Band 9: The diagram gives information about the process of making carbonated drinks. Summarise the information by selecting and report in the main features, and make comparisons where relevant.

The diagram illustrates the various stages involved in the production of carbonated drinks.

Overall, the process includes five main steps, starting with the purification of raw water and finishing with the packaging and transportation of the final product to stores.

To begin with, raw water is first filtered and then treated with water softeners and chemical additives to make it suitable for use. The second stage involves heating, evaporation, and carbonation. During this step, the clean water is heated in electric heaters, then cooled before carbon dioxide is added to produce the fizzy effect. The carbonated water is then transported through a pipe to the next stage.

In the third phase, the fizzy water is transferred to a mixing tank, where it is combined with colouring, syrup, and flavourings. Once the ingredients are thoroughly mixed, the drink passes through a final filtration stage before moving to the fourth step, where it is filled into bottles or cans. In the final step, these containers are packaged and delivered to supermarkets by truck.
