This document provides an overview of industrial pollution, its causes and effects, and methods for controlling it. It discusses various industrial effluents from food, textile, oil refinery, and metal coating industries. For each industry, it identifies the main pollutants in effluents and recommends treatment methods, such as physical, chemical or biological, to remove pollutants before releasing wastewater. The document emphasizes that selecting the proper treatment technology depends on identifying and characterizing the pollutants in each effluent.

4. Introduction
 With the coming of the Industrial Revolution,
humans were able to advance further into the 21st
century. Technology developed rapidly, science
became advanced and the manufacturing age
came into view.
 With all of these came one more effect, industrial
pollution. But when these factories became full
scale industries and manufacturing units, the issue
of industrial pollution started to take on more
importance.

5. Industrial Pollution
 Any form of pollution that can trace its immediate
source to industrial practices is known as industrial
pollution. Most of the pollution on the planet can be
traced back to industries of some kind

7. Effects of Industrial Pollution
 1. Water Pollution:. Most industries require large
amounts of water for their work. When involved in a
series of processes, the water comes into contact with
heavy metals, harmful chemicals, radioactive waste and
even organic sludge.
 2. Soil Pollution: Soil pollution is creating problems in
agriculture and destroying local vegetation. It also
causes chronic health issues to the people that come in
contact with such soil on a daily basis.

8. Effects of Industrial Pollution
 3. Air Pollution: Air pollution has led to a steep
increase in various illnesses and it continues to
affect us on a daily basis. With so many small, mid
and large scale industries coming up, air pollution
has taken toll on the health of the people and the
environment.
 4. Global Warming: With the rise in industrial
pollution, global warming has been increasing at a
steady pace. Smoke and greenhouse gases are
being released by industries into the air which
causes increase in global warming

Pollution
 1. Read labels and reject products
 2 .Reject companies and products
 3 .Investigate where a company's plants are located
 4 .Read reports from environmental groups
 5.Conserve electricity

12. Industrial Effluent Treatment
 . The specifications for releasing various types of
industrial effluents into the public sewer network or
to surface watercourses is not only determined by
the concentration of biological oxygen demand
(BOD), chemical oxygen demand (COD) and
suspended solids, but also by the content of
organic and inorganic elements, which vary from
country to country.
 In general, therefore, selecting a treatment method
for industrial effluents depends primarily on the
following factors:

13. Factors of selecting a treatment method for
industrial effluents
Identifying the
various pollutants
present in the
effluent;
Characterizing the
effluent;
Regulating the
sewers and
separating the
waste streams;
Selecting the
treatment
technology based
on the different
available physical,
chemical or
biological treatment
capabilities.

14. Technology
Description
 Industrial effluents (primarily from factories and
plants) contain various materials, depending on the
industry. Some effluents contain oils and grease,
and some contain toxic materials (e.g., cyanide).
Effluents from food and beverage factories contain
degradable organic pollutants. Some effluents
contain, while others lack, nutritious materials
suitable for microbiological growth.

15. Treatment of Food Industry Effluents
 Food industry effluents are generally characterized
by a high content of biodegradable pollutants.
Suspended substances constitute a large part of
these pollutants, in addition to the high BOD and
COD concentrations of the effluents.
 These effluents are treated with biological methods
as a primary treatment

16. Treatment of Textile Industry Effluents
 The pollutant content of textile industry effluents
typically contains
 (1) natural and artificial treated fibers,
 (2) dyes, and
 (3) used materials (especially coloring materials).

17. Treatment of Oil Refinery Effluents
 The basic constituents of oil refinery wastewaters
are hydrocarbons. Other materials include (1)
organic materials (phenol, alcohols), (2) sulfuric
compounds (sulfide, mercaptan, and sulfate), (3)
sodium salts, and (4) suspended solids (sand, etc.).
 Treatment of the wastewater is done in two main
stages, including
 (1) physical-chemical treatment
 (2) Biological treatment

18. Treatment of Metal Surface Coating
Industry Effluents
 Some materials are used to coat metals, primarily
to prevent corrosion of the metal. The water
resulting from this industry typically contains (1)
high concentrations of toxic metals, and (2) diluted
rinse water.
The resulting wastewater is treated with physical-
chemical methods

19. Conclusion
 The issue of industrial pollution concerns every
nation on the planet. As a result, many steps have
been taken to seek permanent solutions to the
problem. Better technology is being developed for
disposal of waste and recycling as much polluted
water in the industries as possible.
