Palm oil mill effluent (POME) is a typical organic waste that contains oil and
gerease, high values of chemical oxygen demand (COD), total dissolved solid
(TDS) and total suspended solid (TSS), thus it is highly polluting. The oil
extraction from fresh fruit bunch (FFB) requires a huge amount of water, giving
a rise to volumoneous wastewater, which is called as palm oil mill effluent
(POME). The most common treatment of POME in industrial scale involves
ponding system, which consists of pre-treatment ponds, anaerobic-aerobic ponds
and polishing pond. The anaerobic process requires long hydraulic retention time
(HRT), which is about 60-70 days, whereas other treatment processes need shorter
HRT. It is, therefore, important to have an alternative way to reduce the HRT in
the anaerobic process. Fenton process-based advanced oxidation process (AOP) is
regarded as an effective method for degradation of organic contaminants since it
requires short-period time and is able to completely degrade organic contaminant
into harmless CO2 and water. In this study, two step processes (adsorption and
degradation) were applied for the treatment of POME. The adsoption process was
achived using fly ash activated with microwave radiation of 140 watt power for 3
minutes. The XRD and FTIR were used to identify crystalline phases and
functional groups in the as-activated fly ash, whereas XRF was used to determine
the composition of the ash. The effects of various operating parameters for the
adsorption process such as POME concentration, adsorbent dose, the reaction time
were analysed for the maximum adsorption of POME. The POME quality and
quantity following the treatment process was monitored with the measurement of
COD, TDS and TSS. The result showed that the maximum reduction in COD
concentration was 93.33% obtained at 25 mg adsorbent dose, waste concentration
10:90, birnessite-type manganese oxide catalyst, and H2O2 concentration 3,400
mg/L in 90 minutes. The optimum condition could also reduce the concentrations
of TDS and TSS with decreasing efficiency of 50% and 93%, respectively.
