Simple Water Filtration (Clean Your Own Dirty Water)

In this exercise, you will deal with your dirty water, observe the results qualitatively at different stages, and try to propose improvements. Read practical articles and identify separation and purification techniques used

(2) Fold the filter paper in half, then fold it in half. You should be conical. I put it in the funnel

(3) Place another piece of glass on a flat surface and place the funnel on top. Insert half of the dirty water into the cone filter paper in the funnel.

(4) Drop Filter and observe the funnel. Your other glasses should be filled with clean water

(5) When filtration is completed, repeat steps 3 and 4, but use another filter paper. Remove the remaining dirty water and switch it with a glass containing dirty water. Then the filtered water is in your hand and the other is under the funnel.

(7) After completion, add 2 drops of bleach (containing chlorine) to the filtered water. Stir for 1 minute

When dirty water was poured into the filter paper, the dirt did not pass through the filter, but water did not pass. This is because a small hole is opened in the filter paper.

In this lesson we will focus on the filtration and disinfection procedures. This experiment shows that even a simple purification system can help clean dirty water by understanding the physical process of removing solid impurities of different sizes and the chemical process of removing dissolved solids I will. Material: How does water look like? (It helps the students to think about the function of the filter, the effect of the filter, and what can not be filtered out by the filter, even if the water looks clean.) Students need to pass the filter several times to purify the water . Excessive dust from the active filter carbon may make the water slightly gray. In order to save time, you may need to wash carbon beforehand.

Clean water is indispensable to life. Let's think about the frequency of water use everyday - cooking, drinking, washing, washing the dishes, brushing teeth, taking a shower. You do not want this with dirty water, do you? Filtration is an important step of water purification. During the filtration process particles or impurities such as chemicals and bacteria are separated from the filtered solution. Separation methods can be mechanical, physical, chemical or even biological methods. To understand how the water filter works it is best to see the inside of the filter. Most filters used for domestic water treatment are carbon filters. In other words, as shown in Figure 1, the material inside the filter is carbon or its special shape, called activated carbon or activated carbon.
