I found that pH range in chemical scrubber using NaOH and NaClO for odor control was pointed out by some engineering companies. However, ORP range was rarely mentioned, even though they indicated that it was very important to control ORP.
Could anyone tell me the range of ORP and pH we should...
I'm afraid that there is no bioreactor in our system. But I also considered treating the gas with biofilter or biotrickling. I'm worried that the inlet concentration of non-methane hydrocarbon is too high for bioreactors to treat, and the efficiency could be very low. And I'm wondering that if...
Thanks for all of your replies.
bimr, I'm a little confused about your question. We just treat the gas collected from the sewage storage tank, and I don't think that there is any treatment of the sewage. Do you mean that we should add the water treatment with pure oxygen activated sludge...
We have a project in a petrochemical plant to treat the VOCs from the sewage tank. There are hydrocarbons, including benzene，toluene, and xylene, and H2S in the stream. The inlet concentration of non-methane hydrocarbon is about 6,000 mg/m3, and the air flow rate is 1,700 m3/h. The current...
