FC: Water Treatment

1: Water treatment is basically water from anywhere that gets cleaned in this big place | What is water treatment? | This is how a water treatment process looks like | the water from the sea can be cleaned. As well as the water we drain down. | Have you ever wondered where our water comes from? Well just so you know, we have been recycling water since there were dinosaurs. That means that we are drinking the same water they did. | In other words, the water that is in the toilet is the same water we drink

2: Well, the water will go through 3 stages of treatment | How does it work? | Primary Treatment | Secondary Treatment | Tertiary Treatment

4: Primary Treatment | Primary treatment is when the water passes through a metal grid | The metal grids help them separate the solids from the liquids | The Metal Grid | It helps block the solids, but the liquid can easily go through

5: The water from before now enters a big tank | While oil or grease will float to the surface. | The solids will sink to the bottom because they are heavier | Then workers will skim off the oil and grease

6: Secondary treatment is when the water from primary treatment enters another tank. | Secondary Treatment | However, this tank is full of bacterias that break down waste

7: When the bacterias break down the waste, they settle to the bottom. | Then the workers will take away the bacterias

8: Tertiary Treatment | In the tertiary stage, they remove chemicals like nitrogen and phosphorus

9: To kill the remaining bacterias, workers would use chlorine, ozone , or ultraviolet radiation.

10: Other things that can pollute water... | Factory waste | Oil | Fertilizers and | Pesticides | When oil is spilled in to water, it can be hard to clean it.

11: For example, in 2010 there was a huge oil spill at the gulf of Mexico. | Gallons of oil was lost so that means the water was really polluted | Many living things had died because of that. Most of us know that oil can be really hard to clean off, so how do you think it was like to practically clean a whole sea?

12: Factory waste can also be really harmful to the water because it is just dumping their waste in the water | For example, it is like our home garbage. We wouldn't want other people to dump their trash on our yard. | Also, once the factory waste piles up, and it becomes impossible to clean, then you would know that we only have a limited supply of water.

13: The reason is that because all living things depend on clean water | If the water id dirty, we all suffer | Long Term effects | Some long term effects is that if the water is polluted, then everything else will be affected as well.

14: Without knowing it is dirty, we drink it | For example, it will cause a chain reaction | First off, dirty polluted water | Then, it comes out of our sink | Next we get terribly sick | And then everybody gets sick from the water. Including animals

15: Also, if one person gets sick from the water and gets a disease, then another person might get sick from that person. | The reason that other person might get sick is because the disease might be contagious | This can also be a long term effect because the disease can keep on spreading until they find a cure.

16: Also, if pesticides or bacterias gets in to our sea, it can kill off all the living things that are there. | For example, it can kill off all the fishes and planktons. Most of us know that planktons give 70% of air. So if they are extinct then it technically means we have less air.

17: Short Term Effects | Even though it is time consuming to get the oil out, it doesn't really last long | Some short term effects is when water gets polluted with oil | But one of the bad thing about oil is that it can contaminate a lot of things such as, animals or plants

18: There isn't really a lot of short term effects because most of them can be long term effects | if one thing happen to our only water source than it will automatically affect us | It is basically long term effects because like i said before

19: How does it affect people? | Waste water treatment can affect people because if it isn't properly treated than it can lead to bad things | For example, there could have been left over bacterias and if we drank the water we could be really ill | However, you can always boil the water just to be sure that it is clean.

20: How can it affect wild life? | Basically, if animals drink the water they can die because of all the pesticides in it | Also, if plants absorbed the polluted water, can also kill the plant | It is like spraying weed remover on the grass. Since the spray has chemicals, it also kills the grass.

21: How safe is this method? | But it can also be dangerous because if something in the plant breaks down, then they can't continue the water treatment | Water treatment can be pretty safe if you do the stages right | However, just to be safe they should double check if the water is waste free

22: It really depends on what you are disposing. | However, if it is waste water than there is because it can harm lots of living things | If it is the clean water, than of course there is no concern in that | There is also a concern in just dumping waste in sea water because it can affect the animal/plants beneath the water

27: "I believe a leaf of grass is no less than the journey work of the stars." | Walt Whitman
