The illustration demonstrates the cycle of rainwater in a city of Australia.
Overall, the process of producing purified water is complex and involves several distinct steps. There are 4 main stages in the sequence, starting with collecting storm liquid and ending with providing water for residential area from liquid storage.
The first two steps involve the transformation of the raw subtance. Initially, rainwater is stored in drains before flowing through a pipe to aqua recycling plant, where this mixture undergoes the thorough purification to remove plastic, rubbish, small particles, bacteria, viruses, molecules and salt, respectively, ready for the next step.
The remaining steps produce clean water for daily life, these contituents from the second phases pass through a pipe to the final filteration with chlorine 4mg/l. Thereafter collecting in a water storage, preparing for further use. Through this repetitive cycle, storm aqua can be recycled and reused.
