Technologies that filter water and make it pure for people to consume

September 29, 2019


There are millions of people on the Earth who do not get safe and clean water for consumption. As there is only 1% of the available water in the Earth as drinking water, rest of the people have to consume water which is not safe for human consumption unless it is treated and made drinkable. Every day scientists try to get a solution to this problem using or inventing different technologies to filter water and make it pure for people to consume.

Top 3 technologies to filter water

1. Tiny water purifier



Water purification systems are often expensive and time-consuming, but researchers at Stanford University and SLAC National Accelerator Laboratory recently developed a UV water purifier housed in a tiny black rectangle that cuts the lengthy process down from 48 hours to around 20 minutes. Although the device is a long way from mass production, lab tests on the prototype suggest that it could be the first step toward a new generation of water purification methods that help make dirty water drinkable.

2. Nano water chip

The cost of clean water is a major obstacle for many thirsty people on Earth, so researchers look for affordable solutions for small scale, personal water purification. In 2014, a joint research team from the University of Texas at Austin and the University of Marburg in Germany developed a low-drain "water chip" which generates a small electrical field to desalinate seawater. Early in its development, the water chip promised to offer a portable clean water solution capable of running on a regular battery. The startup Okeanos Technology was founded to further the product's research and development, which is still underway.

3. The Worlds largest fog harvester

The world's largest fog harvester uses giant mesh fences to trap dense fog in the Moroccan desert and turn it into clean, fresh water. With a surface area over 600 square meters, the contraption takes advantage of the fog blanketing the drought-stricken Aït Baâmrane region for six months out of the year. The fog harvester reportedly produces as much as 17 gallons of clean, safe drinking water per square yard of net. Solar-powered pumps, along with a system of pipes, deliver the clean water to 400 local residents, who ordinarily struggle to gain access to safe water in the arid region.
