Filter systems-experiment

What is filtration?

Filtration is separating solids from liquids by adding a medium through which only the liquid can pass. 

Examples are:


  1.  coffee jug/plunger
  2.  RO unit for fish tanks
  3.  pool filter
  4. water treatment plant that gets water from lake

Aim

Aim: To make a filtration plant using household materials. Water Filtration Plant What is filtration? Filtration  is separating...

Materials

1. Tissue/filter paper
2. Sand
3. Pebbles
4. Scissers
5.large plastic bottle 
6. Dirty water

Process 

Step 1

Cut the bottle at the bottom of the sticker to create a funnel and container

Step 2

Put the funnel in the container 
Step 3
Fold a piece of filter paper and place it in the bottom of the funnel . 

STEP 4

Put sand into the cone shaped paper and gently push down, fill up the cone and around so its level cover the sides too.  

STEP 5

Tip in a layer of pebbles and tap them down

STEP 6

Slowly pour dirty water in the top and watch it become clearer

you can pour the water through the filter again to make it even more cleaner. 

Measurements


Write a short sentence about the water every 1 minute. 
Include 'How much water has filtered through', 'How fast it is dripping through', and 'How clear the water is'.

min 1. A few drips have come through. 

min 5. there is just enough water to have a wee sip 

min 10. there is about a cm of water in the bottom. 

Conclusion

overall our filter worked well. If you were stuck in the desert you could use this filter system to filter some water and live. You could even make two of them to double the power.
