CUF|Flow™ Wins 1st Prize for Innovation at Sapphires of Entrepreneurship 2025

Nanostone, an Acuriant Brand, is proud to announce that our new CUF|Flow™ ceramic ultrafiltration (UF) module has received 1st prize in the “Innovation” category at the Sapphires of Entrepreneurship 2025, awarded by the combined chambers of commerce of Germany, Poland, and the Czech Republic.

CUF|Flow™ sets a new standard in ceramic UF technology. Known for long-term durability, stable flux, resilience under challenging water conditions, and PFAS-free materials, ceramic membranes have always led in life-cycle cost and operational performance. However, adoption in some projects has been limited by initial costs, not capability.

CUF|Flow™ closes that gap. By offering approximately 40% more active membrane area within the same module envelope, CUF|Flow™ delivers up to 40% more water in the same footprint, or the same output with around 30% fewer modules. This breakthrough enables operators to integrate high-performance ceramic UF in projects where it was previously considered too costly, combining technical excellence with financial accessibility.

The result is that municipal and industrial operators can now benefit from all the proven advantages of ceramic UF, including long-term reliability, robust performance, and sustainable PFAS-free materials, while meeting budget and space constraints.

This award highlights Nanostone’s commitment to innovation and practical solutions for water treatment, demonstrating how CUF|Flow™ is reshaping what is possible in municipal and industrial applications.

CUF|Flow™ is not just a technical leader; it is now an accessible, sustainable, and high-performance solution for water treatment operators worldwide.
