What DLK Technologies S.A. does

DLK Technologies S.A. is a Swiss industrial water-treatment system integrator headquartered in Le Locle, canton of Neuchâtel, operating as a privately held Société Anonyme since 1995. The company designs, engineers, and delivers turnkey water and effluent treatment solutions to industrial manufacturers, automotive garages and vehicle-maintenance operators, and precious metal processing facilities exclusively within Switzerland, combining biological, physico-chemical, membrane, and electrochemical process technologies. Its core technology portfolio spans fluidized-bed bioreactor (FBR) biological treatment — for which it holds the first Swiss regulatory homologation — the Split-O-Mat physico-chemical line (inherited via the Enviro-Chemie merger), ultrafiltration/nanofiltration/reverse osmosis membrane skids, electrocoagulation cells, the proprietary SX9 electro-separation unit, and integrated vacuum evaporation via its H2O Vacudest reseller relationship, supplemented by Loosli-licensed coalescence pre-treatment and ozone.ch Sàrl ozone capabilities. The business model is direct, consultative, project-based equipment sales paired with recurring service, consumables, and process-optimization revenue from an installed base of Swiss industrial customers, supported by digital channels (notably a YouTube presence launched in April 2020) and apprenticeship/training partnerships including FSRM.

Partnerships

Three partnerships are on record, tiered core.

• Enviro-ChemiecoreStrategic or Co-development PartnerDLK merged with Enviro-Chemie, enabling DLK to expand its physico-chemical treatment portfolio significantly. Through this fusion, DLK gained access to the renowned Split-O-Mat product range, which complements DLK's existing semi-automatic SPA systems. This partnership strengthens DLK's position in the compact physico-chemical treatment segment.
• H2O (H2O-DE GmbH)coreTechnology or IntegrationDLK is a reseller and integrator of H2O Vacudest vacuum evaporators in Switzerland. The Vacudest range (XS, S, and M models) handles highly charged industrial effluents with mechanical vapor compression technology, enabling zero liquid discharge. DLK provides installation, training, service, and maintenance for these systems.
• ozone.ch SàrlcoreStrategic or Co-development Partnerozone.ch Sàrl is a related company that shares infrastructure with DLK. According to DLK's data privacy statement, ozone.ch Sàrl 'rents its name' to DLK, and ozone.ch France Sàrl belongs to ozone.ch Sàrl with personnel and services fully linked to DLK. ozone.ch specializes in domestic and industrial water softeners, reverse osmosis systems, and provides osmometers (Merlin, Spirit/Dometic RO-300, Pro-600) that complement DLK's industrial offerings.

Scale indicators4 records

Recent moves6 records

Expansion highlights5 records

Regional players

• Holinger AG: Swiss environmental engineering and water treatment consultancy offering wastewater and process water solutions to Swiss industrial clients. Operates in the same Swiss market as DLK with comparable customer base in the watchmaking and precision engineering sectors.
• Grünbeck Wasseraufbereitung: German water treatment specialist focused on softening, filtration, and industrial process water. Regionally competitive with DLK in DACH industrial markets, particularly on process water and water reuse for SMEs.

Emerging players

• Fluence Corporation: Decentralized water and wastewater treatment company with industrial wastewater and recycling solutions. Overlaps with DLK on modular treatment systems and zero-liquid-discharge aspirations, though at a different scale and market.
• Organica Water: Specialist in biological wastewater treatment including fixed-film reactor systems for industrial and municipal applications. Comparable to DLK's FBR biological treatment approach, particularly for industrial effluent compliance.

Direct peers

• Enviro-Chemie: Swiss specialist in industrial water treatment and physico-chemical systems, including the Split-O-Mat product line that DLK now distributes following its merger with Enviro-Chemie. Direct competitor and now partner across the same wastewater compliance and recycling use cases in Switzerland.
• H2O GmbH (H2O-DE): German manufacturer of Vacudest vacuum evaporators with mechanical vapor compression — the same product line DLK resells and integrates in Switzerland. Overlaps directly on industrial zero-liquid-discharge and heavy-metal effluent concentration applications.

Broad incumbents

• BWT (Best Water Technology): European water technology group covering industrial water treatment, process water, and recycling. Serves industrial customers with overlapping technologies (membrane filtration, ion exchange, softening) and competes for similar mid-market industrial projects in the DACH region.
• Ovivo: Industrial water and wastewater treatment specialist with municipal and industrial customers across ultrfiltration, biological treatment, and zero-liquid-discharge solutions. Competes in adjacent industrial niches with similar turnkey project delivery model.
• Veolia Water Technologies: Global water treatment major with broad industrial wastewater, process water, and recycling solutions. Competes in same end markets (industrial wastewater compliance, water reuse) but at much larger scale and with broader geographic reach than DLK.
• SUEZ Water Technologies & Solutions: Global water and wastewater treatment provider offering industrial process water, wastewater recycling, and ultrapure water systems — categories where DLK competes at the Swiss SME level. Larger portfolio and global footprint compared to DLK's boutique Swiss offering.
