Hi everybody, I have to ask for help, once again.
I have to design a process for H2S removal in a break-pressure chamber that is part of a water supply system. I've attached a cross-section of a chamber, with all the pipelines, for you to get a picture of it.
The problem is: the only thing I can change inside the chamber is pipes, which means no additional equipment may be installed. This leads to a conclusion that aeration is the only feasible process. I don't have the data about the H2S concentration, only pH which is 7.85 on average. I am aware that in order for the aeration to be efficient, pH should be around 6, so I guess I would have to include some upstream acid dosage, right?
As for the system itself, I see two possible solutions: upward or downward dispersed flow of water through nozzles (see attached pictures 1 and 2), in order to make as much contact surface between water and air as possible.
Thank you in advance for your opinion, suggestions, advice, etc.
