| Abstract | This study was conducted to improve the existing effluent treatment system to meet Thailand
industrial effluent standards by minimizing wastewater in the processing of oil palm fruit. This
study was focused in a medium scale palm oil mill, located in Ao Luk, Thailand. Currently,
the capacity of the mill is 30 tons FFB/h. The factory is using 27 m3 /h of fresh water in the
process and producing 39 m3
/h of wastewater. Scrubber unit is producing 30m3
/h wastewater
and consuming 74 m /h to trap the solid particulate from the flue gas. The color of effluent
from the mill is 840 ADMI and 250 mg/L alum dose is optimum to remove the color to the
level of no objection.
In this study, boiler modification to control air pollution as well as minimize scrubber
wastewater, automation of sterilization operation were identified as the potential options for
wastewater minimization. For improvement of effluent treatment plant, dilution of wastewater
by recycling effluent, mixing scrubber and process wastewater to adjust pH, deep anaerobic
ponds, training for the operator and continuous monitoring of treatment system were potential
options to reach effluent standards. |
