Filtering process

Our Aim: To make a filtration plant using household materials.

Water Filtration Plant

What is filtration?

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

Examples are:

1. Coffee Grounds or beans 
2.  Water Purifier
3.  Tea Bags
4. Aquarium filters

Materials

1.A bottle top

2.The bottom of the bottle

3. Rocks

4. Elastic band

5. Coarse sand

6. Fine Sand

7.  Coffee filter

8. Dirty Water

Here is the process

Step 1

Cut the bottle in half.

Step 2

Put the top half upside down and into the other half of the bottle.

STEP 3

Add layers of  first the coffee filter which will be held in place by the elastic band, then the fine sand, the coarse sand and finally, the stones

STEP 4

Get 1 cup of dirty water.

Step 5

Pour dirty water into our homemade filter.

STEP 6

Observe the experiment and look at what is happening with the water and the filter.

Measurements

The water has been going quite rapidly.

The filter as we could see has taken off the big chunks of specks of dirt.

The colour of the water looks almost exactly the same as when it came it, however, there are less grime and muck.

In conclusion, the filter has worked reasonably well; it has filtered the water well though not well enough to drink of course. 

We have learnt more about how filtering works and its uses throughout the world.

The experiment has been successful and has done what we have a hypothesise.

Warning

Make sure that an adult cuts the bottle in half. This water filter is just an experiment and should not be used for drinking water.

Avoid using charcoal briquets, as these can contain chemicals you don't want in your water. Use the activated carbon for water purifiers instead.
