Health Benefits of RO Water

Poor quality water has been linked to a wide range of physical health problems such as gastrointestinal, high blood pressure, immune deficiency and cancer.

Because of this more and more people today are looking for ways to ensure that their water is a quality that will protect them and their family from any unwanted chemicals, metals, additives and dirt particles that can more readily get into water that is not filtered. But there is good news.

Today there are many more options to clean and filter water than ever before. One of the best ways to make sure that the water quality in a home, business or office is of good quality is to purchase a reverse osmosis system that has a proven track record to reduce and remove harmful chemicals, metals, additives and dirt particles.

In the past, older water filtration systems used a charcoal system that required filter replacement from the counter top every 100-200 gallons and reduced water contaminants in smaller amounts. But today through advanced technological breakthroughs water filtration systems have a much longer life and provide a much higher filtration capability against contaminants.

What is Reverse Osmosis?

Reverse osmosis (RO) is a water purification technology that employs the use of semi-permeable membrane to purify water. Reverse osmosis involves passing water through a semipermeable membrane which is small enough to allow water molecules to pass through as well as getting rid of larger molecules.

Reverse osmosis involves the use of an applied pressure to overcome osmotic pressure. This process can get rid of numerous types of ions and molecules from water such as bacteria. Reverse osmosis is used in both industrial and residential production of water. During the production, the solute is usually retained on the pressurized side of the membrane while the pure solvent is on the other side of the membrane.

The membrane is designed in a way thus inhibits large molecules to pass through thus is able to separate clean and safe water from water with impurities. The normal osmosis process involves the movement of water from an area of low solute concentration to an area of high solute concentration through a semi-permeable membrane.

The movement of pure solvent is triggered by the need to reduce the free system energy by balancing the concentration of solutes on the two sides of the membrane, thereby generating osmotic pressure. Reverse osmosis can therefore be described as application of external energy to reverse the natural flow of a solvent. This reverse osmosis process is to an extent similar to other membrane technology applications.

However, reverse osmosis and filtration have some key differences. Filtration involves straining the solvent molecules as its predominant removal mechanism. This works by forcing the huge molecules to be unable to pass through the membrane regardless of the solvent concentration or pressure. However, reverse osmosis factors in diffusion as the process is pressure and flow rat dependent. Most products on the market have to be certified by the NSF, a public organization that vets many companies for public health and safety.

Reverse osmosis is well known for its use in the production of drinking water, where seawater is purified by removing salts as well as other effluent materials.

Reverse Osmosis Membrane

Membranes are some of the most important parts of reverse osmosis. Most of the membranes used in commercial reverse osmosis plants are made from cellulose acetate, polyamide and polysulfonate.

The membrane is usually made up of a 0.25 microns skin and a 100 microns of support layer. The skin is usually the barrier that allows only water molecules to pass through. Water purified through the reverse osmosis method usually has an amount of dissolved solids that is approximately a constant percentage of the dissolved minerals in feed water.

For instance, if the feed water has 400 ppm total dissolved solids (TDS), the product water may have 40 ppm or 20 ppm reflecting a 90% and 95% rejection ratio respectively.

A Reverse Osmosis system design is usually based on feed water TDS; the percentage or recovery and percentage of rejection desired. The higher the recovery percentage, the lower the refection percentage, the poorer the product water quality becomes.


​Since the discovery of reverse osmosis, this system has become one of the world most useful technological breakthroughs. It has served a great purpose of provision of safe water for drinking at a cost effective price. This technology is not only used to purify drinking water, it is also used in many other areas. As I conclude, I want to take you through some of the areas where reverse osmosis has had great impact.

Drinking Water​

Reverse osmosis is providing safe water for drinking in many households across the world. Corporations are turning to RO systems to quench their employees thirst while companies are bottling RO purified water. The U.S. military serves between 1000 and 6000 soldiers with RO water while NBC (Nuclear/Biological/Chemical agents) use RO water for their operations.​

Waste Water​

Collected rainwater is usually used as feed water in Reverse Osmosis Systems and used for industrial cooling and irrigation. Big power plants use RO to get rid of minerals from water used in boilers. This helps in using pure water in the boilers as it doesn’t leave deposits that corrode and damage the machinery. Singapore announced their intention of treating their waste water using RO system before re-introducing them back into the reservoirs.​

Food Industry

​Reverse osmosis is used in food factories to thicken food liquids like tomato and orange juice, which when processed with heat lose their nutritional values. RO is used in concentration of milk and whey protein powder production in dairy industry. RO is used to remove acetic acid, alcohol and smoke in wine industry. RO is used to get rid of excess water from maple sap. This system removes 80% of water thus reducing the boiling expenses of the syrup.​

Car Wash

​Car wash entrepreneurs use reverse osmosis machines to treat hard water. Hard water is known to cause spotting on vehicles. By treating it with reverse osmosis, the heavy minerals in this water are removed. This also leads to lower demands by customers to have their vehicles dried, thus cutting on costs.​

​Reef Aquariums

Reef aquarium keepers have realized that tap water has dissolved chlorine, heavy metals, chloramines, nitrogen compounds and phosphates which are not ideal for the artificial mix of sea water.​

You have now seen the how important reverse osmosis is in our day to day lives. Reverse osmosis does not only produce drinking water but water for many other uses as evidenced above. Reverse osmosis is very ideal in our homes as it ensures that you will never expose your family to diseases resulting from use of contaminated water.​
