since 1972. The company focuses on custom design/build of membrane treatment plants, retrofits of existing membrane facilities, and ongoing service for municipal, industrial, electric power, food & beverage, agricultural, chemical & pharmaceutical, and environmental/renewables customers in North America. Its core technology stack centers on reverse osmosis and nanofiltration membrane systems, with full in-house capabilities including multi-discipline professional engineering, CAD design, pilot study expertise, pilot unit rentals, and a fully equipped manufacturing facility in Venice, Florida that produces complete turnkey systems under direct quality control.
The business model combines one-time project revenue from custom design/build contracts with recurring aftermarket revenue from parts, service, and the Komline-ProCare support program. Commercial delivery is via enterprise field sales targeting utilities and industrial accounts, supplemented by an e-commerce storefront (shop.komline.com) for aftermarket parts. Pricing is custom quote-based with no public pricing disclosed, and the company participates in the contract procurement process to add engineering value and reduce time and cost for the customer. Product breadth spans core reverse osmosis systems, membrane plant retrofits, pilot filtration units, dedicated PFAS treatment solutions, and operational and membrane-technology advisory services.
As a division of Komline — which owns a portfolio of industrial brands including Komline-Sanderson, Komline-Aerator Solutions, and Komline-FluidQuip — Harn benefits from shared corporate infrastructure in Peapack, New Jersey, while operating its own engineering, manufacturing, and installation workforce. The company has accumulated industry recognition including AMTA Member of the Year (2015), DBIA Best Water/Wastewater Project (2013), and multiple Southeast Desalting Association Outstanding Membrane Plant awards, supporting its positioning in the North American membrane treatment market.

Harn R/O Systems competitors and assessment
Company assessmentDirect peers
- Lenntech: Water treatment solutions provider specializing in RO, filtration, and softening systems for industrial and municipal customers. Comparable as a custom RO system integrator serving overlapping customer segments.
- Evoqua Water Technologies (Xylem): Specializes in water and wastewater treatment solutions including RO and membrane systems for municipal and industrial clients, now part of Xylem. Direct peer offering overlapping design/build, retrofit, and aftermarket service capabilities across the same end markets.
- Pure Aqua: Designs and manufactures RO and water treatment systems for industrial, commercial, and municipal applications with custom engineering and global delivery. Comparable mid-sized RO system integrator targeting similar industrial and municipal end markets.
- Koch Membrane Systems: Designs and manufactures RO, nanofiltration, ultrafiltration, and microfiltration membrane systems for industrial and municipal water treatment. Directly comparable as a membrane systems designer/integrator with overlapping customer segments and technology stack.
Broad incumbents
- Hydranautics (Nitto Group): Major membrane manufacturer supplying RO, nanofiltration, and ultrafiltration elements globally with system integration capabilities. Comparable because it competes for both membrane supply and system design wins in municipal and industrial RO projects.
- 3M Purification: Industrial filtration and water purification division of 3M offering membrane and cartridge filtration solutions for industrial and municipal water treatment. Comparable in industrial/municipal filtration and water treatment, though it is part of a much larger diversified conglomerate.
- Pentair: Global water treatment company offering RO systems and filtration solutions across residential, commercial, industrial, and municipal segments. Comparable in industrial/municipal RO systems, though its portfolio is far broader including residential and pool.
- Veolia Water Technologies: Global water treatment technology and services arm of Veolia, offering RO and membrane systems for municipal and industrial customers. Comparable because it competes for the same municipal and industrial RO design/build projects, but at much larger scale and with broader capabilities beyond membrane systems.
- Toray Membrane USA: Membrane division of Toray Industries producing RO, NF, UF, and MF membrane elements with system design support for water treatment. Comparable as a membrane technology provider competing in the same municipal/industrial RO design/build market.
- Pall Corporation (Danaher): Filtration, separation, and purification specialist serving industrial and municipal water treatment markets. Comparable where membrane and filtration system design overlaps with Harn's industrial process water and municipal offerings.
