Water Treatment Plant

In this field trip we got to learn how the water gets clean in the city. The trip to the water treatment plant took for an hour and 10 minutes. I was often asleep in the bus. And finally, we were there, standing in front of a building, but there was more behind it.

Speaking of what's behind it, they are machines or stations which has a job on cleaning water. The first one is called the course and fine filter. They both take out the garbage from a certain river. For what purpose? To make the water clean and to prevent germs from the garbage spread into the freshwater. Sometimes or often, when the machines stop working and, the garbage and dirt keeps on flowing, there's this tool called the power pump (the first thought in my mind that it was kind of a super machine or something) which stops the flowing and prevents them from spreading on the clean water.

The second station is when the water gets added with alum. But it makes you wonder, what is it and what does it do (and trust me, it's not aluminum)? Well, it's kind of hard to explain what alum is but it's some kind of solid particles which makes the dirt stick together. That blob of dirt is called floc.

The third station is like the sequel to the second because it's when the floc slowly settles at the bottom. This station is in a reservoir. The water is more than 6 feet deep and, it looks clean but it's still not potable because there are more processes to do before it's clean. Speaking of more processes, the next one is the fourth station.

The fourth station is when the water is still in the reservoir but this time, there's sand in it. This type of sand is not found in the beach, but it's a special one. It's used to clean the water from the remaining germs (or coli) found. After that, disinfectant was added.

The last but not least station is when the water is transferred to the lab, to test if it's clean or not. The lab also compares the dirty river water to the processed water. The processed water cannot be drinkable but it's good for showers or any other which is not related to drinking.

After that, we went to the control room. Obviously, the control room is in charge of controlling the whole water treatment plant. There were many handles and buttons, and nobody dared to touch a single one to what might happen. Finally, we rested and then, we watched an animated movie which reflects on the water process. It was really hilarious and funny, especially Bondol the eagle. After the movie ( like as usual), we went back to JIS.
