Put the dialogue in the correct order.Ułóż dialog w odpowiedniej kolejności.
- Ok. So now we know that we will make use of aeration and filtration. What processes and devices are you suggesting?
- No. In my opinion, that’s the best solution.
- For such an extraction and not too big water supply, ozonisation would be the best choice.
- Are there any other suggestions?
- In what form is iron, since it influences the method of its removal?
- I think the best option will be ionites.
- We still have a problem of water hardness.
- According to the study, it is in a form of iron hydrogen carbonate.
- Ok. In this case we still need to think about disinfection. Although the water doesn’t contain any bacteria, keeping it in a water supply for a long time might contribute to bacterial growth. What are the suggestions?
- For certain, aerators will be used, as they will be helpful in the process of carbon dioxide removal since its concentration isn’t too high. Aerators will also oxidate water, in which iron will precipitate as iron dioxide. Next, it will be stopped on closed filters. This process also removes manganese.
- We have a proposition to submit a tender: to make a project of a station for the treatment of underground water for Korzecin municipality. Most importantly, the water is hard, ironed, manganese level is exceeded, and it is acidified with carbon dioxide.
