Wastewater Management TechniquesWastewater:-First of all we don't have to know what wastewater is. Any water contaminated by human waste or waste from other harmful substances is specifically defined as "wastewater". There are several human activities that are polluting our water and ultimately putting our lives at risk or we can even say they are slowly poisoning us humans. Wastewater Contaminants: - Contaminants include detergents, soaps, oils, chemicals, artificial colors, waste, lubricants, medicines, human waste, animal waste, microbes, and sometimes even food. In our country, industrialists build large factories but do not take adequate measures for the disposal of waste which can be in the form of liquids or in the form of toxic gases. Factories directly discharge waste liquids into the sea or rivers. Fish can consume these toxic chemicals and die or begin to build up in their bodies. When we humans eat those fish, the toxin will transfer into our body and cause us diseases. There is a certain amount of these contaminants that can be tolerated by the human body. If the amount is more than tolerable, it can lead to disastrous effects and ultimately death. In order to save our environment and our lives, scientists have designed some techniques by which this waste can be recycled, reused or disposed of. Waterborne Diseases: There are many diseases caused by drinking wastewater or polluted water. diseases include:1. Amoebiasis;2. Cholera;3. Dysentery;4. Diarrhoea;5. Malaria;6. Polyomavirus infection;7. Poliomyelitis mellitus.Techniques for wastewater management:-There are some techniques that can help us to... middle of paper......depending on the condition of the liquid. The same is the case here; in this process industrial wastewater is treated with an acid or base to maintain the pH of the water. Since we all know that lime is a base, it is then added to acidic waste to neutralize it. Coagulation: Coagulation is the process by which a chemical is added to water which forms insoluble products which are eventually eliminated from the system. The final products serve to remove substances from wastewater. His examples include the use of multipurpose metals; lime, ferric chloride, ferric sulphate and aluminum sulphate. They are typical coagulants. Adsorption: Activated carbon is used to adsorb substances onto it. Ion exchange: Ion exchange was previously used to remove small ions from wastewater, but is now not widely used. This process involves the exchange of some ions with other ions.
