I'VE SOLVED IT! Excuse the pun :)
Thanks for your help people.
I found out the pH of the water supply is HARD. It should be sufficient to dissolve the H2S simply with aeration. Thus zero maintenence :)
Thanks for efforts thus far. You would have seen theres not much on google for it. I've already spoken to John Caroll at AQualibrium. He simply advised using NaOH to control the solubility - which sought of disregards what I'm trying to do. I'll write to him again and invite him to join this thread.
The contamination levels of the air are variable between 5-100000 ppb. The body of water may be considered as infinite as far as water contamination issues matter. The problem presents such that the H2S-air may only make one pass through the water and this feature is the limiting concern. Thus...
Yes I'm trying to do the exact reverse - put the H2S back in the water. I'm hoping that since the water has zero H2S to start and since the H2S conc. in the air is so low, that I may accomplish this. But while bubbling the air through the water will disolve SOME of the H2S the fugacity will...
Activated carbon filter would do the trick BUT I can't have any maintenence rewuirments. The body of water thats to be impregnated can be replenished periodically such that the filter/catalyst/aerator will be momentarily exposed to atmosphere. I'm hoping that simply this periodic fresh...
I need to extract H2S(g) from polluted air source into drinking water oxidising the H2S in process. Contaminated air at 20-100ppm H2S. Resulting surfacing air must be void of odour.
Suggestions for aerater-filter-catalyst?
