Oxidation-Reduction Potential
The electric potential required to transfer electrons from one compound or element (the oxidant) to another compound (the reductant); used as a qualitative measure of the state of oxidation in water treatment systems.
Supercritical Water Oxidation or SCWO
A type of thermal treatment using moderate temperatures and high pressures to enhance the ability of water to break down large organic molecules into smaller, less toxic ones.
Oxidation - A process that results in a species having a higher oxidation state, that is, the net loss of electrons from an atom. Quite often oxygen is involved in the oxidation of another atom; therefore it is an oxidant.
Oxidation
the chemical or biochemical change that occurs when a substance combines with oxygen, for example during combustion and respiration; the release of carbon dioxide and energy from organic compounds ...
Oxidation: A chemical reaction in which ions are transferring electrons, to increase positive valence.
Oxidation pond: A man-made body of water in which waste is consumed by bacteria.
Oxidation Pond
A man-made (anthropogenic) body of water in which bacteria, used most frequently with other waste-treatment processes, consume waste; a sewage lagoon.
Oxidation ...
oxidation-reduction reaction A chemical transformation in which electrons are transferred from one chemical (the reducing agent) to another chemical (the oxidizing agent).
Oxidation: A substance containing oxygen that reacts chemically to produce a new substance.
Oxidation: A reaction in which oxygen combines with another substance.
Ozone (O3): A very reactive oxidant containing three atoms of oxygen.
Oxidation Pond is a basin to retain wastewater before final disposal. Bilogical oxidation of organic matter occurs by natural or artificial transfer of oxygen to the water from air.
Oxidation: The chemical reaction of a substance with oxygen or a reaction in which the atoms in an element lose electrons and its valence is correspondingly increased.
oxidation : Oxidation is the addition of oxygen, removal of hydrogen, or the removal of electrons from an element or compound. In the environment, organic matter is oxidized to more stable substances. The opposite of reduction ...

Epoxidation
A reaction wherein an oxygen molecule is inserted in a carbon-carbon double bond and an epoxide is formed.

autoxidation
Reaction with dioxygen at moderate temperatures.
autoxidation (in food chemistry)
Apparently spontaneous, usually slow reaction of foodstuff components with dioxygen in an aerobic environment at moderate temperatures.
In-Situ Oxidation: Technology that oxidizes contaminants dissolved in ground water, converting them into insoluble compounds.
Oxidation-Reduction (redox): A chemical reaction consisting of two half-reactions; an oxidation reaction in which a substance loses or donates electrons, and a reduction reaction in which a substance gains or accepts electrons.
Oxidation burning in oxygen, normally highly exothermic (heat releasing), but also any increase in oxidization sate, (i.e. loss of electrons). Results in the formation of an oxide, rusting or corroding.
...
Oxidation
The chemical reaction on the surface of a coin, caused by exposure to air, dampness, industrial fumes, or other elements capable of reacting with oxygen.
sewage oxidation pond (See sewage lagoon)
sewage sludge
sewage sludge treatment ...
Anaerobic oxidation of carbohydrates and carbohydratelike compounds by enzyme action of microorganisms; gaseous oxygen is not involved in this energy-yielding process.
Ferro-Humic Podzol ...
Advanced oxidation process: One of several combination oxidation processes. Advanced chemical oxidation processes use (chemical) oxidants to reduce COD/BOD levels, and to remove both organic and oxidisable inorganic components.
Biological Oxidation- Decomposition of complex organic materials by microorganisms. Occurs in self-purification of water bodies and in activated sludge wastewater treatment.
Oxidation of organic matter releases CO2 to the atmosphere, and regional and global impacts may result. dendrochronology The dating of past events and variations in the environment and the climate by studying the annual growth rings of trees.
Without tarnish or oxidation, and with original cartwheel (i.e. frosty) or prooflike lustre. A copper coin is usually referred to as brilliant if it has full original red.
Nitrification The biological oxidation of ammonia and ammonium sequentially to nitrite and then nitrate. It occurs naturally in surface waters, and can be engineered in wastewater treatment systems.
The process of bioremediation can be monitored indirectly by measuring the Oxidation Reduction Potential or redox in soil and groundwater, together with pH, temperature, oxygen content, electron acceptor/donor concentrations, ...
Respiration is the oxidation of food (carbohydrates) which results in the release of energy in the form of ATP. Respiration occurs in the cytoplasm and mitochondria in a controlled step-by-step fashion.
Combustion (by chemical oxidation) of waste material to treat or dispose of that waste material
ISO 14001
The international standard for companies seeking to certify their environmental management system ...
Some oxidation reactions can release large amounts of heat and gases, and, under the right conditions, cause an explosion. Others can cause rapid corrosion of metal, damage to tissue, burns and other serious effects.
Nitrification: biochemical oxidation of ammonia (NH3), ammonium (NH4), or atmospheric nitrogen (N) to nitrate (NO3) or nitrite (NO2).
Substance produced during the burning or oxidation of a material.

organotrophy nutrition in which energy is gained from the fermentation or oxidation of organic compounds
orthograde referring to straight distribution, as in a vertical oxygen or temperature profile
orthophosphate inorganic phosphate ...
Primary treated water. First major treatment in a wastewater treatment facility, usually sedimentation but not biological oxidation.
Often this term is used to mean additional treatment after tertiary treatment for the purpose of further removing contaminants of concern to public health. This may include membrane filtration, reverse osmosis (RO), advanced oxidation, ...
Oxidation:a chemical reaction involving the combination of a material with oxygen.
P
Period:the time between two successive waves. Pipe:a narrow passageway that leads from a magma reservoir to a vent.
