Difference Between Osmosis and Reverse Osmosis. Is it Safe?

The main difference between osmosis and reverse osmosis is that the osmosis is the diffusion of water molecules from high to a lower water potential across a semipermeable membrane whereas the reverse osmosis is the diffusion of water molecules across a semipermeable membrane against the potential gradient. Furthermore, osmosis is a natural process, while reverse osmosis is an artificial process.

Osmosis is a process by which water molecules of a solvent tend to pass through a semipermeable membrane from a less concentrated solution into a more concentrated one. On the other hand, reverse osmosis is a process by which water molecules of a solvent passes through a semipermeable membrane in the direction opposite to that of natural osmosis when subjected to a hydrostatic pressure higher than osmotic pressure. Osmosis occurs through a potential gradient, while reverse osmosis occurs against the potential gradient. Osmosis occurs during absorption of water from the soil by roots and opening the stomata while reverse osmosis used in the water purification systems.

Is reverse Osmosis water better for you?

Reverse Osmosis is a type of filtration process. In RO untreated water, like saltwater, flows through a semipermeable membrane and carbon filters. The size of the membrane lets the water flow through the filter, but leaves behind salt, chemicals, and impurities. The result is pure water that is free from minerals and bacteria as well. Now the question is reverse osmosis water better for us? The answer is Yes! Water that is processed by the reverse osmosis process is drinkable because the RO process is used in the areas where water has an abundance of saltwater. It can be the right way for you to feel safe about the water that you are drinking. If pesticide or herbicides are a concern in your community, then reverse osmosis is the best option to make your water clean. 

Is Reverse Osmosis water bad for you?

As we all know, every system has advantages as well as disadvantages. Same with reverse osmosis process. As in the RO process, it can not differentiate between bad and good ingredients. So while harmful contaminants are being removed, so are the trace minerals that need to perform properly, like iron and manganese. Also cooking with demineralized water, like reverse osmosis actually reduces the amount of vitamins and minerals found in whole foods. In fact WHO released a report about its concerns over release reverse osmosis water and over the fact that much attention has been given on how the process removes contaminants. The report also stated that reverse osmosis water has a definite adverse influence on the animal and human organism.

Can filtration remove bacteria?

Only a reverse osmosis water filtration system will effectively remove harmful bacteria. The simplest way to remove harmful bacteria is to disinfect the water by chlorination or by ultraviolet radiation. Some water filters may also allow bacteria to multiply to great levels on the filter pads if they are not maintained regularly. In most circumstances, domestic household water filters or ultraviolet treatment systems will not make water safe in relation to amoeba unless you also disinfect with chlorine.
