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.

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

Causes of Industrial Pollution

1. Lack of Policies to

Control Pollution

2. Unplanned Industrial Growth

of Policies to Control Pollution

3. Use of Outdated

Technologies

4. Presence of Large Number of Small Scale

Industries

5. Inefficient Waste

Disposal:

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.

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

Principle of Industrial Pollution Control

Treatment of wastes, discharges

and disposals.

Reducing consumption or usage

of a polluting product

Proper method

for productio

n

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

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:

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.

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.

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

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).

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

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

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.
