Future Applications

Environmental Remediation

Our metal sequestration system can be scaled up to filter heavy metals from large, contaminated bodies of water (such as Onondaga Lake). The fiber reactor and filtration systems would fitted inside a durable and buoyant casing, creating a self-sustaining, filtering buoy. A strong pump would suction contaminated water through intake pipes on the belly of the buoy and propel it through the filter. The clean water would then be expelled from the underside of the buoy, disrupting the surface of the water as little as possible. A sixteen square-foot solar panel would provide enough power to run the system and send out hourly updates to maintenance workers. When the filter becomes oversaturated with metals, the buoy would send a notification to workers, who could cruise out to the buoy and replace the modified cells.

Home Use

We want to extend and diversify the function of our heavy metal filtration system. One option is to scale it down for household applications. One potential home use application is a faucet-attached filter for potable water. It would function much like existing solutions that use activated carbon but would instead be targeted at regions at a greater risk for heavy metal contamination. Our design for this is much simpler than the one for environmental deployment. The prefilter, pump, and its supporting electrical system can all be eliminated because a home’s water supply already provides the necessary pressure and consistency. The only components are the hollow fiber reactor and a small reservoir to allow for more time for full sequestration of ions. The reactor itself has been downsized due to lower flow requirements and will fit into a user-replaceable cartridge.



Another possible small scale utilization of the heavy metal filtration system is as a filter attachment for a garden hose. The attachment could possibly serve to filter out heavy metals from water before it reenters the ground or is taken up by plants. (insert fact and source here) There are design problems to consider for this model. Because hollow fiber reactors work best when flow is relatively slow, the water would have to be going slow enough to effectively filter out heavy metals while also going fast enough for an effective spray out the garden hose nozzle. It also can’t be so fast that the fibers are destroyed. The water flowing through the hose is can be assumed to be from tap or well water so large particles are not an issue and the large prefilter can be removed. The force of the water through the hose allows for the elimination of most of our original filtration design, including the wiring, piping, and power sources.

Far far away, behind the word mountains, far from the countries Vokalia and Consonantia, there live the blind texts. Separated they live in Bookmarksgrove right at the coast of the Semantics, a large language ocean. A small river named Duden flows by their place and supplies it with the necessary regelialia.

But I must explain to you how all this mistaken idea of denouncing pleasure and praising pain was born and I will give you a complete account of the system, and expound the actual teachings of the great explorer of the truth, the master-builder of human happiness.

No one rejects, dislikes, or avoids pleasure itself, because it is pleasure, but because those who do not know how to pursue pleasure rationally encounter consequences that are extremely painful. Nor again is there anyone who loves or pursues or desires to obtain pain of itself, because it is pain, but because occasionally circumstances occur in which toil and pain can procure him some great pleasure. To take a trivial example, which of us ever undertakes laborious physical exercise, except to obtain some advantage from it? But who has any right to find fault with a man who chooses to enjoy a pleasure that has no annoying consequences, or one who avoids a pain that produces no resultant pleasure? On the other hand, we denounce with righteous indignation and dislike men who are so beguiled and demoralized by the charms of pleasure of the moment, so blinded by desire, that they cannot foresee.
