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 given diagram depicts the process involved in the production of carbonated beverages.

Overall, the manufacturing procedure consists of five main stages, beginning with the purification of water and concluding with the packaging of the final products and delivery to the supermarket.

First of all, the process starts with raw water being passed through a filter to eliminate any impurities. Next, it is treated with chemicals in a water softener to reduce its hardness. In the subsequent stage, the softened water is pumped into an electric heater for evaporation and then cooled through a system of cooling pipes.

Next, the cooled vapour is combined with carbon dioxide to produce carbonated water. In the third stage, this carbonated water is mixed with colouring, syrup, and flavouring to enhance its taste and appearance. The resulting beverage then passes through a second filtration process before being poured into bottles and cans. In the final stage, the filled containers are packaged and transported to supermarkets for sale.
