Water filtration process

The water filtration process starts like this.
Firstly the water goes through a giant sieve to remove all the litter. 
Then coagulant is added to the water which makes all the dirt sink.
Afterwards the water goes through a membrane filter.This removes germs like giardia. The membrane looks like a piece of string. 
After that the water goes through a carbon tank which gets rid of tastes and smells in the water. 
Finally the water goes through a chlorine tank which kills the remaining germs  
the membrane left behind. 
Remember that if your not sure the water is clean you MUST boil it.
This is the water filtration process.
