Low pH in Clarigester
Low pH in Clarigester
(OP)
Hello All,
I've come across a treatment plant in upstate NY that has a problem with their Clarigester. The pH in the Clarigester dropped from 6.3 to 5.5. There is also a sweet odor emitting from the Clarigester which is indicative of the low pH.
Would anyone know a possible cause along with a fix or solution to this problem?
Thanks!

RE: Low pH in Clarigester
digester process failure are:
• metabolic overloading of the micro-organisms and consequent
pH drop; and
• loss of biomass.
Addition of lime will be necessary to raise the pH to an optimum operating range.

Short of that, experiment by adding lime. Lime is also inexpensive.
