Water Pollution

Where does it end?

In the forest? No!

In the hole? No!

It ends here at the wastewater treatment plant. Here you can see the plant in Mulllsjö. Unfortunately we were not allowed inside.

The Wastewater Treatment Plant

All the sewage from every house in Mullsjö comes to the wastewater treatment plant where it is purified.

If you look at the picture you can see that the sewage has got to go through five different stages to be purified.

Number one: Here they filter the sewage through a grid to get rid of all big things that people have thrown in their water closets.

Number two: In this section there is a chemical purification. They add iron sulphate that makes the phosphorus to flock, cluster and then it is easy to separate it from the water.

Number three: This is the stage where they use a biological treatment. In the biological section there are a lot of microorganisms that eats everything that is organic in the water.

Number four: Here they let the water run through a current and afterwards the particles falls down to the bottom of the basin and the water runs into the last section.

In the last section you find the same procedure as in number four and after that you can actually drink the water if you want to.

The mud that is left after the purification can be used as a fertilizer by the farmers.

Every community in Sweden must have a Wastewater treatment plant and that is because we do not want to have a lot of different dangerous things that will pollute the environment and maybe run into the ground water and then poison our lakes and our drinking water.

Environment in Sweden

In Sweden we have a lot of problems with buying food and other stuff we don´t need. For example in school we trash a lot of food because we have taken too much and we get full or we don´t like it. That´s not good! We need to learn to take better care of the food we eat. Each year every Swede throws away 56 kilos of food you actually can eat. We also trash 44 kilos we can´t eat, because we keep it in the fridge until it is too old. Now there is a way to recycle the food and process it into biomass fuel. That is why people in many communities separate their food from the other trash.

Another way to be climatsmart is to always make your food from scratch and not buy fabricated food. It`s also important to not buy injected food or food that has been transported far away. It` also important to choose that are made by people that has a fair wage and good working conditions.

In Sweden we buy a lot of stuff we don´t need, like too much clothes, bags, toys and shoes. But a lot of people give away stuff they don´t need to stores who sells it in a better price. Or you just give it to someone that can´t afford new clothes. That is a good way to a better environment.

Air-pollution

One of the big problems in Sweden is air-pollution.

We are 9,5 million people here in Sweden, and totally we have 4,6 million cars. All the air-pollution is destroying our environment.

It isn’t just cars that destroy our land. There are airplanes, lorries and motorcycles too.There are 580 000 lorries and 300 000 motorcycles just in Sweden. We need to do something about it, for example driving electric cars, cycling or travelling by train. Because it is so much better for our environment.

Our cars have catalyzers that increases the chemical rate of reaction without being consumed. And it helps us not to emit as much exhaust. The catalyst converts the harmful substances in the fuel to carbon dioxide and water.
