FC: Water/Sewage Treatments | By: Melissa Shan
1: When we finished using the washroom and everything goes to sewage the water gets reused. | Sewage/Water treatments clean the water and the sewage, and make it go through many processes of cleaning, and then the water would serve as tap, or clean toilet water.
2: The water goes through many different processes to clean the water that was already used. Then after it is clean it goes back to your sink and we use it again.
3: A real life example is the primary, secondary and Tertiary treatments.
4: Primary Treatment is using the floating method. The tanks let the oils and grease float to the top and then they skim the layer off.
5: Secondary Treatment is when chemical put the wastes (like human waste, bacteria, and germs) into floc which is insoluble. Then the floc sinks down to the bottom of the tank and while the clean water moves on to the next treatment the waste goes the sludge treatments
6: Tertiary Treatment is when it is sprayed with chemicals to clean out any more bacteria and wastes in the water. | they put the water through chlorine and ozone (Disinfection) cleaning off viruses, germs and fungi.
7: Long/Short term effects | There is no Short term effects for misshaped sewage treatments, but however the Long term affects are very serious. There could be ~Poisoning ~Fatal Illnesses or Disease ~Death ~Less oxygen in the water because the wastes takes most of the oxygen ~Dead habitants in the water (Fishes. etc)
8: If we drink un-cleaned water, we get sick or get transmitted diseases from the water's bacteria. | The wildlife aquatic species like fish would die because of the lack of oxygen because of the decayed and debris use up the oxygen. | Kids suffering from waterborne disease.
9: This method is very safe. It also helps the environment's species by providing clean and fresh water to live in. It also cleans out everything we can be sick from.
10: If you dispose un-clean water without putting through the sewage/water treatment, it would cause all of the long term effects, including polluting the water. In fact, if you dump dirty water every time the fish and habitants will start to die and may cause extinction or lack of seafood
11: A real life event that was associated with this issue is Walkerton, Ontario in May 2000, when farm waste ran into and easily contaminated well supplying the water, 2500 got affected by E.Coli infection from the water and 7 people died
