|
7/first filtration
|
Water is filtered through a series of screens to remove fish twigs and leaves and trash
|
|
|
9/second filtration
|
The water trickles down through sand or gravel, which filters out algae, bacteria and some chemicals
|
|
|
10/chorination
|
Chlorine is added to kill the remaining organisms
|
|
|
11/aeration
|
Forcing air through the water releasing gases reducing unpleasant odors or smells
|
|
|
12/Additional treatment
|
Sodium or chlorine may be added to soften hard water
|
|
|
Water distribution
|
Once the water has been treated it goes to the central pumping station and from there it is pumped through out the city
|
|
|
Primary treatment (waste water)
|
Water is held in settling tanks and small particles form on the ground called sludge
|
|
|
Septic Tank
|
, an underground tank containing bacteria as it passes through. Sludge settles at the bottom so it has to be cleaned regularly
|
|
|
|
|
|
|
Secondary treatment
|
Waste water is filtered through a bed of gravel. The gravel is covered with lots of bacteria which breaks down the left over wastes in the sewage.
|
|
|
|
|
|
|
Additional treatment
|
water may be pumped into open pools where sunlight purifies is naturally
|
|
|
leach field
|
the area surrounding the septic tank
