Water treatment plant

We went to a water treatment plant somewhere in Jakarta. What we do there is that we have to clean the water so that we can give the water to the taps in Jakarta.

What we did in the first station is we get the water from the river near us and we remove the garbage from the river which is called Garbage Removal. We take out big trash and little trash like cup noodle cups.

On the second station, we added chlorine to the water to kill the bacteria and we added floc the the water (its a chemical which makes solid objects stick together)

The third station, we had to make the floc sink to the bottom and after that we add chlorine to kill the bacteria again

The fourth station is to make the water go through a 1 meter tell sand so we can get the water clean. Then we add chlorine again!

The last station was to test the water if the water is safe enough to give it to the people who live near the water treatment plant. I learned a lot of things at the plant

5 paragraphs about Bintaro Lama

This is the first time I have ever been to a Kampung. I thought it would be a nice place but it kind of smelled and was dirty. I really felt sorry for the people that was born to live there. We went to 3 different stations around the kampung.

The first station we went to was a very important station and what we did there was we had to look through this bottle full of water and there is a cross at the bottle of the bottle. We had to look through the bottle and see if we could see the cross at the bottom. And if we could see The cross, then the water is clear, but if we cant see the water then it means its dirty.

The second station we went was about the water treatment. What we did was that we learned how to make bath water clean. To do that, we had to have three layers of sand. Then we pour dirty water inside the bottle with three layers. Then the water will come out from the bottom and be clean for having a BATH not drinking.

The third station, we made drinking water. We had to clean the inside of the bottle with soap water. Also we had to clean the cap. Then we had clean water but we cant drink, and washed off the soap that was inside the bottle. Then we had to pour that water inside the bottle and put the bottle on top of the roof. We have to leave it there for 6 hours and if it is cloudy we have to leave it there for 2 days.

After this trip, I really thought about how lucky I am to be living in this life with a water dispenser. I also feel really sorry for the people that live in the kampung. Now I also try to not waste water when I tooth brush.

Infiitration



This is the part of the water cycle when the rain soaks into the earth and goes into the underwater caves like this

Precipitation



This is when you see the sky turning dark and it starts raining. The clouds cant hold the rain and the rain falls on to the earth.

Condensation


This is when the water vapour turns back into liquid and becomes clouds.

evaporation


This is the part when the water turns into water vapour and goes up into the sky

Water cycle















This is when the water
falls to the ground This is the part of the
water cycle when
The little bubbles in the the water soaks into earth

pictrure is the water

which is going up into the air

and turning into water vapour
This is when the water is when you start seeing clouds in the sky and the water vapour turns into water droplets
