Reverse osmosis is a type of water filtration that removes potentially harmful compounds from drinking water. Many bottled water companies use reverse osmosis to purify their products. Drinking reverse-osmosis water offers some health benefits -- and a few potential disadvantages.
WaterPurifiers is the removal of contaminants from raw water to produce drinking water that is pure enough for human consumption or for industrial use.
Substances that are removed during the process include parasites (such as Giardia or Cryptosporidium) , bacteria, algae, viruses, fungi, minerals (including toxic metals such as Lead, Copper etc.), and man-made chemical pollutants.
Many contaminants can be dangerous—but depending on the quality standards, others are removed to improve the water's smell, taste, and appearance.
A small amount of disinfectant is usually intentionally left in the water at the end of the treatment process to reduce the risk of re-contamination in the distribution system.
