NERV (Reactor)
Encyclopedia
The NERV is a specialised bioreactor
, designed to operate under high and varying load and flow conditions.
The NERV system allows the bacteria cultures within the reactor to be controlled both by type and volume. Fresh bacteria are bred and cultured outside of the reactor; regular dosing ensures that a constant supply of fresh bacteria is always on hand, even during periods of low nutrient values or high toxicity. This ensures that cultures are not 'wiped out' and that immediate recovery of bio-remediation takes place.
NERV is more compact than traditional technology and during times of low nutrient levels the bacteria enter the state of endogenous
respiration
, a situation where they eat their own biomass. This results in dramatically lower sludge production compared with traditional biological systems. this technology benefits from a much smaller footprint than traditional systems and the concept of breeding bacteria outside of the unit removes the reliance on self generating bacteria within the system giving it the ability to absorb toxic shocks and extreme nutrient variations.
A typical NERV installation would be a cooked meat production plant with regularly washed down ovens. The effluent from such a factory would be very high in FOG (fats, oils and grease) but would frequently contain cleaning fluids and biocides. The bacteria in a traditional treatment system would be killed by this kind of shock, rendering the systems useless. Some food plants alternate their wash downs to be acidic and basic
to avoid build up of resistant organisms, a properly set-up NERV reactor can deal with this variation.
Bioreactor
A bioreactor may refer to any manufactured or engineered device or system that supports a biologically active environment. In one case, a bioreactor is a vessel in which a chemical process is carried out which involves organisms or biochemically active substances derived from such organisms. This...

Endogenous
Endogenous substances are those that originate from within an organism, tissue, or cell. Endogenous retroviruses are caused by ancient infections of germ cells in humans, mammals and other vertebrates...

Cellular respiration
Cellular respiration is the set of the metabolic reactions and processes that take place in the cells of organisms to convert biochemical energy from nutrients into adenosine triphosphate , and then release waste products. The reactions involved in respiration are catabolic reactions that involve...

Base (chemistry)
For the term in genetics, see base A base in chemistry is a substance that can accept hydrogen ions or more generally, donate electron pairs. A soluble base is referred to as an alkali if it contains and releases hydroxide ions quantitatively...
