“…. The best fit for MOSF, based on the linearity ( R 2 ), was for the intra‐particle diffusion model, indicating that intra‐particle diffusion controls the whole process of adsorption . With chitosan, higher linearity was attained for the pseudo‐second order equation; it was then determined that the rate‐controlling step was chemisorption .…”

The aim of this contribution is to provide a comprehensive comparison between chitosan and Moringa oleifera seed flour (MOSF) as coagulant-flocculants. MOSF was obtained as a byproduct in a biodiesel process. Turbidity and heavy metal ion removal, using both ecofriendly materials, was assessed. Jar tests were performed on samples taken from river water, agricultural wastewater, and mixed wastewater (contaminated with agricultural and urban residues). Bioflocculant dosages within the range of 0.005-20 mg L À1 were tested. Irrespective of the initial turbidity, the optimal dosage of chitosan and MOSF for decreasing turbidity in river water was 1 and 5 mg L À1 , respectively. Furthermore, from river water, Pb removal up to 95% was achieved irrespective of the bioflocculant; for Mn removal, MOSF performed better than chitosan, with the adsorbent trapping close to 90% of this metal. MOSF decreased turbidity levels and heavy metal content (Mn and Pb) to under the permissible limits (Mexican environmental regulation for potable water, NOM-127-SSA1-1994). Additionally, kinetic data were fitted to kinetic models of adsorption for the pollutants. For agricultural wastewater, a chitosan dosage of 10 mg L À1 reduced turbidity to 5-10 nephelometric turbidity units (NTU), and a MOSF dosage of 10 mg L À1 decreased the turbidity to values lower than 5 NTU. For the mixed wastewater, chitosan achieved a high turbidity removal, while MOSF was not suitable.

“…Membrane fouling could cause gross deterioration of the system performance in terms of filtration and operational energy utilization, as highlighted earlier. Therefore, the need to control the fouling is indispensable and this justified the previous studies reported on this critical area [67,110,161,[255][256][257][258]. The efforts devoted by the researchers have yielded some improvements such as membrane fouling control strategies and filtration.…”

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.

“…With this, the permissible BOD discharge limit of POME has recently been reduced further from 100 mg/L to 20 mg/L [12]. Numerous alternative treatment techniques for POME have been studied by researchers, including aerobic submerged membrane bioreactor [13], anaerobic/aerobic bioreactor [14], activated carbon adsorption and ultrasound cavitation [15,16], membrane process [17,18], advanced oxidation process [19], photocatalytic degradation [9] and electrocoagulation [7]. However, most of these methods are either costly or triggering hostile effects to the environment.…”

It is inevitable that the manufacturing process of palm oil is accompanied by the generation of a massive amount of high strength wastewater, namely palm oil mill effluent (POME), which could pose serious threat to the aquatic environment. POME which contains high organic compounds originating from biodegradable materials causes water pollution if not properly managed. Palm oil industries are facing the challenges to make ends meet in the aspects of natural assurance, financial reasonability and development sustainability. It is therefore crucial to seek a practical solution to achieve the goal of environmental protection while continuing the economic sustainability. Phytoremediation has been proven as a potential method for removal or degradation of various hazardous contaminants. However, research on phytoremediation of POME using Eichhornia crassipes (E. crassipes) is still limited. This study aims to determine the feasibility of applying phytoremediation technique using E. crassipes for POME treatment. The effects of pH, plant:POME ratio and retention time on the biochemical oxygen demand (BOD), chemical oxygen demand (COD) and total suspended solid (TSS) of POME were investigated. The highest BOD removal of 92.6% was achieved after 21 days retention time at pH 4 with plant:POME ratio of 1:20 kg/L. The highest COD removal of 20.7% was achieved after 14 days retention time at pH 6 with plant:POME ratio of 1:20 kg/L. Phytoremediation using E. crassipes was shown to be a promising eco-friendly technique for POME treatment, and is therefore recommended as a good alternative treatment solution for this industrial effluent.
