MILLIGRAMS PER LITER (mg/l)
A weight-to-weight ratio; the milligrams per liter value
(mg/l) multiplied by the factor 8.34 shall be equivalent to pounds
per million gallons of water.
MUNICIPAL WASTEWATER
The wastewater of a community. From the standpoint of source,
it may be a combination of the liquid- and water-carried wastes from
residences, commercial buildings, industrial plants and institutions,
together with any groundwater, surface water and stormwater that may
have inadvertently entered the sewer system.
NATURAL OUTLET
Any outlet, including storm sewers, into a watercourse, pond,
ditch, lake or other body of surface water or groundwater.
NORMAL DOMESTIC SEWAGE
Sanitary sewage resulting from the range of normal domestic
activities in which BOD, SS and total kjeldahl nitrogen concentrations
meet the following:
[Amended by Ord. No. 469; Ord. No. 470]
(1)
A five-day, 20° C. BOD of not more than 250 mg/l.
(2)
A suspended solids content of not more than 250 mg/l.
(3)
A total phosphorus content of not more than 6.0 mg/l.
PARTS PER MILLION (PPM)
A weight-to-weight ratio; the parts per million value multiplied
by the factor 8.34 shall be equivalent to pounds per million gallons
of water; equivalent to milligrams per liter (mg/l).
PERSON
Any and all persons, including any individual, firm, company,
municipal or private corporation, association, society, institution,
enterprise, government agency or other entity.
pH
The logarithm of the reciprocal of the hydrogen ion concentration.
The concentration is the weight of hydrogen ions in grams per liter
of solution. Neutral water, for example, has a pH value of seven and
a hydrogen ion concentration of 10-7.
PRETREATMENT
An arrangement of devices and structures for the preliminary
treatment or processing of wastewater required to render such wastes
acceptable for admission to the public sewers.
PRIVATE SEWER
