Novel biological process for removing perchlorate

Field Demonstration of a Novel Biotreatment Process for Perchlorate Reduction in Groundwater

Removing ambiguity from the biological species concept.

The biological species concept (BSC) is a common way to define species although it is ambiguous even when strictly applied. I interpret it here syntactically in four different ways and show that one of them is more suitable than previously thought. The first interpretation (fully restricted) produces discrete, non-overlapping biological species with the inconvenience of being inapplicable when ...

Electro-Oxidation as an Effective Process for Removing Antibiotics and Persistent Organic Compounds Resistant to Biodegradation

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...

LITHIUM PERCHLORATE MEDIATED AMINATION REACTION OF ALDEHYDES: A NOVEL METHOD FOR SYNTHESIS OF N, N-DIALKYL-p-SILYLATED AMINES*

P-Silylated N,N-dialkyl amines (5) were easily synthesized in good to excellent yield from aldehydes (1), trimethylsilyldialkylamines (2), and trimethylsilylmethylmagnesium chloride (4) in the presence of 5 M lithium perchlorate solution in diethyl ether. The reaction Of (2) with aldehyde proceeded smoothly in the LiCI0 , to give the imimum salt (3). Addition of trimethylsilylmethylrnagnes...
