Membrane Bioreactor for Wastewater Treatment

Recent technical innovation and significant membrane cost reduction have pushed membrane bioreactors (MBRs) to become an established process option to treat wastewaters. The combination of membrane separation with a suspended growth bioreactor is now widely used for municipal and industrial waste treatment (Judd, 2006). When used with domestic wastewater, MBR processes could produce effluent of high quality enough to be discharged to coastal, surface or brackish waterways or to be reclaimed for u ....etc

The application of Membrane Bioreactor (MBR) in waste water treatment is widespread. The Membrane Bioreactor process consists of a suspended growth biological reactor combined with a membrane unit located either external to the bioreactor or mounted within the bioreactor. Nowadays researchers have been exploring the use and extend of their applications for treatment of municipal and industrial waste waters. It is an efficient process for maintaining a long solids retention time(SRT) at a relatively short hydraulic retention time(HRT).While a hi ....etc

Membrane switch technology is a highly reliable interface solution with many advantages. The sealed nature of the overlays makes membrane switch technology an excellent front panel solution where environmental concerns are an issue. The success of any membrane switch design effort is facilitated by effective communication between the design engineers and the vendor. This design guide is intended as an outline for communicating the requirements of our customers to Nelson Nameplate Company. A mutual understanding of the technology is very benefic ....etc

Abstract

Oil in water (OW) emulsions were prepared by emulsifying the membrane (ME) on a large scale with a submerged stirrer cells using flat membranes, and a tubular cross-flow block. comparing the results obtained using flat or tubular membranes devices. Conventional ceramic micro filtration (MF) membrane (ZrO2 supported on TiO2), was used in both cases. The main advantage of these membranes is their low cost compared to other commonly used in the ME (SPG membranes) that involves reduction to 60%. The effect of operating parameters on the d ....etc

The Plasma Membrane and Homeostasis


Homeostasis Maintaining a Balance

Cells must keep the proper concentration of nutrients and water and eliminate wastes.

The plasma membrane is selectively permeable it will allow some things to pass through, while blocking other things.

Structure of the Plasma Membrane

Lipid bilayer two sheets of lipids (phospholipids).
-Found around the cell, the nucleus, vacuoles, mitochondria, and chloroplasts.

-Embedded with proteins ....etc

Proton Exchange Membrane FuelCell Characterizationf or Electric
Vehicle Applications

ABSTRACT

This paper presents experimental data and an analysis of a proton exchange membrane fuel cell system for electric vehicle applications. The dependence of the fuel cell system s performance on air stoichiometry, operating temperature, and reactant gas pressure was assessed in terms of the fuel cell s polarity and power density-efficiency graphs. All the experimen were performed by loading the fuel cell with resistive heater ....etc
