Target: Andrea Schäfer and Bryce Richards
Goal: Applaud scientists for inventing a revolutionary water purifier to help improve access to clean drinking water in the developing world
In a world where millions of people lack access to safe drinking water, effective filtration is not always available. Hydraulic engineer Andrea Schäfer and photovoltaics expert Bryce Richards recently partnered to created an effective solar filtration system that can convert polluted water into high-quality drinking water. The results of a successful test run in Tanzania are currently being analyzed at the Karlsruhe Institute of Technology (KIT).
Citizens in third world countries like Tanzania suffer from higher mortality rates due to the many health complications that arise from drinking polluted water. Some of these health complications can be deadly such as water-borne illnesses like cholera. Others affect development such as the teeth discoloration and severe bone deformities in children dependent natural water sources in Tanzania with dangerously-high levels of fluoride. Schäfer and Richards’ filter can both remove harmful bacteria and viruses and reduce the concentration of fluoride to acceptable levels.
This new solar filtration system can be operated with solar or wind power, and works by combining ultrafiltration membranes to remove harmful molecules from the water that passes through the system. After the current testing at KIT the solar filtration system will be installed in select locations. Each system will be able to provide up to 50 people with an ongoing source of clean drinking water.
Inventions such as this water purifier are vital for the improvement of individuals’ lives in the developing world. Applaud the efforts of the scientists who designed and created this solar filtration system for converting polluted water into clean drinking water.
Dear Ms. Schäfer and Mr. Richards,
Thank you for investing a considerable amount of time and effort into the creation of a water purifier that gets rid of bacteria, toxic substances, and viruses. Your invention will be extremely beneficial to the citizens of Tanzania, and anywhere else that the system is eventually used. Inventions such as yours are revolutionary, and all the more so because you are innovating to help improve the quality of life in areas where people lack reliable access to clean, safe drinking water.
Thank you again for this revolutionary and effective creation. I look forward to hearing about the great impact that this invention will have on the lives of the people of Tanzania and other developing nations.
