Answers
Answer:
In water and purified water ,there is a small difference between them in the usual water there is the normal number of calcium and magnesium salts but in the purified water there is the the optimum quantity of magnesium and calcium salts.
Answer:
what is purified Water?
Purified water is water that has been filtered or processed to remove impurities like chemicals and other contaminants.
It is usually produced using groundwater or tap water.
Through purification, many types of impurities are removed, including (1Trusted Source):
Bacteria
Algae
Fungi
Parasites
Metals like copper and lead
Chemical pollutants
Several methods are used to purify water commercially and in the home.
In most Western countries, public drinking water is purified to make water safe for human consumption.
However, standards for drinking water around the world vary and are typically based on governmental regulations or international standards.
In fact, the World Health Organization estimates that over 2.1 billion people lack access to safe drinking water (2Trusted Source).
In countries that purify public drinking water, various treatment methods are used to make water safe, including (3Trusted Source):
Coagulation and flocculation: Positively charged chemicals are added to water to bind with negatively charged particles so they can be filtered out. This forms larger particles called floc.
Sedimentation: Due to its larger size, floc settles to the bottom of the water supply, separated from the clean water.
Filtration: The clean water on top of the supply then flows through numerous filtration systems made of sand, charcoal and gravel. This removes contaminants like dust, bacteria, chemicals and viruses.
Disinfection: During this step, chemical disinfectants like chlorine are added to the water to kill any remaining bacteria or viruses that may have survived the first few steps.
It’s important to note that water may be treated differently depending on the area and quality of the local water.
SUMMARY:
Purified water is water that has been processed to remove contaminants like dirt and chemicals. In many countries, tap water is purified to make it safe for human consumption
