Microfiltration is a ubiquitous and often crucial part of many industrial processes, including biopharmaceutical manufacturing. Yet, all existing filtration systems suffer from the issue of membrane clogging, which fundamentally limits the efficiency and reliability of the filtration process. Herein, we report the development of a membrane-less microfiltration system by massively parallelizing ...

With the development of refining industry, treatment refinery wastewater has become an urgent problem. In this study, a ceramic membrane (CM) was combined with Fenton-activated carbon (AC) adsorption to dispose wastewater. The effect process analyzed using excitation–emission matrix (EEM), ultraviolet-visible (UV-vis) and Fourier transform infrared spectroscopies (FTIR). Compared direct filtrat...

photocatalytic membranes exhibit great potential for water treatment since they combine the filtration and photo degradation in a single unit. although blending photocatalytic nanoparticles into polymeric thin film remains the simplest method to prepare the photocatalytic membrane, the entrapped photocatalyst showed less catalytic activity due to the agglomeration and shielding effects in the p...

The objective of this research was to evaluate the potential for separating α-lactalbumin from pasteurized milk by using tangential flow membrane filtration. Filtration was carried out with a Purosep 7000 series membrane filtration unit (SmartFlow Technologies) with a regenerated cellulose membrane at 26°C and a transmembrane pressure of 186 kPa. The protein in the permeate was >80% α-lactalbum...

the goal of this study was the evaluation of semen extender filtration on post-thawed buck sperm quality. a total 16 ejaculates were collected from four buck (4 ejaculates from each buck) twice a week. after semen collection and primary evaluation, collected semen samples were pooled and divided into two equal parts. each part was diluted with one of the following extenders: 1) non-filtered lec...

Pressure-driven processes have come a long way since they were introduced. These processes, namely Ultra-Filtration (UF), Nano-Filtration (NF), and Reverse-Osmosis (RO), aim to enhance the efficiency of wastewater treatment, thereby aiming at cleaner production. Membranes may be polymeric, ceramic, metallic, or organo-mineral, filtration techniques differ in pore size from dense porous membrane...

This study investigated filtration behaviors of polysaccharides solutions, both alone and in mixture with proteins, in the short-time constant flux filtration with the focus on factors affecting the transmembrane pressure (TMP) increase rate, the irreversible filtration resistance, and the membrane rejection behavior. The results showed that the TMP increase rates in the short-time constant flu...
