Questions about Reverse Osmosis Systems

Reverse Osmosis is a fascinating method of filtering water. There are many questions that are commonly asked when the topic of reverse osmosis comes up. Read on to find the answers to the most common questions asked about reverse osmosis.



How much water is wasted with RO?

Many people don’t realize how much water is wasted when water is filtered using reverse osmosis. For every gallon of water filtered, a reverse osmosis system wastes about four gallons of water. The average person uses roughly three gallons a day for cleaning, cooking and consumption. This means that a person wastes twelve gallons of water in order to make use of three gallons of water.


The other side of the argument of whether reverse osmosis is wasteful or not is that reverse osmosis doesn’t use electricity or waste energy by heating water.

Simply put, reverse osmosis can be considered wasteful if you think about how much water is wasted to make a gallon of filtered water. However, it can be considered conservative when you take into account the fact that no electricity or energy is wasted to heat the water.


Is RO water good for me?

Reverse osmosis water is a very controversial topic. However, it is considered safe by the

general population. The reason it is controversial is because it is often pitted against other methods of water purification such as deionization.


RO water typically has about 5-40 ppm (parts per million) of impurities. Deionization

typically has around 0-1 ppm. You should never drink completely pure amounts of water in large amounts because it will act as a leech. It has the potential to harm and even kill a human-being because completely pure water leeches the minerals from your body.


After reading the above, it is safe to conclude that RO purified water is actually better for you than water purified through other methods.


Is there any health risks?

RO water is considered quite safe by the general population. However, the WHO (world

health organization) has recently released a report about RO water.


Simply put RO water might be too safe. As already mentioned above when talking about

deionization. RO water might be too pure which might make the water leech minerals from the body. The best solution would be to install an RO filter that is good at filtration but isn’t excellent at it.


The fact of the matter is that the human body needs certain minerals that it gets from impure water such as magnesium and calcium.


No need to worry just yet as more research is needed and for now RO water seems perfectly fine to consume.


How does it work?

Reverse Osmosis works by using a semipermeable membrane to remove ions, molecules and larger particles from drinking water. A few of the impurities that are commonly found in tap water which reverse osmosis filtration can remove are fluoride, lead, detergents, nitrates, sulfates and pesticides.


Reverse osmosis is much simpler than it sounds. Simply put, it refers to forcing contaminated water through a membrane to make pure drinking water. Energy is required to force the water to move against what it normally would do. Electrically powered pumps are often used to force the water to flow like this. Reverse osmosis is considered capable at removing certain pollutants such as salt, limescale and the above-mentioned impurities. However, it is less effective at removing certain bacteria and other types of impurities.


What does RO water remove?

Reverse osmosis removes plenty of impurities. It removes fluoride, lead, chlorine and

chloramine, pesticides, detergents, nitrates and sulfates. It also removes sodium, sulfate, calcium, potassium, iron, zinc, mercury, selenium, phosphate, arsenic, magnesium, cadmium,barium and cyanide. As you can see RO water removes plenty of impurities which are harmful if ingested in large quantities.


What does Ro water taste like?

The taste of water depends on the minerals and other compounds that it picks up on its

journey. Simply put, the flavor of water depends on where the water has come from. For

example, water from a well may have a slightly mineral or chalky taste because of all the

layers of limestone it would have passed through underground. Water close to a beach

usually has a slight smell of sulfur because there are lots of sulfur-producing microbes

present underground.


Reverse Osmosis water removes all of these different minerals from water resulting in the water tasting differently from tap water. RO water can taste bad if the RO system

malfunctions. It can also begin to taste bad if the filters, membrane and other components of the RO system aren’t cleaned and sanitized regularly. For this reason, RO water filters are usually checked and replaced every six to eight months. The semipermeable membrane is also usually replaced every two years and the entire RO system is serviced every three months.

Is Reverse Osmosis Worth It?

Reverse Osmosis is worth it if you value your health in the long run. It is also worth it for the sheer convenience it offers you in terms of time and money saved. There are plenty of contaminants out there which pollute water regularly. The cost of investment is negligible if you think about how much money you can save in the long run.


Drinking contaminated water will sooner or later put you in the hospital. Hospital bills aren’t cheap and are much more expensive than an RO system. Also, you might be left with a condition that is untreatable. RO systems are entirely worth the money because they save you from a variety of diseases such as hardening of the arteries, arthritis, kidney stones, gallstones, glaucoma, cataracts, hearing loss, emphysema, diabetes, and obesity.


There is a reason that most businesses and almost all hospitals use RO water systems and that is because they give their employees clean and pure drinking water without worry and hassle.
