Group 063-01: Recyclable Filtration Materials

Tap Water Testing Continued:  Prototype 1 : Inside a water bottle (Layers of Cotton Pads, Charcoal Powders, Shredded Printer Papers) with cotton pad taped to the opening of the bottle Result : The filtered water came out completely black where a lot of the charcoal powder came along with the filtered water. 1) Problems: Charcoal powder too powdery which can pass through the cotton pads and into the filter paper     Possible solutions: Put another water bottle at the bottle of the filter water bottle with layers of printed paper (similar to coffee filters) and layers of cotton pads to catch the charcoal powder from the filtered water Revised Prototype: Result:  The water still filter out black meaning some of the charcoal powder still came through the cotton pads and into the filtered water. However, this time less of the charcoal pass through as the water appears to be less black.  Possible Solution: (1) We decided to filter th...

Tap Water Testing In this week's lab, we tested how well each of our three layers filtered out tap water. To do this, we measured the layer thickness, how much water was to be filtered, how much water was recovered after filtration, the time it took to filter the water through each layer, and the percent efficiency of the filtration system. First Test For our first test, we filtered tap water through a 2.5 inch thick layer of a cotton t-shirt. We used 170 mL of water for this filtration. After we poured the water into the bottle containing a filter, it took 45 seconds for the water filtration to be completed. We measured that we had recovered about 86 mL of water, meaning that our t-shirt filter had a 50.6% efficiency. Second Test For our second test, we filtered tap water through a 2.5 inch layer of paper. This time, we used 190 mL of water, and it took 17 seconds for the water to be done with its filtration. We recovered 152 mL of water in this test, leading to an 80% ef...

The goal of the project is to create a water filter for disastrous situations. The water filtration system will be created from ordinary household items and will be tested for its effectiveness to filter out organic, metal, and bacterial matters in flood water. It is expected that in the end, the water filtration system will be able to produce drinkable water.

Preliminary Design Idea: (Filtration Bottle) Inside a water bottle:  (1 Liter Water Bottle because the amount of water need to be enough until the next amount of water is filtered)  Layers of Charcoal Powder - to filter out organic matters and metal (colored solutions)  Why? Experimentally proven that it can remove coloring from water Each layers of charcoal will not be too thick because it takes the most amount of time to filter Layers of T-shirts - to capture the bacteria (micron sized beads) and remove them from water  Why? It is a tightly woven cloth with tiny holes which can prevent the beads from going through, but still big enough for water to pass through  Layers of Printed Papers - to further filter out the copper solutions (colored solutions) Why? It is thick and absorbent which will be able to absorb the metal components, yet, thin enough for clean water to go through The clean water that is filtered from the filtered ...

Scenarios:   A flood inundates the city and the first floor is covered, we are on the second floor in the house. Our resources are in the bedrooms, the bathrooms, and everything on the second floor. Water has flooded the city and the salt in the sea water has polluted the clean water supply. Location: Coastal Southern United States (i.e. Texas, Florida, etc.) Micron-sized beads of bacteria - grayish color Copper sulfate - blue Organic matter - pink (pink dye) Brainstorm: 1. Possible Materials: Towels Clothing Flashlights Batteries Garbage bags Storage bins Gutters Chair padding Cardboard Tape Waterproof materials from suitcases Camping equipment Electric wire cable Cement Musical instruments Craft supplies Charcoal (carbon) - good for filtering organic matter and copper Tire pump - to pump water from first floor into the filtration system 2.  Initial Design Ideas water passes through charcoal pieces cheesecloth after these filters to remov...
