We are using biograde 31 microorganism solution which specifically chosen to reduce BOD, COD and TSS.
We managed to bring down the pH to 7.0 using Sulphuric acid. However the pH increased to 8.5 again in one night. We did not let any influent in, and only added microorganism solution.
Our COD, BOD and NH3N value are still high.
I really appreciate anyone who can tell us what's wrong with our SBR tank. It has been one month since the reseeding.

Mr Ong, how often do you have to add biodegrade 31?

not to worrying...most good microbe mixes are self limiting. if it just stays under 9, then its a good set. if it spikes to 9.5 or 10, then you may want to use another set.

this is very common. that's when the microbes grow a lot. in their log phase. the microbes you are using are alkalizing microbes. thus the pH increases.
