Bacterially assembled biopolyester nanobeads for removing cadmium from water

Safer sips: removing arsenic from drinking water.

U.S. researchers are developing technologies that may someday protect millions of people worldwide whose drinking water is tainted with arsenic. Arsenic is released into water from soil and rock erosion, and is also a by-product of industrial processes including semiconductor manufacturing, petroleum refining, and mining and smelting operations.

Iron Foundry Slags for Removing Arsenic from Water

An Adaptation Method for Removing Arsenate Species from Water Solution

This paper is based on the idea of adaptation under which we mean the replacement of one element in a system with another with similar aspects. The first adaptation comes from the replacement of orthophospheric acid H3PO4 by arsenious acid H3AsO4. There is a close relation between calcium-sulfate and calcium carbonate-arsenate species. The main objective of this note is to give an explicit form...

Membrane bioreactor process for removing biodegradable organic matter from water.

This research investigated a membrane bioreactor (MBR) process for removing biodegradable organic matter (BOM) and trihalomethane (THM) precursors from pre-ozonated water. Bench-scale and mini-pilot-scale MBR experiments were conducted using powdered activated carbon (PAC) and acclimated biomass. Dissolved organic carbon (DOC) was removed through a combination of adsorption and biodegradation m...

An Enhanced Median Filter for Removing Noise from MR Images

In this paper, a novel decision based median (DBM) filter for enhancing MR images has been proposed. The method is based on eliminating impulse noise from MR images. A median-based method to remove impulse noise from digital MR images has been developed. Each pixel is leveled from black to white like gray-level. The method is adjusted in order to decide whether the median operation can be appli...
