What Nanostone Water does
Nanostone Water, operating as a brand of Acuriant Technologies following its July 2025 merger with Solecta, is a private membrane solutions company specializing in ceramic ultrafiltration (CUF) technology. Founded in 2012 and headquartered in the United States with its ceramic membrane production facility in Halberstadt, Germany, the company engineers and manufactures ceramic membranes from proprietary nanomaterials (alumina, zirconia, titania) in an ISO 9001, ISO 14001, and ISO 45001 certified automated factory. Its core product portfolio includes the CUF|Shield module (formerly CM-151), the higher-capacity CUF|Flow module delivering up to 40% more water per footprint, the CUF|ShieldPlus module for semiconductor wastewater, and a Containerized CUF System providing up to 10 MLD of RO-ready permeate. The technology is differentiated by a patented segmented monolith design, a 30 nm nominal pore size, and demonstrated performance of 3-5x higher flux and 2-6x longer membrane lifespan compared to polymeric alternatives.
The company sells primarily through enterprise field sales targeting municipal water utilities and large industrial customers across power generation, semiconductor manufacturing, mining, and desalination. Revenue is generated through hardware sales of membrane modules and containerized systems, complemented by engineering, project management, and service revenue, with a Site Pilot Program enabling prospective customers to validate performance at their own facilities. Channel partnerships have expanded significantly, tripling in 2024 to include Pureflow (North America), Metro Pacific Water (Southeast Asia), and regional partners across MENA and Asia. Flagship relationships with ENOWA (NEOM brine mining), ACWA Power (GCC seawater pretreatment), Maynilad (100 MLD Putatan retrofit in the Philippines), PureGen Classic (Malaysia semiconductor reuse), and Severn Trent (Homesford WTW in the UK) demonstrate commercial traction across multiple high-value verticals and geographies.
Nanostone reported 70% revenue growth in 2024, expanded new applications by 50%, and received a $30 million growth investment from True North Venture Partners in 2022. Its 24+ granted patents span the US, Germany, Europe, China, Japan, Korea, Singapore, and Australia, and its technology has cleared key regulatory gates including NSF/ANSI 60 certification and UK Regulation 31 approval for drinking water treatment. Following the Solecta merger, the combined Acuriant Technologies entity offers a hybrid ceramic-polymeric membrane platform aimed at lowering lifetime filtration costs across the most demanding water and process separation applications globally.
