fouling of microfiltration and ultrafiltration membranes

Fouling of Microfiltration and Ultrafiltration Membranes

Membrane filtration (microfiltration and ultrafiltration) has become an accepted process for drinking water treatment, but membrane fouling remains a significant problem. The objective of this study was to systematically investigate the mechanisms and components in natural waters that contribute to fouling. Natural waters from five sources were filtered in a benchtop filtration system.

Comparison on efficiency of various techniques

The term bio refers to the life which here means the micro organism that can be potentially used to treat waste water treatment. Several microorganisms were employed to remove nutrients and toxic chemicals. Todd and Josephson employed biological methods for treatment of sewage water. Twelve key factors were discussed including mineral diversity

Micro and nanobubble technologies as a new horizon

It has been reported that MBs and NBs can detoxify contaminated water by catalyzing the reactions of chemicals, thereby improving the efficiency of the chemical treatment process , . According to several studies, bubbles generated from air and nitrogen could enhance the activities of microorganisms and/or bacteria in both anaerobic and aerobic

TiO2 Coating and UV Photofunctionalization Enhance Blood

This in vitro study was designed to evaluate the effect of sol-gel derived TiO<sub>2</sub> coating on blood coagulation, blood protein adsorption, and platelet response on zirconia surfaces. Square-shaped zirconia (n=96) (10x10x2 mm) was cut, ground, sintered, and finally cleansed ultrasonically in each of acetone and ethanol for 5 minutes. Three experimental groups (n=32) were fabricated: (a

Carbon-based supercapacitors for efficient energy storage

In particular, Zhang et al. recently developed a plasma treatment approach to fabricate 3D N-doped graphene aerogel/Fe 3 O 4 nanostructures, which showed a specific capacitance of 386 F/g in 6 M KOH electrolyte with a 97% retention rate after 1000 cycles . In-situ growth of active materials on a graphene substrate can achieve high energy

More information about NIH grant numbers and tips for searching: NIH grant numbers, e.g., 5R01CA101211-03, typically have three main parts: 1. A prefix that indicates the type of grant, e.g., 5R01. 2. An 8-character serial number consisting of a 2-letter NIH institute/center code and a 6-digit number, e.g., CA101211. 3.
