“…According to Annop et al [201], prolonged filtration-relaxation under anaerobic condition expedites the formation of biofilm on the membrane. This is because of the massive transportations of foulants towards the membrane surface, and this often resulted in high polarization [174,202,203]. This is in line with the report of the study conducted at high flux (35 Lm −2 h −1 ) with a specified aeration demand (0.25 Nm 3 /m 2 h) by [117].…”

Over the years, different types of alternative technologies have been developed and used for palm oil mill effluent (POME) treatment. Specifically, membrane bioreactor (MBR) has been employed to relegate pollutants contained in POME under different operating conditions, and the technology was found to be promising. The major challenge impeding the wider application of this technology is membrane fouling, which usually attracts high operating energy and running cost. In this regard, novel methods of mitigating membrane fouling through the treatment processes have been developed. Therefore, this review article specifically focuses on the recent treatment processes of POME using MBR, with particular emphasis on innovative processes conditions such as aerobic, anaerobic, and hybrid processing as well as their performance in relation to fouling minimization. Furthermore, the effects of sonication and thermophilic and mesophilic conditions on membrane blockage were critically reviewed. The types of foulants and fouling mechanism as influenced by different operating conditions were also analyzed censoriously.

“…Therefore, interest in lower-cost alternatives to commercially available activated carbon that would still provide safe and economical methods of removing dyes from contaminated water has increased. For this reason, low-cost by-products of agriculture that able to act as an adsorbent have been recognized as a sustainable solution for wastewater treatment that minimizes waste, recovery, and reuse 6 , 15 , 17 , 21 – 24 , 38 . To support the sustainable option for removing dyes, PAC has been synthesized from rubber seed (RS) and its shell (RSS).…”

In this study, two biomass-based adsorbents were used as new precursors for optimizing synthesis conditions of a cost-effective powdered activated carbon (PAC). The PAC removed dyes from an aqueous solution using carbonization and activation by KOH, NaOH, and H2SO4. The optimum synthesis, activation temperature, time and impregnation ratio, removal rate, and uptake capacity were determined. The optimum PAC was analyzed and characterized using Fourier-transform infrared spectroscopy (FTIR), x-ray diffraction (XRD), a field emission scanning electron microscope (FESEM), Zeta potential, and Raman spectroscopy. Morphological studies showed single-layered planes with highly porous surfaces, especially PAC activated by NaOH and H2SO4. The results showed that the experimental data were well-fitted with a pseudo-second-order model. Based on Langmuir isotherm, the maximum adsorption capacity for removing methylene blue (MB) was 769.23 mg g−1 and 458.43 mg g−1 for congo red (CR). Based on the isotherm models, more than one mechanism was involved in the adsorption process, monolayer for the anionic dye and multilayer for the cationic dye. Elovich and intraparticle diffusion kinetic models showed that rubber seed shells (RSS) has higher α values with a greater tendency to adsorb dyes compared to rubber seed (RS). A thermodynamic study showed that both dyes’ adsorption process was spontaneous and exothermic due to the negative values of the enthalpy (ΔH) and Gibbs free energy (ΔG). The change in removal efficiency of adsorbent for regeneration study was observed in the seventh cycles, with a 3% decline in the CR and 2% decline in MB removal performance. This study showed that the presence of functional groups and active sites on the produced adsorbent (hydroxyl, alkoxy, carboxyl, and π − π) contributed to its considerable affinity for adsorption in dye removal. Therefore, the optimum PAC can serve as efficient and cost-effective adsorbents to remove dyes from industrial wastewater.

Palm oil mill effluent (POME) is a liquid waste by product of fresh fruit bunches processing (FFB) in palm oil factory (POF). POME contains oil residue of 0.7% (from treated FFB). The purpose of this study was to convert oil residue of POME into biogasolin with the help of ultrasonic irradiation and catalytic cracking. The convertion was performed by reacting oil residue of POME with methanol in an esterification and transesterification reaction with the aid of ultrasonic irradiation. The reaction product was further reacted in the catalytic cracking reaction using zeolite-based catalysts (Ni/HZa and Mo-Ni/HZa). The overall reaction results were characterized using GCMS to determine the constituent components. The components found using Mo-Ni/HZa catalyst were 51.22% biogasoline and other products of kerosene and diesel as well as long chain methyl ester components, whereas using Ni/HZa catalyst was found a component equivalent to diesel at 2.44%.
