I have installed a "biofilter" system which extracts H2S from contaminated air by converting it into elemental sulfur. The initial cost is relatively high (approx. $700,000) but the long term operating cost is low. The filter media consists of trays filled with compost like material...

Assuming that you have stabilized the sample if taking to a lab or testing on-site, my experience with the H2S levels at our plant is that it is very erratic. Therefore any one reading is only a snapshot in time at best. I don't know if you have the same type of erratic H2S levels at your plant...

I'll check on your ferric chloride and may followup with you later if that's ok with you. Thanks.

Ginger thanks.

Ginger, Can you tell me what's the approximate changeout for the carbon unit and the material cost?

I am investigating the best method to abate hydrogen sulfide at a wastewater plant. We are looking to install a Biofilter. The Biofilter advantage is that it does not require any hazardous chemicals to operate. We used it sucessfully at one of our lift stations, however it does cost more up...
