  1. The BALTO Filtera design for emerging markets project http://www.lib.utexas.edu/maps/africa/kenya.gif Conclusion HOW DOES IT WORK? Abstract Our filtration system utilizes a ceramic filter impregnated with colloidal silver. The ceramic pot is made from a mixture of plant material and clay. Thus, after the pot is fired, the miniscule cavities left by the plant material create a filtration matrix through which the dirty water flows. The ceramic pot filter filters out most impurities by trapping them in the system of pores. Colloidal silver, an antibacterial agent, causes bacteria to die by breaking down the cell walls, thus leaving clean water. The filter flows through the ceramic filter fairly slowly but the flow rate can be increased by first stretching a fabric swatch over the pot’s opening to reduce turbidity before the pot’s filtration process begins. The filter can filter approximately .8 gallons of water per hour. The cart system utilizes a three wheel system in which the two larger wheels carry most of the weight. The third wheel is much smaller and serves mostly as a guide wheel and stabilizer. By keeping the cart form bouncing around, it extends the cart’s life. The cart’s handle’s design is similar to a shopping cart because shopping carts seem to work for all heights and body types. The water containers are easily removable and the cart can be used for alternative purposes once the containers are removed. The Balto: Water Filter and Transport System meets all of our customer needs; it is able to filter, distribute, and transport ten+ gallons of water across variable terrain in rural Kenya. Our design is created out of local resources and utilizes recycled bicycle wheels and as a result is sustainable and cost effective. Our second design challenge is a combination of two of the Design for Emerging Markets (DEM) projects: “Filter Press” and “Put Wheels on Anything”. Our team decided to design a water transportation and filter system for a village in Kenya. Initially we conducted detailed research on the living conditions, economy, and local resources in Kenya, thus determining that the design had to be durable, made of local materials, and easy to assemble and repair.
