Ozone nanobubble cleaning technology for sustainable, chemical-free disinfection
Nanu Water Tech offers ozone nanobubble (NB) technology enabling invisible, human- and planet-friendly cleaning with zero hazardous chemical residues. Applications include all-natural water-based cleaners, NB-enhanced cleaning products, and on-demand NB spray bottle nozzles for consumer and industrial use.
Overview
Ozone nanobubble (NB) technology from Nanu Water Tech delivers powerful disinfection and cleaning performance without hazardous chemicals, addressing growing consumer and regulatory demand for sustainable cleaning solutions. Ozone NBs combine the oxidizing strength of ozone with hydroxyl radicals released when the bubbles burst, creating a highly effective natural disinfectant. Unlike conventional chemical cleaners, this approach leaves no toxic residues throughout the product lifecycle, making it safe for users, surfaces, and the environment.
Three application pathways are envisioned for industry partners: a water-based ozone NB all-natural cleaning agent, ozone NB-enhanced cleaning products that boost the performance of existing formulations, and a specially designed NB-enabled spray bottle or nozzle that generates nanobubbles on demand at the point of use. Together, these pathways address the primary barriers that have historically prevented ozone NB cleaning from reaching consumers: limited shelf life and inconvenient application.
Technical specifications
- Nanobubble disinfection: Ozone NBs act as strong natural disinfectants by combining ozone with hydroxyl radicals generated when bubbles burst or are triggered to burst.
- Extended longevity: Nanu proposes creating ozone NBs that remain stable in solution for months to years through sealed and pressurized storage, overcoming the shelf-life limitation that has restricted consumer adoption.
- Surfactant carrier function: NBs can transport surfactants into deep nano-scale crevices where oils and grease accumulate, enhancing cleaning efficacy at the microscopic level.
- On-demand generation: Nanu's patent-pending NB generation technology enables the design of spray nozzles and bottles that create nanobubbles at the moment of use, eliminating the need to store unstable ozonated solutions.
- ESG-aligned platform: The underlying nanobubble generator technology is manufactured using additive manufacturing and 3D printing, minimizing material waste and supporting scalable, cost-effective production.
Technology readiness level
The core disinfection properties of ozone nanobubbles have been studied and validated in prior research, and the longevity of nanobubbles in open environments has been demonstrated over multi-month timescales. A commercial precedent exists in Tennant Company's ec-H2O Nanoclean industrial floor cleaning machines, which have used nanobubble technology successfully for over a decade. Nanu's proprietary NB generation method is patent-pending, and the company is currently at the stage of selecting and prioritizing one of three research tracks for initial validation with modest funding, with the goal of aligning development directly with a commercially viable product path.
About Nanu Water Tech
NANU Water Technology Inc. is a climate-tech company founded in 2021 that specializes in affordable, scalable nanobubble generator technology. The company leverages additive manufacturing and 3D printing to produce in-line fluid fitting devices, known as Hyper, which can be integrated into various water systems. These devices allow for the injection of gases such as air, oxygen, ozone, or CO2 to improve water quality, enhance crop performance, and support industrial processes. By designing their technology as a component-based solution rather than a heavy, standalone system, Nanu aims to minimize manufacturing waste and provide a cost-effective, disruptive alternative to traditional nanobubble generators.
The company's technology is built on an ESG-focused framework aimed at mitigating climate change through reduced greenhouse gas emissions, carbon sequestration via direct air capture, and improved water efficiency. Their products are utilized across multiple verticals, including agriculture, environmental management, and healthcare, with applications ranging from modulating microbial biofilms to enhancing regenerative medicine solutions. Nanu collaborates with research institutions and industry partners to validate their technology's performance and impact, and they are actively pursuing carbon credit certifications. Based in Washington, the company provides these solutions to help businesses reduce chemical usage and lower their environmental footprint.
