The rapid development of Crude Palm Oil (CPO) production has led to an increase in the production of Palm Oil Mill Effluent (POME) as well. POME will cause problems in the environment because contains high contaminants. This study aims to investigate the effect of the coagulant Polyaluminium Chloride (PAC) variations and the membrane’s operating pressure on the POME treatment process using the nanofiltration membrane (NF) with the coagulation-flocculation process as pre-treatment. The PAC was used in the coagulation-flocculation process with variations in concentration (5.0; 5.5; 6.0; 6.5; 7.0 g/L). The process was completed by a rapid stirring of 200 rpm for 5 minutes, followed with slow stirring at 60 rpm for 15 minutes and settling time for 30 minutes. The process of membrane nanofiltration was carried out for 60 minutes with variations in operating pressure (8.0; 9.0; and 10 bars). In each treatment process, effluent quality testing was carried out with Biochemical Oxygen Demand (BOD5), Chemical Oxygen Demand (COD), Total Suspended Solid (TSS) and oil/fat as parameters. In addition, an analysis of permeate fluxes and rejection of NF membrane was also carried out. The results of the analysis suggested that the best coagulant doses are 6.0 g/L with the reduction percentage of BOD, COD, TSS and oil/fat at 78.85%; 68.57%; 92.77% and 92.31% respectively. The highest percentage of NF membrane rejection was found at a pressure of 10 bar, which is equal to 94.71%; 94.86%; 97.92% and 95% respectively for BOD, COD, TSS and oil/fat with a flux value of 7.16 L/m2.hours.

Typically, palm oil mill industries use conventional anaerobic ponds for treatment of palm oil mill effluent (POME). But, this method alone cannot produce effluent discharge to an allowable limits set by the authorities. This study aimed to investigate further treatment of anaerobically digested POME (COD = 682±14 mgL-1, TSS = 29±7 mgL-1 and turbidity = 106±3 NTU) by coagulation-flocculation process. Alum, an industrial-accepted coagulant and OC 100 and PC 100W as two industrial-based polymeric flocculants were used in coagulation-flocculation process. Results indicate coagulation process in its optimum conditions (pH = 6, alum dosage = 1800 mgL-1, rapid mixing = 5 min, and slow mixing = 20 min) reduces the COD, TSS and turbidity by 59%, 80% and 86%, respectively. Flocculants OC 100 and PC 100W caused further reduction of TSS (85–88%) and turbidity (97–98%). By application of post treatment, the POME characteristics reached to an acceptable discharge level enforced by Malaysian department of environment (DOE).

The aim of the current study is to evaluate the effectiveness of combined persulphate with hydrogen peroxide (S2O82−/H2O2) oxidation as a post-treatment of biologically treated palm oil mill effluent (POME) for the first time in the literature. The removal efficiencies of chemical oxygen demand (COD), ammoniacal nitrogen (NH3-N), and suspended solids (SS) were 36.8%, 47.6%, and 90.6%, respectively, by S2O82− oxidation alone under certain operation conditions (i.e., S2O82− = 0.82 g, pH 11, and contact time 20 min). Nevertheless, the combined process (S2O82−/H2O2) achieved 75.8% and 87.1% removals of NH3-N and SS, respectively, under 2.45/1.63 g/g H2O2/S2O82−, pH 11, and 20 min oxidation. Moreover, 56.9% of COD was removed at pH 8.4.

Abstract The application of microalgae in wastewater treatment has attracted the attention of researchers since a few decades ago. Palm oil industry is one of the lucrative main exporting industry in Malaysia which has drawn the attention of researchers in mitigating the polluting impacts caused by the palm oil mill effluent (POME) released from the oil palm processing. In this study, the growth of the green algae Chlorella vulgaris and Chlamydomonas reinhardtii in the pre-treated POME was studied for 7 continuous days. The number of microalgae cells, chlorophylls and carotenoids contents were monitored throughout the cultivation period. The potential of both strains of microalgae as the water polisher for post-treatment of POME was investigated as well. The findings revealed that both microalgae showed lag phase at the beginning of cultivation and grew exponentially later. When monitoring the chlorophyll content, chlorophyll a and chlorophyll b played a role in photosynthesis when the microalgae detected environmental changes. The carotenoids in the microalgae acted as the accessory pigments which assisted in light harvesting under poor light condition and as the antioxidant protecting the cells when there was excess light. C. vulgaris was able to remove 98.1 % of phosphate and 53.1 % of ammoniacal nitrogen while C. reinhardtii removed 90.1 % and 37.3 %, respectively. This study indicated that two microalgae species have a high potential to be integrated in the post-treatment for POME.
