“…For example, cellulose biopolymers and derivatives are being adapted for water filtration by fabricating them into ultrafiltration, nanofiltration, and osmotic membranes. Notably, these membranes are being used in the removal of contaminants such as dyes [6,8,12,40], microorganisms [8,134], heavy metals and salts [6,8,135], pharmaceuticals [8,38], pesticides, and oil/grease [8,40]. However, more work still needs to be done to improve the characteristics and performance properties of biopolymers [10].…”

“…Notably, the ligands containing these functional groups can enhance the selectivity of modified membranes and significantly participate in the adsorption-desorption processes of contaminants [12]. The hydroxyl group on the cellulose backbone also coordinates with charged pollutants such as salts and heavy metals via electrostatic attraction, ion exchange, van der Waals forces, and hydrogen bonding [135].…”

Herein, this paper details a comprehensive review on the biopolymeric membrane applications in micropollutants’ removal from wastewater. As such, the implications of utilising non-biodegradable membrane materials are outlined. In comparison, considerations on the concept of utilising nanostructured biodegradable polymeric membranes are also outlined. Such biodegradable polymers under considerations include biopolymers-derived cellulose and carrageenan. The advantages of these biopolymer materials include renewability, biocompatibility, biodegradability, and cost-effectiveness when compared to non-biodegradable polymers. The modifications of the biopolymeric membranes were also deliberated in detail. This included the utilisation of cellulose as matrix support for nanomaterials. Furthermore, attention towards the recent advances on using nanofillers towards the stabilisation and enhancement of biopolymeric membrane performances towards organic contaminants removal. It was noted that most of the biopolymeric membrane applications focused on organic dyes (methyl blue, Congo red, azo dyes), crude oil, hexane, and pharmaceutical chemicals such as tetracycline. However, more studies should be dedicated towards emerging pollutants such as micropollutants. The biopolymeric membrane performances such as rejection capabilities, fouling resistance, and water permeability properties were also outlined.

“…Manganese, Zinc, Aluminium, Copper, Arsenic and Cadmium was often linked to this type of industry [8]. Researchers are usually connecting these metals pollutant with the Copper chrome arsenate (CCA) wood treatment [9,10,11,12]. While not denying these factors, it is essentials to study the other possible factor of this source of pollution.…”

The elemental composition of wood chip samples manufactured in the wood industries at Batu Pahat were analyzed for their heavy metals composition. This study was aimed to prove that heavy metals can accumulate in wood and trees themselves without adding any wood treatment additives. ICP-MS analysis was conducted on the wastewater at the same manufacturing industry to evince the occurrence of the leaching process that causes the presence of heavy metals in the wastewater. The results of the experiments showed that Mn, Zn and Al were among the highest metal traces found in the wood chips. As a result, Mn concentrations in three different samples of wood chips were 83.6 mg/L, 88.1 mg/L, and 80.9 mg/L, whereas Zn amounts were 38.8 mg/L, 40.2 mg/L, and 37.7 mg/L. Furthermore, the amounts of Al traces in the three samples were 28.2 mg/L, 29.6 mg/L, and 30.7 mg/L, respectively. The study also found that the highest metal trace in wastewater shows a proportional value to the highest concentration of heavy metals in wood chips. Therefore, it can be concluded that, even though the whole chipping production process is considered to be a dry process, the wastewater generated after cleaning surfaces, storage tanks and machinery, causes heavy metal leaching and contributes to the presence of heavy metals in wastewater.

“…With the rapid development of industry, more and more industrial wastewater is discharged into the environment without sufficient treatment, resulting in increasingly serious pollution of water resources. , Common pollutants in the water environment include organic dyes, heavy metals, pesticides, antibiotics, and hormone drugs. − Among them, dyes are the main source of water pollution, which are widely used in papermaking, textile, leather, printing, and dyeing industries. − Rhodamine B (RhB), a xanthene-type cationic dye, is commonly used in rubber, paper, and plastic manufacturing industries. − Insufficient treatment for RhB in water bodies could result in environmental pollution and cause harm to human health . Therefore, the removal of RhB is of great significance.…”

In this paper, phosphoric acid (H 3 PO 4 ), hydrochloric acid (HCl), and hydrogen peroxide (H 2 O 2 ) were employed for the modification of oil-based drill cutting ash (OBDCA) for the first time. The adsorption of rhodamine B (RhB) on modified oilbased drill cutting ash (MOBDCA) in an aqueous medium was investigated. H 2 O 2 -modified OBDCA had the optimal adsorption efficiency for RhB. The physical and chemical properties of MOBDCA were analyzed using X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), ζ-potential, N 2 adsorption−desorption isotherm, and pore size distribution. The effect of the pH value (3−11), reaction time (10−720 min), and initial RhB concentration (10−200 mg/ L) on RhB adsorption was discussed. The adsorption kinetics highly fitted with the pseudo-second-order model (R 2 > 0.99), which indicated that the adsorption process was dominated by chemisorption. The adsorption isotherm fitted well with the Langmuir and Freundlich models (R 2 > 0.97), which indicated the monolayer adsorption process and the heterogeneous adsorption process, respectively. The theoretic adsorption capacity (50 mg/g) for RhB was achieved by H 2 O 2 -modified OBDCA. This paper provides a promising method of resource utilization of OBDCA to treat organic pollutants.
