Noka

What Noka does

Noka AS is a privately held Norwegian water-treatment engineering and services firm headquartered in Larvik, founded in 1973. The company designs, delivers, and maintains custom drinking-water treatment systems for Norwegian municipal water utilities, with smaller exposure to aquaculture, industrial, and private/household customers. Core offerings center on UV disinfection systems (Trojan UV aggregates, type-approved by the Norwegian Institute of Public Health against the Drikkevannsforskriften) and membrane filtration (nanofiltration and ultrafiltration), complemented by spare parts, operational chemicals, water analysis, and nationwide field service.

The underlying technology stack is physical and process-engineering rather than digital: UV-C at 254 nm for pathogen inactivation (Cryptosporidium and Giardia), NF/UF membrane modules with associated pressure vessels, dosing systems, PLC controls, and pre-filtration via Amiad automatic filters. Noka positions itself as a system integrator and custom engineer rather than a standardized-equipment vendor, designing each installation to the specific raw-water characteristics (UV transmission, color, capacity) of the customer. The firm is also the authorized Norwegian distributor for Trojan UV, Pentair, Hach analytical instruments, and Amiad, which gives it a channel position for major international brands in the domestic market.

The business model is sales-led B2B with a request-for-quote engagement model and multi-year service contracts. Revenue is generated from project hardware sales (UV systems, membrane plants), recurring service and maintenance, spare-part replacement (lamps, ballasts, quartz glass, sensors), and consumables (operational chemicals). Go-to-market is direct sales with a small engineering team (8 listed employees) covering all of Norway; pricing is not publicly disclosed and is set per project. The customer mix is anchored by Norwegian municipal waterworks (including IVAR IKS, one of the country's largest UV installations) with a long tail of cabins, households, aquaculture sites, and industrial users, and the firm completed a corporate merger in 2024.

Scale indicators4 records

Recent moves6 records

Expansion highlights4 records

Regional players

• Hatenboer-Water: Dutch specialist in industrial and drinking water treatment with a strong engineering and aftermarket service model across Benelux and Europe. Comparable niche engineering services plus equipment distribution profile, though not active in Norway.
• Lenntech: Lenntech is a Dutch water treatment solutions provider offering UV, RO, and filtration systems across Europe. Comparable niche engineering-and-distribution model but primarily serves continental Europe rather than Norway.

Direct peers

• Amiad Water Systems: Amiad manufactures automatic self-cleaning filters and strainers for fresh and seawater applications — Noka is Amiad's new Norwegian distributor. They overlap with Noka's filtration offering and could compete directly if Amiad chooses to serve end customers in Norway.
• Pure Aqua: Pure Aqua designs and manufactures water treatment systems including membrane and UV solutions for municipal and industrial clients. Comparable custom-engineered systems model to Noka, though with broader geographic reach and a more export-oriented business.
• Trojan UV (De Nora): Trojan UV is Noka's primary UV technology supplier and a global leader in UV disinfection for drinking water. They are directly comparable as UV system providers and even share a reference customer (NYC water), but compete with Noka when Trojan sells direct internationally.

Broad incumbents

• Xylem: Xylem is a global water technology company (owner of Wedeco UV, Flygt, etc.) providing UV disinfection, membrane filtration and pumping to utilities and industry worldwide. Comparable to Noka in product scope but vastly larger scale, broader portfolio, and global service network.
• Pentair: Pentair is both a Noka distribution partner and a global water treatment provider across residential, commercial, industrial, and agricultural segments. Comparable product portfolio (filtration, treatment) but at vastly greater scale and brand reach.
• SUEZ Water Technologies & Solutions: SUEZ provides municipal and industrial water treatment, including disinfection and filtration technologies. A broad incumbent competitor for Norwegian and European utility tenders where Noka also competes.
• Veolia Water Technologies: Veolia designs and delivers municipal and industrial water treatment solutions including disinfection and membrane systems. Overlaps with Noka on UV and membrane for utilities but operates at multinational scale with bundled EPC and operations services.

Others

• Hach (Danaher): Hach supplies analytical instruments and reagents for water quality testing; Noka is a certified Hach dealer in Norway. Not a direct competitor but an adjacent ecosystem partner whose products are embedded in Noka's service offering.
