Can anyone help me with this please. Please check my reading and if possible I want suggestions for improvements as well

The diagram manifest the manufacture of producing carbonated liquids.Overall, there are five major stages along with ten steps, beginning with the purification of water and finishing with the transportation to retailers. In the first stage - water cleaning, raw water is transferred to a water purifier where it is softened and got rid of harmful chemicals, followed by being pumped directly to electric heaters, the beginning of stage 2 - evaporation and carbonation. After water is heated, its temperature falls in the process of transferring through a cooling pipe to the system in which carbonation happens. Stage 3 starts as soon as the mixing tank is filled with carbonated water, where the process of colouring, adding syrup and flavour goes on. Immediately followed by stage 3 - mixing is stage 4 - filtering and filling when soft water is allocated to bottles. The final stage is packaging, with soft liquids being wrapped up in boxes and transferred to supermarkets and retailers for sale.
