After controlling the pH to 7 - 7.5, we managed to reduce the pollutants in our effluent (BOD = 33, NH3N = 11 & COD = 191 - 230).
However, we couldn't further reduce the COD, our local standard limit is 200, we hope it can be reduced to around 100.
Is there any solution to further reduce COD?
The microorganism solution we purchased had no problem degrade COD to less than 100 before.

most of what they call hard cod is actually a lot of phenols and polyphenols. like coffee has a hard time. or germicidal soaps. what you need to try is chem5. instead of buying microbes, you should try a small bioreactor. this way, you won't have to buy microbes again. and it also eliminates sludge and lowers ammonia. take a look at this one minute video.
