Textile industry produces millions of tons waste annually, which is predominantly incinerated or landfilled. Cotton textile comprises a quarter total production, and although being renewable, its production highly chemical- water-intensive, rising the need for effective cotton recycling. This study presents an investigation whether it possible to utilize as cellulose source fabrication membrane...

Abstract Membrane filtration is vital in our daily lives to extract fresh water from contaminated water. However, membrane suffering fouling, which induced by accumulations of particles on surface. Due the hydraulic field and electrical (from functional groups membranes) near surface, particle will be exerted different forces. The intermolecular forces such as Lateral lift force, Brownian shear...

The innovative design and synthesis of membranes with silver incorporated surfaces open up new avenues for applied basic functions.

A novel polyacrylonitrile (PAN)-based ultrafiltration (UF) hollow-fiber membrane was newly synthesized for nanofiltration (NF) applications. This semi-fully NF characterized using a variety of analysis techniques. The exhibited higher negative charge and hydrophilicity lower surface roughness compared to the pristine UF membrane. Experiments study performance fouling were simulated under labora...

BACKGROUND In spite of many peritoneal tests proposed, there is still a need for a simple and reliable new approach for deriving detailed information about peritoneal membrane characteristics, especially those related to fluid transport. METHODS The sequential peritoneal equilibration test (sPET) that includes PET (glucose 2.27%, 4 h) followed by miniPET (glucose 3.86%, 1 h) was performed in ...

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...

The microbiological quality of effluents from different macrofiltration systems (pressure sand filter and disc filter) used as pre-treatment and membrane technologies (microfiltration and ultrafiltration) was evaluated in order to determine their possible application as alternatives to disinfection of urban wastewater prior to reutilization. Microbiological quality was determined by reference t...

The interest in separating and concentrating bioactives minerals from seaweeds extracts is growing due to large health benefits of these substances. aim this study was investigate the separation components Fucus vesiculosus seaweed by tangential ultrafiltration apply Hermia’s models adapted crossflow understand fouling mechanism. influence membrane cut-off varying 5 150 kDa, velocity 0.081 0.09...

The flux decline behaviour of some charged proteins and of binary mixtures of charged solutes during unstirred dead-end ultrafiltration has been studied. The mixtures consisted of the proteins bovine serum albumin, (BSA), cy-lactalbumin and/or lysozyme. Of special interest were a-lactalbumin and lysozyme because these proteins are physico-chemically identical, except for the sign of their charg...
