According to recent WHO statistics about 1.1 billion people in the world don’t have access to safe drinking water and about 2 million people die each year due to water borne diseases. The problem is aggravated in the developing countries, which have limited resources to purchase expensive water purifiers and don’t always have access to electricity to power these high-tech water purifiers. The Nano Filter concept has been designed to solve this global problem.
The filter makes use of a fine mesh cotton filter with embedded silver nano wires. While the cotton mesh removes large pieces of debris from water, nano wires kill all harmful pathogens present in the water. The nano wires are excited by a small electric current, which is generate by solar panel strips onboard the Nano Filter.
The system can be used in both rural and urban world to provide access to safe drinking water. The product is especially useful in areas where people do have access to water sources, but mostly all these sources are contaminated. The device is being slated to be better in filtering water than the conventionally used charcoal filters, which are both slow and impractical for filtering large quantities of water.
