The diagram below illustrates the process of the water filtering. Overall, there are 10 stages, and firstly start with intake screens and ending with faucet. All of process occupy underground.

In the initial stage, intake screens are installed to prevent fish from entering the system. Pumps are used to water’s acting. During the flash mix stage, chemicals are rapidly dispersed throughout the water. Flocculation is using shake chemicals. Settling basin supports bottom under water.

This water reach the chlorine section, then down and come Filter Membrane. It used for keep harmful chemicals, it just allow water cycle. In the part of disinfection, water is cleaned by this device and becoming potable water. Agin used pump, it supports removed water from pipe. In the final stage, faucet helps to control hydrological cycle. It may easily open it or close it.

Task Response

The report identifies the main stages of the water treatment process, but the description of each stage lacks detail and accuracy. There are also some issues with grammar and vocabulary. To improve, focus on providing more specific information about what happens at each stage and use more precise language. Also, ensure that your grammar is accurate and varied. The report falls short of the required 150 words.

Coherence & Cohesion

The report lacks a clear structure and logical flow. The description of each stage feels disjointed, and the connections between them are not well-established. Paragraphing is present but doesn't effectively group related information. To improve coherence, focus on creating smoother transitions between stages and ensuring each paragraph covers a distinct phase of the process. Using cohesive devices (e.g., 'subsequently,' 'following this,' 'afterward') can help guide the reader through the process more effectively.

Lexical Resource

The vocabulary used is limited and sometimes inaccurate. There are instances of imprecise word choice (e.g., 'water's acting,' 'shake chemicals,' 'supports bottom under water'). To enhance lexical resource, try to use more specific and accurate vocabulary related to water treatment processes. Paraphrasing the information from the diagram using a wider range of synonyms would also demonstrate a better command of vocabulary.

Grammatical Range & Accuracy

The report contains numerous grammatical errors, including incorrect verb tenses, subject-verb agreement issues, and awkward phrasing. Sentence structures are often simple and lack complexity. To improve grammatical range and accuracy, focus on using a variety of sentence structures (e.g., complex sentences, passive voice where appropriate) and carefully proofread for errors in grammar and punctuation. Pay attention to verb tense consistency and subject-verb agreement throughout the report.
