Question

1 Household water may contain salts in solution. 2 Water for household use is filtered to remove soluble impurities. 3 Water is treated with chlorine to kill bacteria. 4 Water is used in industry for cooling.​

Answer 1

Answer:

1. Salts and minerals like these typically present in trace amounts in your water and are very safe. "If you had pure water by itself, it doesn't have any taste," agricultural scientist Bob Mahler told Time in 2014. "So companies that sell bottled water will put in calcium, magnesium, or maybe a little bit of salt."

Answer 2

Domestic water may be salty in solution:

• Domestic water is filtered to remove soluble impurities.
• Water is treated with chlorine to kill germs.
• Water is used in the industry for cooling.
• Domestic water is filtered to remove soluble impurities:
• In an osmosis filtration system, water is transferred to a non-permeable membrane under pressure.
• This process forces water into the membrane while impurities such as fluoride, mercury, cysts, etc. remain in the membrane.
• The result is clean and safe drinking water.
• Water treated with chlorine to kill germs:
• Chlorination is the process of adding chlorine to drinking water to kill parasites, bacteria, and bacteria.
• Various procedures can be used to achieve safe levels of chlorine in drinking water.
• Consuming or drinking water with low levels of chlorine does not cause serious health problems and provides protection against waterborne diseases.
• Industrial water for cooling:
• Water cooling is a method of extracting heat from parts and industrial equipment.
• Evaporating cooling using water is usually more efficient than air cooling.
• Water is inexpensive and non-toxic but can contain dirt and cause rust.
• Water cooling is often used to cool the internal combustion engines of cars and power stations.
