The depicted diagram illustrates water filtration procedure utilizing sand filter. It cleanses dirt and particles found in raw water slowly and extracts fresh water ultimately after going through three distinct steps.

The filtration process starts with a comparatively small chamber where the raw water breaks the pressure. That is comparatively smaller in width than the other ones and have a small gap in top of it which is used for the water to penetrate in the next compartment. Undoubtedly, It is the largest portion of the filter as the real filtration happens here. It is comprised of sand and gravel of 60-90 cm and 20-30 cm respectively. Those elements facilitates the water to get rid of filthy elements and thus water gets underdrained. It then proceeds to the next compartment from where filtered water is ready to access.

Overall, the contaminated water goes through three step steady filtration process where sand and gravel do the crucial step of filtration.

Task Response

The report adequately covers the process of water filtration using a slow sand filter, describing the key stages and components involved. However, there could be more specific details included, such as mentioning the specific function of each layer of sand and gravel, to enhance the description and provide a more comprehensive overview. Also, the report could benefit from more precise language and a wider range of vocabulary to improve clarity and sophistication.

Coherence & Cohesion

The report generally presents a clear overview of the water filtration process. However, the organization could be improved for better flow. Consider using more precise transitional phrases to connect the steps in the process more smoothly. For example, instead of simply stating 'It then proceeds,' use phrases like 'Subsequently' or 'Following this stage' to enhance the logical progression. Additionally, ensure each paragraph focuses on a single aspect of the process to improve clarity.

Lexical Resource

The vocabulary used is adequate for describing the process, but there's room for improvement by incorporating more specific and technical terms related to water filtration. For instance, instead of 'cleanses dirt and particles,' you could use terms like 'removes sediment and particulate matter.' Also, vary your word choice to avoid repetition; for example, find alternatives for words like 'compartment' and 'filtration' to demonstrate a broader lexical range.

Grammatical Range & Accuracy

The report contains grammatical errors and phrasing issues that affect clarity. Focus on improving sentence structure and ensuring correct subject-verb agreement. Pay attention to the use of articles (a, an, the) and prepositions, as errors in these areas can confuse the reader. Proofread carefully to catch and correct these mistakes, and consider using a grammar checker to identify areas for improvement.
