“…The EPS and SMP can bring about the deterioration of filterability in the MBR . The main components of SMP and EPS are carbohydrates, protein and humus, and carbohydrates and proteins also play an important role in membrane fouling . Additionally, some studies show that viscosity has ties to MLVSS and filamentous microorganisms .…”

BACKGROUND The principal purpose of the present work was to explore the mechanism of mitigation of membrane fouling in a periodic reversal submerged electro‐coagulation membrane bioreactor (SECMBR) with Fe–C electrodes. In this study, membrane resistance and activated sludge performance were compared in a SECMBR and a conventional submerged membrane bioreactor (SMBR). RESULTS Adsorption fouling had a strong direct correlation with the soluble microbial products (SMP) and carbohydrates in SMP and had a moderate correlation with the mixed liquor volatile suspended solids, viscosity and average particle size. SECMBR enhanced the flocculation of suspended sludge, decreased the absolute value of the ζ potential, and maintained microbial activities. With increasing proportion of oil shale wastewater, more soluble microbial products were secreted by microorganisms in the SECMBR than in the SMBR. CONCLUSION Electrocoagulation technology has the capacity to increase the sludge particle size and decrease the absolute value of the ζ potential to alleviate cake layer fouling and total resistance. As the proportion of oil shale wastewater was increased, microbial activity in the conventional MBR was inhibited, leading to less secreted SMP and a lower adsorption fouling rate. The results provide insight into understanding the mechanism of mitigation of membrane resistance in an SECMBR. © 2018 Society of Chemical Industry

“…The release of herbicides, personal care products, pesticides, and pharmaceuticals are the several types of organics expelled into natural water by humans, causing adverse health effects to aquatic life and mankind. The adsorption efficiency of CNMs for the removal of these effluents depends on the chemical nature of organic wastes to be removed, the physiochemical properties of NMs (e.g., pore size and pressure of surface charges), and water solution chemistry such as ionic strength and pH [154][155][156]. The pollutants having aromatic rings in their structure develop π-π interactions with carbon nanomaterials, which favors the removal process of these pollutants from water [157].…”

The utilization of biomass waste to produce valuable products has extraordinary advantages as far as both the economy and climate are concerned, which have become particularly significant lately. The large-scale manufacturing of agricultural waste, mainly rice by-products (rice husk, rice straw, and rice bran), empowers them to be the most broadly examined biomasses as they contain lignin, cellulose, and hemicellulose. Rice waste was first used to incorporate bulk materials, while the manufacturing of versatile nanostructures from rice waste at low cost has been developed in recent years and attracts much consideration nowadays. Carbon-based nanomaterials including graphene, carbon nanotubes, carbon dots, fullerenes, and carbon nanofibers have tremendous potential in climate and energy-related applications. Various methods have been reported to synthesize high-value carbon nanomaterials, but the use of green technology for the synthesis of carbon nanomaterials is most common nowadays because of the abundant availability of the starting precursor, non-toxicity, low fabrication cost, ease of modification, and eco-friendly nature; therefore, reusing low-value biomass waste for the processing of renewable materials to fabricate high-value products is remarkable. Carbon nanomaterials derived from rice waste have broad applications in various disciplines owing to their distinctive physicochemical, electrical, optical, mechanical, thermal, and enhanced biocompatibility properties. The main objective of this review and basic criteria of selecting examples and explanations is to highlight the green routes for the synthesis of carbon nanomaterials—i.e., graphene, carbon nanotubes, and carbon dots—from rice biomass waste, and their extensive applications in biomedical research (bio-imaging), environmental (water remediation), and energy-related (electrodes for supercapacitors, Li-ion battery, fuel cells, and solar cells) applications. This review summarizes recent advancements, challenges, and trends for rice waste obtained from renewable resources for utilization in the fabrication of versatile carbon-based nanomaterials.

Boron nitride nanosheets (BNNSs), so‐called “white graphene”, have recently received increasing attention, both theoretically and experimentally. Although many synthetic procedures have been proposed for the synthesis of BNNSs, finding a simple, solvent‐less, catalyst‐free, and large‐scale production route is still a challenge. Here, a facile, solvent‐less, low cost, and high yield process is developed, in which mechanical solid‐state exfoliation allows scalable production of crumple BNNSs from commercial BN powders with a high surface area. Importantly, these BNNSs show unprecedentedly high adsorption of proteins described by various adsorption isotherms and kinetics models. In addition, the saturated BNNSs exhibit excellent recyclability, and maintain a high sorption capacity even after five cycles through simply regeneration process of heating in air. This easy recyclability route further demonstrates the great potential of BNNSs for water cleaning application.
