| Abstract | The research reported herein was conducted to study the sources and characteristics of
brewery wastewater and to find a possible waste treatment and also evaluate the existing
wastewater treatment at the brewery factory. Major sources of wastewaters were wash water
from various processes in the brewery. The patterns of the wastewater flows were found to be
highly variable on both an hourly and daily basis and the quality of wastewater varied as well.
The wastewater from all process had high COD concentration (more than 900 mg/l) at least
and the pattern of flow rate was also very high variable, which is impossible to be by passed
to the recipient directly. Therefore no stream segregation is suggested to be treated
individually. Some waste sources could be managed separately and disposed as solid waste
for by-products.
The existing BIOLAK system could also be evaluated that it can be effective for substrate
removal if the COD influence is less than 1400 mg/land load less than 400 kg/d. Likewise for
the suspended solid and NH4-N less than 500 mg/l and 30 mg/l respectively. The study also
indicated that the removal efficiency of the plant were high when the loading criteria is
around 0.13 to 0.2 kgCOD/kgMLSS The nutrient supply to the system is not always sufficient
because high efficiency of the plant, when the NH4-N is around 20 to 35 mg/l and low
efficiency when the NH4-N is below 20 mg/I was found.
The anaerobic pre-treatment can be applied at the brewery in the future if the factory is to
increase its products. From this study, the derived from published results anaerobic treatment
is very promising as a pretreatment, as an evidence, a practical investigation in place was
found that the organic removal efficiency and suspended solid were up to 90 % and 80 %
respectively. |
