In order to recover lithium from brine with a high Mg2+/Li+ ratio, positively charged nanofiltration (NF) membrane was prepared by depositing polydopamine (PDA)-coated graphitic carbon nitride (g-C3N4) as the interlayer (PDA-g-C3N4) and interfacial polymerization (IP) of polyethyleneimine (PEI) trimesoyl chloride (TMC) carried out. Under optimal conditions, water contact angle composite is only...

Cellulose nanocrystals (CNCs) are biodegradable nanoparticles with a high aspect ratio and abundant surface hydroxyl groups resulting in negatively charged hydrophilic surfaces that make them an ideal candidate to be incorporated thin-film nanocomposite (TFN) membranes. In this study, we modified the CNCs via acetylation (ACNCs) reduce their hydrophilicity reaction L-cysteine (CysCNCs) impart f...

The rejection of anti-inflammatory drugs by membranes has shown paramount importance in separation membrane processes such as nanofiltration and reverse osmosis (NF/RO) for pharmaceutical industries. Therefore, the main objective this paper is to use support vector machine (SVM) artificial neural network (ANN) model rejections NF/RO using 300 experimental data points gathered from literature. B...

1. Introduction One of the scientific challenges in nanofiltration is to develop nanofilters with both high ion permeability and selectivity, which are often considered as antagonist features. Today, the number of solid state membranes that are readily useable is limited and their performances, i.e. ion permeability and selectivity, are restricted. New materials for nanofiltration are thus clea...

Despite of their low concentration, the impact of steroid estrogens such as estrone, 17a-estradiol, and ethinylestradiol are often more serious than other synthetic endocrine-disrupting chemicals (EDCs) because their endocrine-disrupting potency is much higher. Although their existence in waterways is of increasing concern, nanofiltration (NF) and reverse osmosis (RO) are likely to play an impo...

Whey is the major by-product of cheese industry which contains valuable organic materials. Further processes are needed before these materials can be used in food industry. Membrane filtration a convenient alternative to traditional processes. Low energy consumption, reduced processing costs and enhanced quality products main benefits membrane filtration. Due advantages techniques have affected...

Polymeric filtration membranes could be a cost-effective alternative to cation exchange (CEMs) in electrolysis with contained anolyte and saltwater catholyte because they size selectively hinder salt ion transport between compartments while facilitating proton hydroxide transport. Optimizing membrane performance requires better understanding of properties that impact electrical resistances rete...

Polyamide (PA) nanofiltration (NF) membranes suffer from biofouling, which will deteriorate their separation performance. In this study, we proposed a strategy to incorporate silver nanoparticles (Ag NPs) into PA NF in situ, order simultaneously enhance water permeability and antibacterial The chloride-doped carbon quantum dots (Cl-CQDs) with photocatalytic performance were pre-embedded the sel...

• Commercial nanofiltration membranes show high rejection towards RAS-relevant off-flavor compounds and contaminants of emering concern. Water productivity, need pretreatments, partial all the salts nontoxic organic matter are concerns for integration in RAS. Nanofiltration can be used to avoid accumulation unwanted RAS with degree recirculation. The large number innovations proposed recent yea...

Abstract Recent research proclivity is about supplying water for drinking, urban and industrial applications which recognized as one of the most significant challenges that threaten humanity. Giving its simplicity high efficient yield, membrane technology has been preferred compared to other separation technologies wastewater treatment. In present research, KIT-6 (KIT: Korea Advanced Institute ...
