FAQs
- What is the Sunlight Activated Water Purification Bag?
- It is a 3-litre reusable water purification bag that uses advanced nanotechnology and sunlight to treat contaminated water. It is designed to address microbes, organic pollutants and heavy metals in a single portable system.
- How does the purification process work?
The system integrates two treatment stages: sunlight-activated photocatalytic nanofibre membranes that inactivate bacteria and viruses and degrade organic pollutants, and a carbon-zeolite adsorption cartridge that removes heavy metals and residual contaminants.
- Does it require electricity or chemicals?
- No. The system is powered by sunlight and does not require electricity, batteries, or chemical purification tablets.
- What types of contaminants does it address?
- The technology is being developed to address bacteria and viruses, organic pollutants, and heavy metals such as cadmium, chromium, zinc, lead and nickel.
- Who is developing the technology?
- The product is being developed by Clean Drinking Water Solutions Pty Ltd in collaboration with the Global Innovative Centre for Advanced Nanomaterials (GICAN) at the University of Newcastle, Australia, under the leadership of Laureate Professor Ajayan Vinu.
- What is the capacity of the bag?
- The purification bag has a nominal capacity of 3 litres and is designed to be lightweight, portable and reusable.
- What stage of development is the project currently in?
- The underlying materials have undergone laboratory validation, and the project is progressing from proof-of-concept toward system integration, pilot production and commercial deployment.
- Who is the product designed for?
- The system is intended for use in humanitarian and disaster relief settings, rural and remote communities, defence and expedition environments, and public health and community programs.
- Is the product environmentally sustainable?
- Yes. The bag is reusable and powered by sunlight, reducing reliance on single-use plastic water bottles and eliminating the need for chemical dosing.
- How can organisations get involved?
- Clean Drinking Water Solutions is engaging with government agencies, humanitarian organisations, manufacturers and investors to support pilot programs and commercial deployment. Enquiries are welcome via our Contact page.
