Lời giải Task 1:
The picture shows the process of recycling water from rainfall in one city in Australia.
Overall, there are 5 stages in this process, beginning with the collection of rain, and ending with the delivery of clean recycled water to the point where it can be used again.
Initially, rainfall is collected using a system of drains, and the rain – referred to as storm water – passes through a system of pipes to a water recycling plant. At this plant, the water next undergoes treatment in which various substances are removed in 4 steps. Plastics and rubbish are removed first, followed by small particles, then bacteria and viruses and finally molecules and salt.
After the water is cleaned during these steps, it leaves the recycling plant, and chlorine is added at the rate of 4mg per litre. In the last stages, the water is then stored before it is distributed through pipes to the place where it will be used.
