- What materials can i use as suitable filters in a simple water filtration system?
After some research on homemade water filtration systems, i came to a conclusion that sand and cotton were among one of the most commonly used filters in water filtration systems and are also easy to obtain. Hence, i decided to test these two filters in the water filtration system that i had created to observe which was the better filter
- How can i create the water filtration system?
These are the diagrams which display the steps to create the water filtration system.
Step 2: Cut one bottle into two segments, with the top segment taking up ¼ of the bottle and the bottom segment taking up ¾ of the bottle.
Step 3: Cut the other bottle into two segments,
with the top segment taking up ¾ of the bottle and the bottom segment taking up
¼ of the bottle
Step 4: Invert the top segment from
step 3 and fit it into the bottom segment in step 2.
Step 5: Invert the top segment from step 2 and fit it on the top.The final product should look like this.
- Testing of prototype
Step 1: Name the 3 filtration systems “Control” “Set-up 1” and “Set-up 2”
respectively
Step 2: In the control, place filter paper at both funnels
Step 3: Pour 50ml of dirty water into the top funnel
 |
| This is the difference between the contaminated water (in the large bottle) and the filtered ' water (in the 50ml beaker) |
Step 4: Wait for all the water to drip to the bottom of the filtration
system
Step 5: Measure the pH level of the filtered water.
Step 6: Add 20ml of sand onto both filter papers and repeat steps 2 – 5
for set-up 1
Step 7: Add cotton onto both filter papers and repeat steps 2 – 3 for set
up 2.
