KEMAMPUAN ALKALINITAS KAPASITAS PENYANGGAN (BUFFER CAPACITY) DALAM SISTEM ANAEROBIK FIXED BED

Abstract

In the process of decomposition of the organic matter with the anaerobic
system was learnt that the methane forming bacteria of was very
sensitive to the level of the acidity in other words very sensitive with the
low pH. There are by two big groups the bacteria that was active in this
system. These two bacteria group had the duplication capacity that
was very different that is 3 hours during the acid forming bacteria of and
3 days for the methane forming bacteria. The alkalinity in the reactor
with the certain concentration between 1000 – 5000 mg/l could support
the pH continue to in the neutral condition when the decline in the pH
happened so as the balance of the process could on the whole stay
proceeding normally.
It was observed that achieving the pH 3 in the feeding, the concentration
of the alkalinity descended through to 500 mg/l this was the lowered
condition and the process of decomposition of the organic matter was
disrupted. When being left alone then the system will stop completely
because of the methane forming bacteria was inhibited.
