How do we Make Water Drinkable

Evan when water is clear, colorless, and odorless, it may not be safe to drink. Water Treatment makes water safe for end-uses such as drinking, cleaning, or farming.

The Water Treatment Process

The water treatment process removes dangerous substances from water. It has many steps:

Pretreatment involves

  • screens may be used to remove rocks, sticks, leaves and other debris;
  • chemicals may be added to control the growth of algae


coagulation This step

  • removes particles in the water
  • Treatment chemicals are added to the water and mixed rapidly in a large basin
  • The chemicals cause small particles to clump together this is called "floc".


During the flocculation

  • the heavy floc settles to the bottom of the water in large tanks.

Clarification

  • Sludge collects at the basin's bottom and is pumped or scraped out
  • Clarification is also sometimes called sedimentation.


Fluoride

  • Is a chemical added to water to reduce tooth decay
  • Fluoride is fed into the water system as either a dry powder or in solution.


Finished water is stored in big tanks. The tanks provide a water reserve to meet the changing water demands of the communities they serve.

Ge water

Ge water is a company that cleanse metals, such as lead, copper, chromium, iron, manganese, mercury, nickel and zinc out of the water. This is the start of the water treatment process.

How does this system effect us and our comunity

If you think about it we don't have a lot of water to drink considering 2.5% of earths water is drinkable. So the impact of this water system on us, has quite a positive outcome because it is keeping our water clean so we have more to drink.

The environmental impact isn't much different, because just like us most of the Earth needs clean water to survive.
