Question

what will happen if the acidc industrial waste water are dumped into rivers without treating them.
(please give only right answer)​

Answer 1

if the acidic industrial waste are dumped into rivers without treating them it will have adverse effects on aquatic life. it makes the river water acidic and toxic which leads to death of aquatic life.

Answer 2

Answer:

If acidic industrial waste water are dumped into rivers withy treating them, then the rivers might get polluted and the organisms in the rivers would die or get diseases. This will also lead to the increase of pH level of the water thereby harming the aquatic plants and animals.

✯What is Industrial Waste?

We have millions of factories, mills, industries, mining plants, etc. around the world. These industries use raw materials to produce finished goods for consumers. But in the manufacturing process, there are materials which are rendered useless.

They constitute the industrial waste. Some examples of industrial wastes are metals, paints, sandpaper, slag, ash, radioactive wastes, etc. In this article, we will discuss different types of industrial wastes and their disposal.

✯Types of Industrial Waste

Industrial waste can be categorized into biodegradable and non-biodegradable.

☆ Biodegradable

• Those industrial wastes which can be decomposed into the non-poisonous matter by the action of certain microorganisms are the biodegradable wastes. They are even comparable to house wastes. These kinds of waste are generated from food processing industries, dairy, textile mills, slaughterhouses, etc. Some examples are paper, leather, wool, animal bones, wheat, etc.

☆ Non-biodegradable

• Those industrial wastes which cannot be decomposed into non-poisonous substances are the non-biodegradable wastes. Examples are plastics, fly ash, synthetic fibres, gypsum, silver foil, glass objects, radioactive wastes, etc.

✯Sewage Treatment

Human health and environment are mainly affected by the direct disposal of industrial and human effluents into natural resources without any treatment. Sewage treatment is necessary to reduce the toxicity of sewage and maintain a safe and healthy environment, as well as promote human welfare.

✯Sewage Treatment Process

Sewage contains a huge amount of organic matters which are toxic. Microorganisms are widely used in the sewage treatment plant for removing this toxic organic matter. Sewage or wastewater treatment plant consists of two stages.

☆Primary Treatment

• It involves the removal of large or small-sized components in the wastewater through physical processes.

☆Biological Treatment:

• Aerobic microorganisms are inoculated into the sewage treatment plant. These microbes utilize the organic components of the sewage and reduce the toxicity. This can be measured by BOD (Biological oxygen demand).

• After the biological treatment, the sludge is pumped from the treatment plant into a large tank. This large tank consists of anaerobic bacteria which lead to the digestion of sludge. During digestion, biogas is produced and it is used as an energy source. Hence, Sewage treatment plant design and sewage management play a crucial role in the maintenance of human welfare.

✯Energy generation

• Microorganisms which are involved in the production of energy are called microbial fuel cells. Microbial fuel cells are used to generate a variety of energy sources like biogas and electricity. Agricultural waste, manure, and domestic wastes are used as raw materials for the generation of biogas. Biogas generation is done in the large concrete tank which is called a biogas plant.

• Biomasses (Biowastes) are collected at the biogas plant and the slurry is fed. Biomasses are rich in organic matter. Some of the bacteria can grow anaerobically inside the biogas plant. These bacteria can digest the biomasses which are present in the slurry and sewage. During digestion, a huge amount of mixture of gases is released inside the tank. The mixture of these gases is called the biogas. Biogas is removed from the biogas plant through a separate outlet.

• Microbial fuel cells are also used to generate electricity from wastewater. Microbial fuel cells utilize the organic matter from the wastewater treatment plant. During digestion, organic matters are converted into the simple molecule and release the carbon dioxide and electrons. Those electrons are absorbed by the electrode and used as the source of electricity.
