Hard water is water having a high mineral content, such as sulphates, bicarbonates, and carbonates of calcium and magnesium.
You must have heard about reverse osmosis. It is one of the most well-liked and promising processes for purifying water. Up to 99%+ of the dissolved salts (ions), particles, colloids, organics, bacteria, and pyrogens from the supply water, can be eliminated via reverse osmosis.
RO Plants are the most widely used methods of purifying drinking water. Here, the question arises! Does RO Plant remove the hardness of water?
Let’s see if the RO plant removes the hardness of water (Calcium & Magnesium)!
About 95–99% of TDS is removed from drinking water by reverse osmosis systems. Minerals are easily removed from the RO membrane at high osmotic pressure, because they are heavier than water particles.
The most frequent minerals removed by RO Plants are calcium, phosphorus, and magnesium, while many other minerals are also eliminated.
How does Reverse Osmosis remove the hardness of water? (Calcium and Magnesium)
Several filtration stages and a semi-permeable membrane make up a RO Plant. Each filter effectively removes a high degree of organic and inorganic contaminants; for example, a sediment filter may get rid of bigger impurities, while an activated carbon filter gets rid of things like lead and chlorine chemicals. Yet, the semi-permeable membrane is what gives reverse osmosis its many benefits.
Since, many minerals are less than 1 micron in size, they can pass through a typical filtration system without coming into contact with the medium and being removed, yet being too small to be seen. Yet, a RO membrane has incredibly small pores—0.001 microns—that can catch contaminants of various sizes, while letting only clean water molecules pass through. This is how you may make tap water safe to drink.
Concerns regarding magnesium and calcium in drinking water
Reverse osmosis is used to purify water, but there are issues with this method, specifically the removal of minerals and possible health effects.
The World Health Organization is particularly concerned about the removal of calcium and magnesium, and its negative consequences on health. These worries revolve on the possibility that adding more calcium and magnesium to water, could lower the prevalence of cardiovascular disease.
The majority of magnesium and calcium, however, probably originate from food consumption rather than water sources. Hence, concerns regarding its elimination must be weighed, against how much one can expect to consume from meals.
Reverse Osmosis eliminates fluoride and cadmium-containing minerals, by forcing water under pressure through a semipermeable membrane. Reverse osmosis is used to extract the heaviest components, since mineral particles are heavier than water particles.
In addition to these minerals, RO systems also get rid of a tonne of other impurities like lead, arsenic, microorganisms that cause illness, pesticides, and hazardous dissolved impurities like nitrates, chromium, and sulphates.
