The adsorption/bio-oxidation process (AB process) is a variation of the activated sludge process used in wastewater treatment. This two-stage system combines a high-rate adsorption stage (A-stage) with a lower-rate bio-oxidation stage (B-stage). A...
This page provides a list of wastewater treatment technologies:
The Haber process, also called the Haber–Bosch process, is the main industrial method for making ammonia. It combines nitrogen from the air with hydrogen, using an iron catalyst, to form ammonia (NH3). Most of the ammonia is used to make nitrogen...
Miray Bekbölet is a Turkish environmental chemist researching oxidation techniques, photocatalytic and photolytic reactions, adsorption/bio-oxidation processes in aquatic systems, and drinking water quality. She is a professor of environmental...
Metal-organic frameworks (MOFs) are a class of coordination polymers built from metal nodes, discrete metal ions or metal-oxo clusters, commonly described as secondary building units (SBUs), joined by organic ligands to form one-, two-, or...
Titanium was first introduced into surgeries in the 1950s after having been used in dentistry for a decade prior. It is now the metal of choice for prosthetics, internal fixation, inner body devices, and instrumentation. Titanium is used from head...
Activated carbon, also called activated charcoal, is a form of carbon commonly used to filter contaminants from water and air, among many other uses. It is processed (activated) to have small, low-volume pores that greatly increase the surface area...
Trinitrotoluene ( TRY-ny-troh-TOL-yoo-een, try-NY-), more commonly known as TNT (and more specifically 2,4,6-trinitrotoluene, and by its preferred IUPAC name 2-methyl-1,3,5-trinitrobenzene), is a chemical compound with the formula C6H2(NO2)3CH3. TNT...
Gold extraction is the extraction of gold from dilute ores using a combination of chemical processes. Gold mining produces about 3,600 tons annually, and another 300 tons is produced from recycling. Since the 20th century, gold has been principally...
A biogas upgrader is a facility that is used to concentrate the methane in biogas into biomethane, also known by its trade name as Renewable Natural Gas. Upgrading has three main functions: removal of trace contaminants, separation of non-methane...
