Band 8 IELTS Answer

The picture shown above displays the overall design and the operation procedure of a plain Water Filter to produce clean drinking water. The Water Filter consists of a container equipped with three filtration layers: Gravel, Charcoal, and Sand.

Impure water is channeled into the container, where it passes through these filtration layers sequentially. The Gravel Layer at the bottom level removes or filters out bigger particles from the drinking water. The Charcoal Layer in the middle layer filters out finer impurities and absorbs all the contaminants from the drinking water, while the uppermost layer removes the tiny particles from the drinking water.

Once the water passes through these filtration layers, then the water is completely purified from all the impurities. The filtered water flows from the container to a separate water storage tank through an attached water pipe. This water tank is furnished with a tap, offering access to clean drinking water.

Overall, this simple water filter utilizes natural filtration materials and gravity to effectively purify the drinking water, making it a cost-effective and practical solution for producing clean drinking water.

Band 7.5 IELTS Answer

The diagram shown above displays the construction and working procedure of a Simple Water Filter to produce clean drinking water. The procedure starts by pouring the impure water into a container. This container comprises three different layers of filtering materials successively arranged — Gravel at the bottom layer, which is followed by Charcoal and Sand at the topmost layer.

Each layer of filter primarily serves a specific objective. The Gravel layer extracts larger impurities from the drinking water, the Charcoal filters out finer particles and potential toxins, and the Sand Layer captures the finest debris or impurities from the drinking water.

After passing through these filtration layers, the filtered water flows out of the container through an attached pipe and collects the filtered water in a separate water storage tank. This water tank is filled with pure filtered water, which can be used for drinking.

Overall, this simple filtration system efficiently extracts all the impurities from the drinking water by using natural materials, assuring the production of clean and safe drinking water. Its simplistic design and working method make it practical and accessible for areas with confined resources.

Band 7 IELTS Answer

The image shown above displays the design and functioning of a simple Water Filter system for producing clean drinking water. The Water Filter mainly consists of a large container filled with three filtration layers — Gravel at the bottom layer, Charcoal in the middle layer, and Sand on the uppermost layer.

Unclean water is poured into the filter system, moving across each layer sequentially. The Gravel Layer extracts larger impurities, whereas the Charcoal Layer absorbs small particles and bad smells from the impure water. Ultimately, the Sand Layer offers an extra level of filtration by trapping residual deposits. Once the water is filtered, the clean and pure water then goes into a Water Storage Tank through a drain pipe or outlet pipe. From the water storage tank, the clean water is drawn out for drinking through a tap attached to the tank.

This plain design efficiently extracts all the impurities and contaminants, ensuring safe and clean drinking water. This procedure illustrates an effective and cost-efficient method of water filtration, making it suitable for homes or areas lacking highly advanced filtration systems to get clean and pure drinking water.
