Question 2 of 10

2. Not every toilet is connected to a sewer system. Septic tanks and similar inventions are also used. In which country was a worm-based composting toilet developed? Hint

New Zealand

Austria

Australia

Germany

Question 3 of 10

3. Usually, gravity takes the waste materials down the drain and out of the house. How are suction and subsequent clogging issues reduced? Hint

A specially trained plumber regularly cleans the drains from outside the house.

Vent systems bring fresh air to the pipes.

You just need to use aggressive cleaning detergents regularly.

There is no such prevention, thus clogging happens a lot.

Question 4 of 10

4. At the treatment facilities, the waste is usually put in a large pond to settle. Why? Hint

There is just too much waste to deal with, so there is a waiting system.

It is not put anywhere to settle, it is immediately vaccinated with bacteria to clean up the dirt.

Letting it settle allows the system to assess the quality of the waste.

This way, the liquid on top can be pumped into the recycling process while the solid waste may be used as fertilizer.

Question 5 of 10

5. What does a filter system to clean up water look like? Hint

A centrifuge is used to separate pure water from the waste content.

Chemicals are added to the water and bind to the dirt, like in swimming pools.

The water oozes through heavy ground back into the rivers and does not need additional treatment.

The water runs over a filtration medium like carbonized coal, gravel or stones to provide oxygenation.

Question 6 of 10

6. There are more modern ways to filter dirty water. Which of the following is NOT one of those modern techniques? Hint

Membrane Bioreactors (MBR)

Radioactive Recycling Unit (RRU)

Biological Aerated Filters (BAF)

Mechanical Biological Treatment (MBT)

Question 7 of 10

7. Another step in a waste management system is Rotating Biological Contactors. In what country were these contactors first used? Hint

Germany

Denmark

Finland

France

NEXT>

Question 8 of 10

8. Biological treatment is just one of many steps in waste-water processing. Which of the following tertiary treatment methods is designed to detoxify the water further? Hint

Filtration over activated carbon.

Nutrient removal.

Sand filtration.

Lagooning.

9. In small communities, zoos, parks and even industrial sites you may find artificial reed beds and medium sized ponds with sand and water plants. Those are used instead of the standard secondary treatments. What are they called? Hint

Dual Use Wet Units.

Constructed Wetlands.

Aquatic Filter Systems.

They don't actually have names as they double as recreation areas.

Question 10 of 10

10. There are substances that cause a lot of trouble in trying to remove them from the water, and although they are not poisonous as such, harm can still be done if the concentration in the water is too high. Which of the following is not a problem? Hint

Birth Control Pills

Insulin

Antibiotics and Antivirals

Antidepressants

Quiz Answer Key and Fun Facts

1. In modern toilets, the bends collecting toilet water are shaped like certain letters. Can you identify the shapes?

Answer: S,U,J and P

The flush toilet was not invented by one person at a specific time but can be found in separate developments as early as the 26th century BC. The Romans are well known for theirs as well, although they had no fancy shaped bends.

2. Not every toilet is connected to a sewer system. Septic tanks and similar inventions are also used. In which country was a worm-based composting toilet developed?

Answer: New Zealand

There were actually some concerns the poor worms could be negatively affected by having to deal with human waste.

3. Usually, gravity takes the waste materials down the drain and out of the house. How are suction and subsequent clogging issues reduced?

Answer: Vent systems bring fresh air to the pipes.

Usually, those vents exit via your roof, so you need to make sure there are no bird nests or leaves in them if they are not properly covered.

4. At the treatment facilities, the waste is usually put in a large pond to settle. Why?

Answer: This way, the liquid on top can be pumped into the recycling process while the solid waste may be used as fertilizer.

Some of the solid waste may also be used as fuel substitute.

5. What does a filter system to clean up water look like?

Answer: The water runs over a filtration medium like carbonized coal, gravel or stones to provide oxygenation.

Large surfaces are used instead of sand to allow for the forming of bacterial films, fungi and protozoa. This is important because this bio-film is the key agent removing or at least reducing the organic content in the water. It is important that this bio-film does not become too thick or the filter will clog. Worms and insect larvae help to achieve the optimal thickness.

6. There are more modern ways to filter dirty water. Which of the following is NOT one of those modern techniques?

Answer: Radioactive Recycling Unit (RRU)

Radioactivity isn't used in waste management, but radioactive waste can cause major problems during waste water treatment, even in small amounts.

7. Another step in a waste management system is Rotating Biological Contactors. In what country were these contactors first used?

Answer: Germany

A very similar system is used in aquariums. They are also known as Rotating Biological Filters.

8. Biological treatment is just one of many steps in waste-water processing. Which of the following tertiary treatment methods is designed to detoxify the water further?

Answer: Filtration over activated carbon.

Active carbon is known to bind a number of toxins.

Answer: Constructed Wetlands.

Modern zoos use this system more and more. It is an integral part of water processing at my favorite zoo in Gelsenkirchen, Germany, and Chester Zoo in England uses it for the elephants' enclosure.

Answer: Insulin

When we take medication, some of it leaves our bodies unprocessed, ultimately returning back to us as residue in our drinking water. This is one more reason never to flush your unused medication down the toilet. It'll all come back to you!
