Praise Nonprofit for Breakthrough in Water Purification

Target: James Smith, civil engineer and director of PureMadi

Goal: Applaud development of a simple water purification system that can be mass produced using local materials

PureMadi, a nonprofit University of Virginia organization comprised of students and faculty members from engineering, architecture, medicine, nursing, business, commerce, economics, anthropology and foreign affairs, has developed a water filtration system that can be made cheaply and sustainably. They are currently planning on opening factories in Africa for mass production. If successful, the filter could provide clean water for all of Africa as well as rural areas throughout the world, and for that PureMadi deserves praise.

The MadiDrop, which was developed and tested extensively at the University of Virginia, is a clay tablet resembling a flower pot and is impregnated with silver and copper nanoparticles. Water is poured from an untreated source, such as a river, into the pot where it will filter down into a five-gallon bucket. The pot has a flow rate of one to three liters per hour, which is enough for drinking or cooking. The water is then drained through a spigot in the bucket.

Each filter is made of local clay, sawdust, and water which is pressed into a mold and fired in a kiln. The firing burns off the sawdust, leaving a ceramic material with very fine pores. Finally, the mold is painted with a solution of silver and copper nanoparticles that act as a disinfectant for waterborne pathogens. The filtration of the clay and the disinfectant properties of the silver and copper can remove 99.9% of contaminants from water.

The groups ultimate goal is to create a sustainable business that will help communities and employ local workers. Only a small percentage of the profits will actually be kept by PureMadi in order to be able to build more factories. Eventually, their factories will be capable of producing between 500 and 1,000 filters every month. This would mean clean water for at least 500,000 new families per year who don’t have access to clean water or rely on unfiltered well water. Each filter can serve a family of five or six for two to five years.

Please sign the petition below to thank PureMadi for making clean water possible for everyone and for working to reduce unnecessary deaths from water-born disease.

PETITION LETTER:

Dear James Smith,

Your organization, PureMadi, recently developed a new flowerpot-like water purification system that has the potential to provide clean water to 500,000 more people every year. Not only that, it is made from locally sourced materials and you will be employing people from local communities in your factories. If successful, this could be one of the most important inventions in recent decades.

Thank you so much for this remarkable contribution to the world. There are far too many unnecessary deaths around the world because of a lack of access to clean water. I sincerely hope that your endeavor is a successful one and that the MadiDrop lives up to its potential.

Sincerely,

[Your Name Here]
