Place these steps in the water treatment process in order from first to last.
1. Flocs are removed from the water.
2. Sand and microbes bind to form flocs.
3. The water flows into a tank to be disinfected.
4. Particles become trapped in filter layers.
To order the steps in the water treatment process from first to last, follow this sequence:
1. Sand and microbes bind to form flocs.
This is the initial step where particles in the water bind together to form larger clumps called flocs.
2. Flocs are removed from the water.
After floc formation, these clumps are removed, often through settling or skimming.
3. Particles become trapped in filter layers.
Then, the water is filtered to remove any remaining solids and impurities.
4. The water flows into a tank to be disinfected.
Finally, the filtered water is disinfected to eliminate harmful pathogens before it is deemed safe for consumption.
This order reflects the logical flow of the water treatment process, starting with the formation of flocs and ending with disinfection. If you have any more questions or need further clarification, feel free to ask!
