The diagram shows how water is processed to make it drinkable. Summarize the information by selecting and reporting the main features and make comparisons where relevant.
The diagram illustrates the process of consumable water. Overall, this process involves multiple stages, starting from taking the water out of the river, followed by processing to providing clean water for houses.
Initially, water is abstracted from a river and stored in a reservoir by transferring an intake pumping station where the next steps begin. In the clarification stage, the water undergoes treatment to remove impurities, making it clearer. This process employs clarification tanks to allow sediments to settle, enhancing the water quality. At this point, water is filtered through a rapid gravity filter, which effectively removes smaller particles while the filtering process ensures that remaining bits of debris are eliminated. After that, the disinfection phase involves the process of removing harmful germs, ensuring the water is safe for consumption.
In the final stage, the clean water is stored in a reservoir before being distributed to homes, schools, and workplaces.
The essay is logically organized with clear progression through the stages of the water treatment process. However, some transitions between stages could be smoother.
Suggestions
- Use more linking words to enhance flow.
- Clarify the sequence of steps more explicitly.
The vocabulary is appropriate and varied, though somewhat limited in range.
The grammatical structures are varied and mostly accurate, with minor errors.
The essay adequately summarizes the diagram and reports the main features, but lacks some detail and comparison.
Suggestions
- Include more details about each stage.
- Make relevant comparisons where applicable.
