- Abstract:
- ... Nanofiltration membrane with high water permeability and anti-fouling nature is particularly needed to be explored in dyeing wastewater treatment. Herein, a hydrophilic calcium carbonate/polyethyleneimine-gallic acid (CaCO3/PEI-GA) loose NF membrane was prepared via a layer assembled in-situ mineralization (LAIM) strategy. This strategy endowed the membrane with the following advantages: the forma ...

- Abstract:
- ... An interface-strengthened cross-linked graphene oxide/Nafion212 (CLGO/Nafion212) composite membrane was successfully fabricated and served as ion conducting membrane for vanadium flow batteries (VFBs). Firstly, the surface of Nafion212 was endowed with plenty of amino groups via in situ sol-gel chemistry approach of 3-aminopropyltriethoxysilane. Subsequently, a thin layer of m-xylylenediamino-cros ...

- Abstract:
- ... Membrane cleaning is crucial to maintain the permeability and selectivity of membranes. Physical cleaning can mitigate membrane fouling, lower the frequency of chemical cleaning, thus prolong membrane lifetime, and reduce operational costs. Backpulsing is a promising physical cleaning method, which can effectively mitigate external and non-adhesive fouling and has been used in many industrial fiel ...

- Abstract:

However, those models could not simulate the membrane fouling behaviors accurately because of the large number of fitting parameters related to feed water quality and flow pattern in a membrane filtration system. In this study, we developed a deep neural network (DNN) to model membrane fouling ...

- Abstract:
- ... Membrane distillation (MD) is a promising green technology that can utilize waste heat to concentrate non-volatile solutes, or remove volatiles and dissolved gases from an aqueous feed. The primary reason for the limited commercial implementation of MD is membrane pore-wetting, which deteriorates the separation performance. For oily wastewater, the surfactants are particularly detrimental due to t ...

The silk cocoons contain two proteins- 65–85% silk fibroin (SF) and 15–30% of SC. During the silk degumming process, SF is extracted by dissolving in sodium carbonate (Na2CO3), to remove the SC. Although SF has various applications in vivid fields, SC ...
