Cembrane

What Cembrane does

Cembrane A/S is a Danish manufacturer of patented Silicon Carbide (SiC) ceramic flat sheet membranes used in water and wastewater treatment. Founded in 2014 in Lynge, Denmark, the company produces the SiCBlox FX Series — submersible modules containing 42 individually interchangeable SiC membrane sheets that can be stacked up to 15 modules per tower with integrated aeration and permeate lines. The underlying SiC plates are formed by extruding and firing silicon carbide powder at over 2,000°C, then coating with a second SiC layer to create micropores, producing a naturally hydrophilic MF/UF membrane that repels organic foulants including oil. Performance claims include flux rates up to 10x organic membranes, 20+ year operating life, tolerance of up to 50,000 ppm solids, and >95% recovery on sand filter backwash water.

The company operates an OEM and system integrator go-to-market model, selling membrane modules as hardware to B2B partners worldwide rather than directly to end users. It supplements this with the Cembrane Certified Partner Program launched in May 2024, plus regional sales offices in Germany, Singapore, Australia, MENA, and North America. Cembrane holds NSF/ANSI 61 HOT certification for drinking water use up to 60°C, NSF/ANSI 419 certification for cryptosporidium removal, and ISO 9001 compliance at its manufacturing sites. The company was acquired by Ovivo Inc. in November 2021 and operates as a subsidiary within the Ovivo group, which is itself owned by SKion Water GmbH. Manufacturing is conducted at the Lynge, Denmark headquarters and at a 110,000 sq ft facility in Hutto, Texas, opened in 2023 with an Ovivo investment of more than USD 25 million.

Cembrane serves municipal drinking water utilities, industrial wastewater operators, and engineering firms across mining, petrochemical, food and beverage, pharmaceutical, semiconductor, and landfill leachate applications, with its SiC technology deployed in 450+ installations across 60+ countries. Notable differentiated applications include beer tank bottom sludge recovery (via Australian partner AquaVoda) and Northern Norway mining leachate treatment (via Danish partner Aquarden). Revenue is not publicly disclosed and the company operates as a privately held subsidiary, with current reported headcount of 21 employees alongside a planned ramp to roughly 100 at the Texas facility.
