Good morning everyone.
Today I am going to explain my science exhibition project on “Water Purification Working Model.” This is a simple DIY project that demonstrates how dirty water can be cleaned using different natural filtering materials.
Water purification is an important process because clean water is necessary for drinking, cooking, farming, and healthy living. This model explains how impurities can be removed step by step using different filtration layers like stones, sand, and tissue paper.
This project is easy to make and helps students understand the importance of clean water and filtration systems.
Aim of the Project
The main aim of this project is:
- To demonstrate water purification
- To explain the filtration process
- To understand how impurities are removed from water
- To spread awareness about clean drinking water
Explanation of the Model
The model contains multiple filtering stages arranged like steps.
The stages include:
- Big stones
- Small stones
- Sand
- Tissue paper
- Purified water collection
Dirty water enters from the top and passes through each stage. At every level, impurities are filtered out, and cleaner water comes out at the end.
Parts of the Water Purification Model
1. Big Stone Layer
The first cup contains big stones.
Function:
- Removes large particles
- Stops leaves, mud, and large waste materials
This is the first filtration stage.
2. Small Stone Layer
The second cup contains small stones or gravel.
Function:
- Filters smaller dirt particles
- Helps improve water clarity
This acts as secondary filtration.
3. Sand Layer
The third cup contains sand.
Function:
- Removes fine dust and suspended impurities
- Makes the water cleaner
Sand filtration is commonly used in real water treatment systems.
4. Tissue Paper Layer
The fourth cup contains tissue paper.
Function:
- Performs fine filtration
- Removes tiny remaining particles
This stage improves water quality further.
5. Purified Water Container
The last cup collects cleaner water after filtration.
The water becomes clearer after passing through all layers.
Working Principle
This project works on the principle of:
Filtration
Filtration is the process of separating solid impurities from liquids using filtering materials.
Different layers remove different sizes of impurities.
Working of the Water Purification Model
Step 1 – Pour Dirty Water
Dirty water is poured into the first container.
Step 2 – Big Stone Filtration
Large impurities are removed.
Step 3 – Small Stone Filtration
Medium-sized particles are filtered.
Step 4 – Sand Filtration
Fine dirt particles are trapped.
Step 5 – Tissue Filtration
Tiny impurities are removed.
Step 6 – Clean Water Collection
Cleaner water is collected in the final container.
