The image is a flowchart titled 'WATER TREATMENT PROCESS' showing eight stages with icons. The process flows in sequence on the top row from left to right: RAW WATER, followed by PUMPING, then SCREENING, and ending with SEDIMENTATION. An arrow points down from SEDIMENTATION to DISTRIBUTION, which is on the far right of the bottom row. The flow on the bottom row proceeds from right to left, indicated by left-pointing arrows: from DISTRIBUTION to STORAGE, then to DISINFECTION, and finally to FILTRATION.

The diagram provided shows the usual stages of how water is cleaned and filtered before being safe for drinking.

The process of cleaning water, making it safe and drinkable, contains 8 main steps that are the main way many people use, the process starts with getting raw water, then pumping out the raw water, after that comes the water screening, after that the sedimentation.

After the initial stage that contained the first 4 steps, comes the final 4 steps and the final stage of getting filtered water, after sedimentation comes distribution of water, then storing the water, disinfecting the water of germs and bacteria, and lastly filtration. After those 8 steps are done we have clean safe drinking water.

Task Response

The report identifies the main stages of the water treatment process but lacks detail and precision. The description of each stage is very basic, and there's a lack of specific information about what happens at each step. To improve, provide more detail about each stage of the process. Use more precise language to describe the sequence of events and the purpose of each step. Also, avoid repetition and aim for a more concise and coherent summary. The report falls short of the required 150 words.

Coherence & Cohesion

The report presents the information in a generally understandable manner, but the organization could be improved. The description of the stages is somewhat repetitive and lacks clear transitions between them. Consider using more varied cohesive devices to link the stages and improve the flow of information. Paragraphing is basic; consider structuring the report into more distinct paragraphs to separate the initial and final stages more clearly.

Lexical Resource

The vocabulary used is adequate for describing the process, but it is quite basic and lacks sophistication. There is repetition of words like 'water,' 'steps,' and 'process.' Try to incorporate a wider range of vocabulary related to water treatment and purification to enhance the description. For example, instead of 'getting raw water,' you could use 'extracting raw water.'

Grammatical Range & Accuracy

The report contains grammatical errors and phrasing issues that affect clarity. Sentences are often simple and repetitive, which limits the demonstration of grammatical range. Focus on using more complex sentence structures and varied grammatical forms to improve the overall quality of the writing. Pay attention to correct punctuation and sentence construction to enhance accuracy.
