1.7 Delimitation of the Study
The
study covered River Atuwara in Otta Municipal Districts. The major
polluting industries in the industrial layouts will be determined in the
three major industrial areas in Otta viz: Idiroko road, Ijoko road and
Lagos-Abeokuta expressway. A modelto simulate one-dimensional
hydrodynamic and water quality parameters of the receiving streams will
be examined.
1.8 Operational Definition of Terms
Industrial
pollution: is a very broad category of pollution resulting from
manufacturing activities. Industrial pollution can be in the form of air
pollution, water pollution or solid and hazardous wastes.
Industrial
wastes: industrial and radioactive waste from chemical plants and
nuclear power plants includes potentially dangerous substances such as
petro-chloro-benzene (PCBs), tributylin (TBT), organo-chlorides, heavy
metals (HMs), acidic wastes, radioactive caesium and plutonium
239,(Falconer ,1990).
Industrial effluent: These are partially
treated or untreated wastewater discharges from industries. It is
normally unacceptable to discharge untreated industrial wastewater
direct to rivers, land or disposal down mineshafts wells etc. Gaseous
discharges from stacks are also part of industrial effluent.
Industrial
wastewater management: This is the process that ensures the
minimization of wastewater production for recovery and reuse. The
recovery and reuse of wastewater in an economic way enable the cost of
wastewater treatment to be minimized. The options for the industrialist
are: (1) to treat or partially treat at source within the site;(2) treat
at a centralized works effluents plant within the industrial complex or
(3) discharge the wastewater to a sewer and pay for off site treatment.
Water
quality: a term used to describe the chemical, physical and biological
characteristics of water, usually in respect to its suitability for a
particular purpose.
Mathematical model: Mathematical models are
useful instruments in the survey of computer systems. It is not possible
to survey the many components and their reactions in an ecological
system without the use of mathematical models as synthesis tool.
Mathematical models can be used to reveal dynamic system properties.
They revealed gaps in knowledge on ecological systems and can therefore
be used to set up research priorities as an idealized formulation that
represents the response of a physical system to external stimuli.

ABSRACT - [ Total Page(s): 1 ]This study examined the effects of effluent discharges from various point-loads on a purposively selected receiving river, the self-recovery ability of the river and the treatability of both the discharges and the receiving stream in a heavily industrialized community.The work involved field survey of industries producing and discharging effluents in the study area (Ado Odo/ Otta industrial zone of Ogun State, Nigeria); determination of the effluents‘ physico – chemical, biological ...
