Filtering Water

A detailed Summary of Filtering Water


Aim: The aim of the assignment is to purify water to a level in which is safe to drink. There are many different ways to purify water, I will be using a method that was used to purify water more than fifty years ago. It is rarely used now as well as then but I will test it out and see how it works.

Procedure: The way which I have chosen to purify the water takes many steps.

Step 1. Settling. This is when the large particles in the water are allowed to settle to the bottom

Step 2. Filtration. This step has two other steps within it.

(i) First the water has to be filtered through gravel to pickup all the larger particles which did not settle.

(ii) Next it has to be filtered through sand to pick up any par


This graph shows the water cleanliness after the first attempt.

Conclusion: This experiment went very well, I expected that it would take two or more attempts to get it right, and in the end it turned out better than I expected.

In the next go everything went to plan, Step 1 went perfectly again. Step 2(i) was almost as good as last time getting most of the larger floating particles out of the water. Step 2(ii) this time went well, getting absolutely every remaining bit if dirt out of the water. Finally Step 3 made the water safe to drink.
