INFLUENCE OF TEMPERATURE ON THE ACTIVITY OF ANAMMOX GRANULAR BIOMASS - SHORT AND LONG-TERM ASPECT

Abstrakt

The aim of this study was to determine a short-term and long-term effect of temperature on the anammox process rate and determination of temperature coefficients in the Arrhenius and Ratkowski equations. The short-term effects of temperature on the anammox biomass were investigated in batch tests at ten different temperatures in the range of 10-55 ̊C. The maximum rate 1.3 gN (gVSS·d)-1 observed at 40 ̊C. The minimum rate, close to 0 gN (gVSS·d)-1, was observed for the limit values of the analyzed temperature range, (10 and 55 ̊C). The activity tests done at 55 ̊C showed an irreversible loss of the activity due to the biomass lysis. Subsequently, a lab-scale SBR was operated at different temperatures (from 30 to 11 ̊C) to determine the long-term effects. The system was still successfully operated at 15 ̊C but when the temperature was decreased to 11 ̊C, nitrite started to accumulate and the system lost its stability.
