Answer:
Water treatment: Using sodium hydroxide's by product (chlorine or cl2) we can disinfect /kill the germs in the water.. this is known as water treatment.
Factories release a lot of sewage and chemical water which are waste and either acidic or basic in nature, we can use acid or base to neutralize them so salt and water forms which are harmless and not toxic and they can be released to sea, this is factory water treatment.. but the reason why factories are not doing because they overlook the disadvantages of untreated sewage and it will cost them to treat it so they just let it as it is...
British poet W. H. Auden once noted, “Thousands have lived without love, not one without water.” Yet while we all know water is crucial for life, we trash it anyway. Some 80 percent of the world’s wastewater is dumped—largely untreated—back into the environment, polluting rivers, lakes, and oceans.
This widespread problem of water pollution is jeopardizing our health. Unsafe water kills more people each year than war and all other forms of violence combined. Meanwhile, our drinkable water sources are finite: Less than 1 percent of the earth’s freshwater is actually accessible to us. Without action, the challenges will only increase by 2050, when global demand for freshwater is expected to be one-third greater than it is now.
Sip a glass of cool, clear water as you read this, and you may think water pollution is a problem . . . somewhere else. But while most Americans have access to safe drinking water, potentially harmful contaminants—from arsenic to copper to lead—have been found in the tap water of every single state in the nation.
Still, we’re not hopeless against the threat to clean water. To better understand the problem and what we can do about it, here’s an overview of what water pollution is, what causes it, and how we can protect ourselves
