April 10, 2018 - Week 2


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 bottle will go into another water bottle so that it will only contain clean drinkable water. 

Costs (Prices in USD): [If Brought in Store]
  • Plastic Water Bottles ($2.38)
  • T-shirts ($1.89)
  • Activated Charcoal Powder ($15.73)
  • Printed Paper ($9.99)
Summary:
This week we decided upon a preliminary design including the different materials that we are going to use. We have successfully decided on the three different materials: charcoal, t-shirt, and printed paper. The charcoal will filter the colored solution, the t-shirt will filter out the micron sized beads, and the printed papers will further filter out the colored solution.

According to last week's testing, that prototype failed to filter the blue dye solutions, thus, this week we had to revise our prototype and we decided to add more materials to the system. Prototype 1: Inside a pint container with a hole on the bottom: (a layer of coffee filter, layer of T-shirt, layer of Cotton Pads, Charcoal Powder, more cotton pads on top)   Result: The water still came out black after washing the charcoal several times, thus, the coffee filter and the T-shirt as the bottom layer does not absorb or catch the charcoal powder really well. Also, we felt that the coffee filter does not do anything to the filtration system (rather it absorb the diluted charcoal powder which then come along with the filtered water), so we decided to remove the coffee filter. Prototype 2:  Still, inside a pint container with a hole on the bottom: (a layer of T-shirt, thin layer of cotton pads, a thin layer of charcoal powders, a smaller layer of T-shirt, a tiny bit...

According to last week's testing, the existing prototype still fail to filter out the blue dye solution. Thus, we modified our prototype and decided to use some new materials - gravel - and we decided to mix the sand and charcoal powder and the gravel to see if it will be more effective. New Prototype: Inside a 2 liter bottle: 2 inches of cotton pads, 3 inches of charcoal powder/sand/gravel mix, 1/4 inch of sand, 1.5 inches of gravel We ran all three solutions into this filtration prototype, but we realized that some of the layers are too thick which the filtered water is coming out at a slow pace. And that we had too much gravel, especially in between the charcoal and sand layer. However, we did recognize that the filtered water came out clear which it seems that this prototype is working.  Thus, we recreate this prototype, but this time we remove the gravel from the charcoal/sand layer and reduce some of the gravel on the top layer.  This time, the water came ou...

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...
