Bintaro Lama trip

Hello. Today I am going to tell you about my trip in bintaro lama and the stations I went to about cleaning the water in bintaro lama.

The first station I went to was station 5 where they teach you how to make sure that water is clean. First she gives us these tubes that has a cross at the bottom and fills it up with water. We then look down and you will see the cross is blurry. This means that the water is not clean. There are also other equipment like a thermometer to measure water ph levels.

Next the second station I went to was cleaning the water for taking a bath. They use a filter called a sand filter. How the sand filter works is that water is poured into it and the sand and rocks inside trap nearly all the dirt inside and then water comes out from a pipe into the bath tub with water clean enough to take a bath in.

The final station was station 3 where they clean water to make it potable. First they take a plastic aqua bottle and scrub the whole thing with soap. Next we shake the soap out with water. Then they fill it up with water and put in somewhere where there is sunlight and leave it there for six hours before they can drink it.

That is my trip in bintaro lama.

Water treatment plant trip

Hi. My name is William and I am going to tell you about how the water treatment plan cleans water and the steps to make water potable. You see there are a total of six steps to making it clean and i am going to tell you about each one.

The 1rst is cleaning water is to get the big and small but not microscopic dirt like soda cans or candy or paper for example separated from the water. They do this by first having these bars with a big enough gap in between to take out the big junk in the water. They then scoop up the junk into the garbage can every hour. Water the goes to another filter but this time it takes out the smaller dirt.

The 2nd step is they add chemicals to create flock. The chemicals are limestone,chlorine and one more thing.

The 3rd step is getting the flock to stay on the floor so it does not flow with the water therefore separating the dirt. The reason the flock is on the ground is because more dirt gathers so it becomes heavier.

The 4th step is the water that passed the first three steps go into a sand filter one meter deep. This is used to catch the really small dirt. They also use a special type of sand where most of the grains of sand has the same size.

The 5th step is they add chemical disinfects like chlorine to get rid of all those microscopic dirt particles. They do this so it becomes drinkable.

The final step is they make sure it is clean so they test it out by doing some stuff.

Those are the six steps to make water potable. But there are different ways to make water clean.

Picture on the right clearly shows evaporation since you see water molecules going up.




Picture on right shows condensation since the glass is wet and blurry.










Picture on right shows condensation because there is rain.












Picture on right shows infiltration since part of the ground is muddy.

yesterdays earthquake.

Yesterday there was an earthquake in jakarta. During that same day a snake went into the school and crawled into a hole. The snake must have sensed the earthquake before it happened. Anyway when the earthquake happened I heard it was big and people were freaking out. But in the cafeteria it wasn't so big. When the earthquake hit 38 people died. Bricks must have fallen on most of them since there wasn't a tsunami. But there was a tsunami warning because tsunamis are possible in jakarta. There was definitely no landslide since the terrain is flat. This earthquake must of happened because jakarta is in the ring of fire

Morakot

This is how tall the flood is. As you can see the flood is taller than some trees. The water looks like its flowing pretty slowly.

This must be the after math of the flood.
