Impact of main factors on growth and ability of aerobic thermophilic bacteria for wastewater treatment
In order to study technological properties of aerobic thermophilic bacteria for degrading organic material of selected food wastewater, the thermophilic bacterium Thermus ruber (CCM4212) was adopted. The specific growth conditions and the ability for wastewater treatment of the thermophilic bacteria were studied and results are listed as follows: The optimal growth temperature: is among 50℃ -70℃, and pH: is 7 -9. As waste-water was exploited processing maize dipping water. Tests were carried out on rotary shaker and laboratory bioreactor (effective volume - 4.4 L) according to suggested objectives. Original waste-water was diluted before cultivation started to reach COD about 2000 mg/L -3000 mg/L; rotation speed of the bioreactor impeller was 300 rpm and the air flow rate was 60 L/h. After 12 hours treatment, the COD removal efficiency was about 82.5%.
