Water Treatment Steps

You can really see the difference between clean water, and dirty water. First of all clean water is tasteless and odorless.... And dirty water is yellow! Plus you can totally smell the dirt that's in there, and it tastes disgusting!!! SO DON'T TRY IT!!!
STEP 1 - Taking the big pieces out of the water
In this step they have these huge things that block the big trash from getting in. Now this step ONLY stops the BIG pieces. When there is a big piece it will get caught in one of the things that dig into the ground and then just stay there. It won't just go away. Someone has to take it out, otherwise it'll just stay in the water, until someone takes it out. It looks really grouse, because all the other stuff just flows into there, and let me tell you, there's some really nasty stuff flowing in there!
STEP 2 - Aeration

Aeration means that they have to poke a hole into the ground so it allows air and water penetrate the surface of the soil. The area is top dressed afterward and sand fills the holes to prevent closure.

STEP 3 - Adding Chemicals


This is an important step of the process. This step is when they have to add all of the chemicals, so that the dirty stuff floats up to the surface.

STEP 4 - Sedimentation


Sedimentation is used to settle out solids in water under the influence of gravity. In sedimentation there are 4 steps.
Step 1 - Is when every particle settles independently.
Step 2 - Is when the particles flocculate as they settle.

Step 3 & 4 - Is when the sludge is thickening.
STEP 5 - Filtration
Filtration is when is passing through a filter.
The trip to the Water Treatment Plant was very cool. I got to learn so many more things about water than I knew at the beginning. In all there are 5 steps.
I thought this trip was really great. Although I must say everyone had sweat dripping down their chins. Sorry that there's not so much of an explanation for filtration. But I think everyone should understand.

This is a good effort, Nora, but steps two and three need more exploration. Step two is not about this process at all, but appears like you did a search and found some information and wrote about it. Also words like 'stuff' have no place in academic writing.
