There would be close to none clean water in the natural water cycle. ]]> 2018-10-05 16:02:21 UTC https://padlet.com/weinsmad000/2uer3nh29use/wish/289698074 Add your picture here weinsmad000 https://padlet.com/weinsmad000/2uer3nh29use/wish/289698075 2018-10-05 16:02:21 UTC https://padlet.com/weinsmad000/2uer3nh29use/wish/289698075 What is removed after the disinfection stage weinsmad000 https://padlet.com/weinsmad000/2uer3nh29use/wish/289698076 Micro organisms, such as germs from human waste. ]]> 2018-10-05 16:02:21 UTC https://padlet.com/weinsmad000/2uer3nh29use/wish/289698076 Why is disinfection necessary? weinsmad000 https://padlet.com/weinsmad000/2uer3nh29use/wish/289698077 Although the water may look clear at this stage, it may still contain micro organisms that we can't see such as germs that we need to remove to protect humans and animals. ]]> 2018-10-05 16:02:21 UTC https://padlet.com/weinsmad000/2uer3nh29use/wish/289698077 Add your picture here weinsmad000 https://padlet.com/weinsmad000/2uer3nh29use/wish/289698079 I lost my picture for this one somehow :/ At this point there were very few solids left in the waste, and the color was a medium-shade of orange. It was really close to how the disinfection one looked since we already got so many of the solids out. ]]> 2018-10-05 16:02:21 UTC https://padlet.com/weinsmad000/2uer3nh29use/wish/289698079 What is the secondary sludge weinsmad000 https://padlet.com/weinsmad000/2uer3nh29use/wish/289698080 The organisms that feed off of the nutrients in the bioreactors along with the germs from human waste, which form clumps and a brown sludge]]> 2018-10-05 16:02:21 UTC https://padlet.com/weinsmad000/2uer3nh29use/wish/289698080 What happens to the secondary sludge and why? weinsmad000 https://padlet.com/weinsmad000/2uer3nh29use/wish/289698081 It is dried to kill the germs, and then used as a fertilizer so that compost can be made. It must be treated first though, so that the toxic bacteria from human waste doesn't pose a threat to humans and the environment. ]]> 2018-10-05 16:02:21 UTC https://padlet.com/weinsmad000/2uer3nh29use/wish/289698081 Add your picture here weinsmad000 https://padlet.com/weinsmad000/2uer3nh29use/wish/289698082 2018-10-05 16:02:21 UTC https://padlet.com/weinsmad000/2uer3nh29use/wish/289698082 What wastes are still present in the water weinsmad000 https://padlet.com/weinsmad000/2uer3nh29use/wish/289698083 Carbon from human waste, nitrogen from human urine, and phosphourous from soap. ]]> 2018-10-05 16:02:21 UTC https://padlet.com/weinsmad000/2uer3nh29use/wish/289698083 What does the "bioreactor" represent? weinsmad000 https://padlet.com/weinsmad000/2uer3nh29use/wish/289698085 The gases that are produced from the carbon, nitrogen, and phosphourous elements.]]> 2018-10-05 16:02:21 UTC https://padlet.com/weinsmad000/2uer3nh29use/wish/289698085 What wastes are removed in the bioreactor weinsmad000 https://padlet.com/weinsmad000/2uer3nh29use/wish/289698087 Elements of human waste, urine, and soaps.

This occurs because the waste water is flowing very slowly at this point which lets all of this sludge sink. ]]> 2018-10-05 16:02:21 UTC https://padlet.com/weinsmad000/2uer3nh29use/wish/289698092 What happens to the oils? weinsmad000 https://padlet.com/weinsmad000/2uer3nh29use/wish/289698093 The oils float to the surface, they are then scraped off with a scraper and buried in a landfill.]]> 2018-10-05 16:02:21 UTC https://padlet.com/weinsmad000/2uer3nh29use/wish/289698093 What makes up the primary sludge? weinsmad000 https://padlet.com/weinsmad000/2uer3nh29use/wish/289698097 The primary sludge is made up of untreated, solid human waste and germs. ]]> 2018-10-05 16:02:21 UTC https://padlet.com/weinsmad000/2uer3nh29use/wish/289698097 Add your picture here weinsmad000 https://padlet.com/weinsmad000/2uer3nh29use/wish/289698099 2018-10-05 16:02:21 UTC https://padlet.com/weinsmad000/2uer3nh29use/wish/289698099 Why is this step needed?

Also, grit can cause damage to pumps and tanks so that is another reason why it is needed to be removed. The grit was removed, which is composed of small stones, representing sand, soil, and stones. ]]> 2018-10-05 16:02:21 UTC https://padlet.com/weinsmad000/2uer3nh29use/wish/289698100 What happens to the grit? weinsmad000 https://padlet.com/weinsmad000/2uer3nh29use/wish/289698102 It is taken to a landfill and buried.]]> 2018-10-05 16:02:21 UTC https://padlet.com/weinsmad000/2uer3nh29use/wish/289698102 Add your picture here weinsmad000 https://padlet.com/weinsmad000/2uer3nh29use/wish/289698103 2018-10-05 16:02:21 UTC https://padlet.com/weinsmad000/2uer3nh29use/wish/289698103 Why is this step needed? What was removed? product and what it represents weinsmad000 https://padlet.com/weinsmad000/2uer3nh29use/wish/289698106 This step is needed because it removes the larger objects to 1) already remove a good chunk of the larger contaminants and 2) Get them out of the way so they don't damage all of the pumps and tanks involved in the rest of the treatment process. In this process we removed the leaves and rocks, which represents grits and fine human solids/waste, and the larger pieces like tampons, condoms, and other things that are flushed but shouldn't be.]]> 2018-10-05 16:02:21 UTC https://padlet.com/weinsmad000/2uer3nh29use/wish/289698106 What happens to all the screening? weinsmad000 https://padlet.com/weinsmad000/2uer3nh29use/wish/289698107 They are removed and buried in a landfill.

There is also sugar, tea, pieces of the teabag itself, and cooking oil. The sugar and tea mixed right in with the water, and the other solids were either nonpolar (the oil) and counteracted the water, or floated/sunk (the rocks and leaves).]]> 2018-10-05 16:02:21 UTC https://padlet.com/weinsmad000/2uer3nh29use/wish/289698110
