1.1 Industrial Wastewater Pollution In recent year due to the development in many industries such as light and heavy industries, it bring the higher potential effect to the environment. Even thought, these industries can give the benefits to the economy around the world, but the creation of the pollutant from these industries will produce the large amount of waste that harmful to human and environment. There are many kind of pollution likes water, air, noise and soil pollution that come out from the increasing of development industries. Water pollution one of the serious problem that arise where it can give biggest impact to the human, environment and other living thing as the water is a basic need for human, animals and plant. Water pollution is the serious ecological threat that should to be overcome as well as to reduce the pollution.
Although this chemical process made improvements to the industry, its products were a huge source of air pollution to the surrounding areas, in particular, the hydrochloric acid produced in the reaction caused major air pollution. There was much controversy over the pollution caused by the process and it was partly this reason why the leblanc process became obsolete when a new method was found by the Belgian chemist, Ernest Solvay.

Organic effluents such as domestic sewages are a serious problem and the discharge of small quantities of sewages into the aquatic systems can actually increase the productivity of ecosystems, however, excessive quantities will deplete oxygen content, causing severe threat to aquatic life. As a result, the presence of organic and inorganic pollutants in aquatic system continues to be one of the most important environmental issues of the world
Global trends such as urbanization and migration have increased the demand for water, food and energy. Development of human societies is heavily dependent upon availability of water with suitable quality and in adequate quantities, for a variety of uses ranging from domestic to industrial supplies and Rapid industrialization is adversely impacting the environment globally. Pollution by inappropriate management of industrial wastewater is one of the major environmental problems in India as well, especially with small scale industrial sector in the country. To address the pollution coming out from industries, adoption of cleaner production technologies and waste minimization initiatives are being encouraged. The present case studies on Common Effluent Treatment Plants (CETP) for Textile industry are considered as one of the viable solution for small to medium enterprises for
Most industries requires large amounts of water for their work. When involved in a series of processes the water comes into contacts with heavy metals, harmful chemicals, radioactive waste and even organic sludge. These are either dumped into open ocean or rivers, or the water that has been polluted by them is released into the ground. As a results, many of our water sources have trace amounts of industrial waste in them and it seriously impacts the health of our eco-system. This water is used for irrigation, washing our food at home and sometimes recycled into drinking water.
Many factors cause water pollution to occur and increase over the years. The most important thing uses to cause water pollution is sewage pollution of boundary waters. Sewage mentions to fluid wastes containing a combination of human feces and wastewater from non-industrial human hobbies such as soaking, washing, and cleaning. In countless poor areas of the world, sewage is dumped into innate waterways, in the nonexistence of useful alternatives. Untreated sewage poses a main risk to human condition as it contains waterborne pathogens
This is known as nonpoint-source pollution. (Adapted from: www.explainthatstuff.com) Water pollution is happening everywhere but this investigation is focused on water pollution in Ga-kgapane and how the increase in population has led to an increase in this pollution. One of the main causes for water pollution in this town is: • The disposal of waste products in the streams • The washing of clothes and other things in these streams • Human activities such as swimming and playing in these streams Water pollution has become a growing problem in this town and has led to a lot of other issues that should be
2. Reasons and Problems related to Wastewater Quality of water is a serious issue across the world and uncontrolled disposal of municipal, industrial and agricultural liquid, solid, and gaseous wastes poses serious threats to the sustainability. This has led to the contamination of air, water and soil along with its contribution to global warming. There are several factors which are responsible for continuous degradation of water quality like increasing population, industrialization and urbanization. As the demand of potable water is increasing, the need of treatment and safe disposal of wastewater is becoming essential to safeguard public health and reduce unbearable levels of environmental deterioration.
Urbanisation and industrialisation has resulted in an increase in the amount of wastewater discharged into the environment. The main objective of wastewater treatment is to enable the safe disposal of sewage/wastewater and to minimise the dangers wastewater can impose to the public and
Now a day’s water pollution is a major and most important problem due to discharge of untreated industrial effluents into nearby water bodies [36, 37]. Water pollution problem is present in both developing and developed countries. Human activities are major contributors to water pollution. The polluting substances include pathogenic organisms, plant nutrients that stimulate algal blooms, inorganic and organic toxic substances . Water used in every industry and effluent is disposed to the environment leading to the surface and ground water pollution .
