Water purification system diagram for kids.
Surface water is more often treated rigorously than underground water as it has less contaminants.
This week we worked on a water filtration experiment to teach the kids about water pollution and clean water.
See 200 stem projects for kids we have read a few great books on this topic.
Once the peel is blended put it into a coffee filter.
You may discard the banana or eat it.
Most water is purified and disinfected for human consumption drinking water but water purification may also be carried out for a variety of other purposes including medical pharmacological chemical.

The goal is to produce water fit for specific purposes.
The diagram below shows a basic water treatment process for surface water.
Make a water filter using a fruit peel.
You won t need it for the filter.
Suspended particles get stuck to the chemicals to form floc.
Water purification process by which undesired chemical compounds organic and inorganic materials and biological contaminants are removed from water that process also includes distillation the conversion of a liquid into vapour to condense it back to liquid form and deionization ion removal through the extraction of dissolved salts.
Fruit peels have the ability to absorb bacteria.
Water purification is the process of removing undesirable chemicals biological contaminants suspended solids and gases from water.
Because we won t disinfect our water for this water project and will just be making an example water filtration system it is not safe to drink as this purification process and treatment process we will experiment with will not provide safe and pure water.
Hold the filter over a cup.
