Dr. Sreenath Bolisetty, Senior Scientist at ETH Zurich University (Department of Health Sciences & Technology), commissioned and supervised analytical testing of the Swiss Water Cartridge (20" POE Water Filter Cartridge) from Mam Nature Swiss AG. The filter incorporates a media developed at ETH Zurich University based on an amyloid-carbon platform.
Testing was performed with validated methods (ICP-MS/ICP-OES, EPA 537M for PFAS, fluorometry, and gamma counting/scintigraphy for radionuclides) under standard QA/QC. The cartridge is designed for whole-house application with flow rates of >1,800 Liters/h.

Peer-reviewed publication in Environmental Science: Water Research & Technology (Royal Society of Chemistry), Vol. 6, No. 12, December 2020, pp. 3249-3254. DOI: 10.1039/d0ew00693a

The study demonstrates that amyloid-carbon hybrid membranes (composed of whey protein amyloid fibrils and activated carbon) are highly efficient at removing clinically relevant radioactive compounds from hospital wastewater by single-step filtration. The technology converts large volumes of radioactive liquid waste into low volumes of solid radioactive waste.
The membranes were tested with multiple filtration cycles showing no saturation — removal efficiencies remained consistent. Real clinical wastewater from Inselspital in Bern (Switzerland) containing I-131 and Lu-177 was successfully purified to below detection levels.
Control membranes (cellulose + carbon without amyloid protein) showed only 34.5% Lu-177 removal and 3% I-131 removal, confirming that amyloid fibrils are the active radionuclide-adsorbing component.
Scalability was demonstrated using a Pulcino® crossflow filter setup with three large membranes (20 × 10 cm), processing ~4 liters of Tc-99m solution by gravity flow alone — no external energy required. After filtration, radioactivity was 0.000 MBq (below detection).
