Polyacrylamide-induced coagulation process removing suspended solids from palm oil mill effluent

High consumption and production of palm oil have led to the massive generation of palm oil mill effluent (POME). This study was intended to reduce the total suspended solids (TSS), turbidity and colour using hybrid coagulation-ultrafiltration process. POME was pre-treated with coagulation process using polyaluminium chloride (PAC) and optimization of operating condition for coagulation process was performed. The coagulation results revealed that optimum pH, dosage of coagulant and rapid mixing speed were pH 4, 600 mg/L and 200 rpm, respectively. It achieved the highest percent reduction of TSS, turbidity and colour with 99.74%, 94.44% and 94.60%, respectively. Ultrafiltration (UF) membrane was fabricated using polyethersulfone (PES), polyvinylpyrrolidone (PVP) and titanium dioxide (TiO2) nanoparticle. Different concentrations ranging from zero and 1.0 wt% of TiO2 nanoparticles were added into the dope solution. The characterization studies of UF membranes confirmed that higher concentration of TiO2 provided higher pure water permeability and more porous structure in the UF membranes. The amount of TiO2 in membrane only affected the permeate flux but had no obvious effects on the reduction of TSS, turbidity and colour. The optimum transmembrane pressure was found to be 3 bar, resulting in the greatest reduction of TSS, turbidity and colour.

The aim of this research is to evaluate the feasibility of the fibrous media for removal of total suspended solid and oil grease from palm oil mill effluent (POME). Wet lay-up method was adopted for filter fabrication where empty fruit bunches (EFB) were matted together with chitosan in non-woven manner. Chitosan-filled filter media were tested for their ability to reduce Total Suspended Solids (TSS) and Oil & Grease (O&G) from palm oil mill effluent. Filtration process results indicated that chitosan-filled filter media filtration only removed up to 28.14% of TSS and 29.86% of O&G.

Flocculation Process

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.

Artificial Neural

In the present research, local rambutan seed extract was used as a bio-coagulant for the treatment of palm oil mill effluent (POME). Jar test experiments were conducted to find the optimal operating conditions for the removal of turbidity and total suspended solids from POME. At an optimal pH of 3, bio-coagulant dosage of 600 mg/L and room temperature of 28⁰C, an impressive removal of 65% of total suspended solids and 79% of turbidity was achieved. Along with this, a Feedforward Artificial Neural Network (FANN) was used to model the coagulation mechanism. Three different training algorithms were tested on the FANN, namely the Lavenberg-Marquardt, Bayesian Regularization and Scaled Conjugate Gradient methods. The best training algorithm was found to be Bayesian Regularization, based on the fact that it was in closer agreement with the experiment results and gave very low error percentage. The results of this study suggest that rambutan seeds have potential in being used as a bio-coagulant for POME treatment. Treatment efficiencies were reasonably high, and less sludge was produced using this natural treatment method, thus deemed to be more economical and environmentally friendly.
