Water filter treatment system at the household level. They learn about the importance of water and its role in our everyday lives. Ask students to work in their engineering design groups to design the best water filter system given the filter material options and their choice of aerated or non aerated water. Filtration is one of the most effective yet simplest water treatment processes.

Water flow rate tests are carried out to optimize water filter design. More thorough filtration can be achieved with a slow sand filter or reverse osmosis. Have them record and explain their choices on the worksheet. Sawyer filters have very strong fibers see fiber strength study and are capable of handling up to 40 psi pounds per square inch of pressure.

As the fibers collect particulates the pressure to move water through will increase as the particulates create barriers to water flow. Contaminated water is the number read more.
