We have been using this biograde 31 all this time. Our previous data shows that it can efficiently decrease COD and BOD. We increased aeration cycle but didn't eliminate anoxic phase as we need it for settling. We are sending our wastewater sample to lab today. Let's see how's the result. Thanks for the info, it's really helpful.
