HEAVY-MEDIA SEPARATOR
a unit process used to separate materials
of differing density by "floaUsink" in a
colloidal suspension of a finely ground
dense mineral. This suspension, or media,
usually consists of a water suspension of
magnatite. galena or ferrosiiicon. (I)
HIGH GRADE PAPER
relatively valuable types of paper such as
computer printout, white ledger, and tab
cards. Also used to refer to industrial trimmings
at paper milis that are recycled. (7)
HUMUS
organic materials resulting from decay of
plant or animal matter. Also referred to as
compost. (7)
HYDROGEOLOGY
the study of surface and subsurface water.
(7)
IMPERMEABLE
resistant to the flow of water or other fluid.
(1)
IN-VESSEL COMPOSTING
a composting method in which the compost
is continuously and mechanically mixed
and aerated in a.large, contained area. (7)
INCINERATION
1. A waste disposal technology of the
thermal destruction type. In incineration,
combustion of wastes in the presence of
excess oxygen produces water, carbon
dioxide and ash, as well as noncombustible
residuals. If combustion is
incomplete, other organic by-products may
occur. 2. The controlled process by which
solid, liquid, or gaseous combustible
wastes are burned and changed into
gases; with the residue produced containing
little or no combustible materials.
(2)
INCINERATOR ASH
the remnants of solid waste after com-
bustion, including non-combustibles (e.g..
metals) and soot. (7)
INCINERATOR GASES
combustion gases which may contain water
vapor and excess or dilution air added
afler the combustion chamber. (1)
INCINERATOR
types:
90 Envlronmental Packaging Guidelines
CENTRAL
a conveniently located facility that burns
solid waste collected from many different
sources.
CHUTE FED
charged through a chute that extends
one or more floors above the furnace
grate.
COMMERCIAL
a predeslgned, shop-fabricated unit possibly
shipped assembled as a package,
for consuming general refuse.
INDUSTRIAL
an incinerator specifically designed to
burn a particular industrial waste,
usually under 2 tons per hour (50tpd).
MUNICIPAL
privately or publicly-owned, primarily
designed and used to burn household
and commercial solid wastes, usually
over 2 tons per hour (+50tpd).
ON-SITE
burns waste on the property of the generator
of the waste.
RESIDENTIAL
a predesigned, shop-fabricated and
assembled unit, shipped as a package
for individual dwellings.
INCINERATOR
1. An engineered apparatus used to burn
waste substances and in which all the
factors of combustion (temperature,
retention time, turbulence, and com-
bustion air) can be controlled (I). 2. A
facility in which the combustion of solid
waste takes place. (7)
INDUSTRIAL PLASTIC SCRAP
material originating from a variety of inpiant
operations and which may consist of
a single material or a blend of known composition.
(5)
INDUSTRIAL WASTE
materials discarded from industrial operations
or derived from manufacturing processes.
(7)
INERT MATERIAL
materials lacking active thermal, chemical
or geological properties. (1)
