Task 1: The following are two filter systems.Summarize the information by selecting and reporting the main features, and make comparisons where relevant

The diagrams compare two water filter systems, the cross section filter and the simple outdoor filling and storage system.

It can easily be seen that although the two systems follow a similar process, the cross section filter appears to be more effective and space-saving than the other.

The first diagram illustrates a cross section filter system. It is a metal container with the capacity of 20 litres and has three layers of filters. First, the untreated water follows an inlet and goes into the container. It then goes through different filters including sand, tiny stones and pipe holes. After finishing, the filtered water follows an outlet and goes out of the system.

The second diagram shows a simple outdoor filling and storage system. The system includes multiple containers connected to each other. The untreated water is stored in the first one. It then goes through the container filled by sand for filtering and later stored in the storage container, ready for household uses. This system appears to be more convenient for installing at home, however, the quality of water is not ensured.

The diagrams [ 1] compare show two water filter systems, [ 2] the cross section a compact 3-layer filter and the a simple outdoor [ 3] filling filtration and storage system.

It can easily be seen that although the two systems remove impurities from water, [ 4] follow a similar process, the cross section compact filter appears to be more effective and space-saving than the other.

The first diagram illustrates a compact filtration cross section filter system. It is a metal container with the capacity of 200 [ 5] litres and has three layers, an inlet and an outlet. of filters. First, the untreated water follows an flows in through the inlet at the top and goes into the container. It then goes through different filters including sand, down to a bed of tiny stones and then onto a series of pipe holes. After that, finishing, the filtered water follows an flows out through the outlet at the bottom, ready for use. and goes out of the system.

The second diagram shows a simple outdoor filling filtration and storage system. The system includes multiple containers connected to each other. The untreated water is stored in the first one. It then goes through the container A tap controls the flow from that container into another filled by with sand for filtering, after which the water is and later stored in the storage container, stored in a tank ready for household use. This system appears to be more convenient for installing at home, however, the quality of water is not ensured.

[ 1]: There is no comparison; the diagrams just show the systems.

[ 2]: That task was not designed by a native speaker or proficient speaker of English. Look up “cross section” in the dictionary to see what I mean.

[ 3]: Again, that is not your fault, but “filling” is wrong.

[ 4]: The processes are not similar.

[ 5]: Careless mistakes like that one can cost you valuable marks. Always go over your work (at least once) before submitting it to the teacher/examiner.
