Introduction: Foot-and-mouth disease (FMD) is a highly contagious and economically devastating viral disease of livestock that is categorized in list A of animal diseases by the World Organisation for Animal Health (OIE). Vaccination is effective against FMD and the vaccine production centers largely use the industrial ultra-filtration and chromatography in order to remove the cellular proteins...
Wastes generated from the processing of some fruits still contain large amounts of chemical components such as polyphenols, which are deemed as very effective antioxidants.This study involves the characterization of wastes generation by pink guava processing and selection of the best solvent that will allow us to extract the excess polyphenols via ultra-filtration membran...
Fast reduction of blood water volume due to ultra-filtration via hemodialysis machine and critical threshold of blood water volume can result in clinical complications such as hypotension. When blood water volume reduces during hemodialysis process, the concentration of blood forming elements will increase. One of the methods for the monitoring of the concentration changes is ultrasonic speed m...
New nanofiltration membranes were produced in the form of unfilled fibers through the photopolymerization method. Parastyrene sodium sulfonate was used as the vinyl monomer to reform the polysulphone ultra-filtration membranes. The modified membranes were used to purify colored solutions of three different pigments consisting acidic, reactive and direct (suitable for dyeing pile yarns and ...
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...
