The provided pictures describe the step-by-step process of how rainwater is recycled in a city located in Australia. Overall, the process comprises nine sequential steps, commencing with collecting water from rain and culminating in providing water back for the use of Australians
At the beginning, stormwater is collected in sewes before going through a tube, which leads them to reach the water recycling plant. This factory then extracted water using a purification process with four removal stages. The first phase starts with plastic and trash being removed from the water. Next, small articles are also filtered, followed by the removal of bacteria and viruses in the third stage. The final stage ends with the elimination of molecucles and salt.
After that process, chlorine, with the amount of 4 milligrams per liter, is added to the clear water, which is later stored in a water tank. Finally, water, after finishing the recyling process, is pumped to Australian houses to meet the demands of residents.
