MembraneFiltrationDye RemovalThis study was focused on the fabrication of nanoporous poly(vinylidene fluoride) (PVDF) membranes at different polymer concentration (14, 17, and 20wt%) via phase inversion method. The morphology and surface roughness of the resulting membranes were investigated by ...
The introduction of TMC can reduce the inherent pore size of TpPa, and form a continuous and highly porous network structure, so that the COFs modified membrane can have excellent seawater desalination performance. These solutions effectively address the drawbacks of membrane surface modification ...
The PVDF production line for decoration is the requirement of the customer's PVDF membrane performance through the in-membrane composite process of the two extruders. According to the equipment used and the shape of the processed product, the temperature is controlled between 210 and 220 degrees Ce...
In this paper, ionic liquid 1-butyl-3-methylimidazolium tetrafluoroborate was the first time successfully utilized as single solvent in preparing the PVDF membrane with a good performance by N-TIPs method. The effects of quenching temperature and hydrophilic additive content on the morphology, permeabil...
However, attaching zwitterion in/on the hydrophobic membrane is difficult because of the difference in their hydrophobicity. Yang et al. (2018) successfully synthesized SBMA with poly(arylene ether sulfone) (PAES) to form a novel zwitterionic copolymer, and then blended it with a PAES casting ...
However, unsep- arated flocs after the coagulation process typically collect at the surface of the membrane and form a cake layer containing many bacteria, which together with their associated extracellular polymeric substances (EPS), can lead to both reversible and irreversible membrane fouling. ...
Full size image Integrating PVDF and TiO2for methylene blue removal The limitations accompanied by membrane separation processes and photocatalytic degradation of contaminants can be solved by coupling both methods to form a hybrid system named photocatalytic membrane reactors (PMRs) (Samuel et al.2022)...
membrane. For the contact angles of sludge foulants, the sludge is first filtrated on the membrane surface to form a cake layer and then kept in an oven for 24 hrs at 40 °C to remove water. In order to get a sludge plane, a glass plate was placed on it in order to flatten...
(PVDF) has been the most commonly used piezoelectric polymer, which can be directly polarized to form piezoelectric membranes through electrostatic spinning20,21. Feng et al. stitched a PVDF nanofiber membrane as a piezoelectric layer and two conductive fabrics as an electrode layer to form a ...
