The Water Treatment Process

The Water Treatment Process

The water from the Waikato River is not clean so it’s not safe to drink. It’s not clean yet and it’s full of rubbish that makes us sick.

First the water goes through a gigantic filter. A filter is something that has very tiny holes that the liquid and gas can go though but solid can’t go though.

Flocculation is when a chemical is added so all the dirt joins together. The Water is kept in a holding tank where the dirt get’s heavy and sinks to the bottom of the tank.

Filtration is when more chemicals are added to make the water clean. Air is use to get rid of all the small rubbish thats still in the water and it makes it smell good and taste good, this is called ozonation.

Chlorination is when a chemical called chlorine is added. It will destroy all of the bacteria thats still in the water.

Then the water goes to a water tower where all the clean water is kept. Next the clean water that was in the Waikato River goes through a pipe to your tap and is safe to drink.
