The image depicts the process of recycling stormwater in a city of Australia.
Overall, this is a linear process with 5 main steps, beginning with the collecting of rain water and ending with the generation of solar energy.
The first step takes place in the harvesting of water after raining, this water will flow through a tube to experience the sorting garbage process. At this step, the impurities in stormwater will be divided into four categories, specifically the first group is plastic and rubbish, the second is small particles, the third is bacteria and viruses, while the final group is molecules and salt. After sorting, these impurities will be cleaned and filtered for recycling.
In the third step, the impurities in collected water can be removed by the use of chlorine, which is a chemical used for cleaning purposes, measuring the amount of 4mg/l. When water is filtered by the chlorine, it will be transferred to the water storage, where it can be used for recycling. The final step is the creation of solar energy, which is used to bring the lights for households in Australia.
