The Differences in the Process of RO/DI Water Treatment

by 1 Comment

Building engineers and sub-contractors who spend their time spec-ing out water filtration systems always ask, “What’s the difference between the processes of RO/DI water treatment and purification?”

Here is the short and simple answer: Reverse osmosis (RO) and deionized (DI) filters undergo different types of reactions to clean water. The process of RO involves the use of standard tap water to clean-up to make it roughly 90-99% pure. However, with DI water, the filters in the process exchanges both positive and negative molecules for the charged contaminants in water. DI filter and other similar processes are sometimes referred to as “water polishing”.

 

A Deeper Understanding of the RO Water Filtration Process

Reverse osmosis is the complete opposite of a natural process called osmosis. Osmosis is the movement of water molecules across a semipermeable membrane. Naturally, water will move from a low ion concentration to a higher ion concentration to create balance between the two environments. However, with reverse osmosis, water molecules are pushed from the high concentration (dirtier) side into the the other. Although this is not perfect, it is very cost effective, and the RO membrane can last for years if used properly. Most of the time the initial process of RO is used before other purification technology is used to remove the remaining 1-10%.

This type of water is great for use in data centers, labs, humidors, and manufacturing enterprises. The removal of the ions in the water is to prevent bacterial formation, static electricity, and white dust to be formed when the water is used with humidification systems.

How DI Water Filtration Compares to RO

Deionization has many names for it’s process: Ion Exchange, Strong Acid/Strong Base, and Polishing Nuclear Grade. This type of water filtration method is great in removing the additional ions and inorganic chemicals down to very low parts per billion (PPB) levels. This process makes it excellent for producing ultra-purified water at 18.2 Megohm. At this quality, this type of water is used for the most sensitive laboratory instruments. This allows for the instruments to detect chemicals even at extremely low concentration levels.

However, one thing to understand is that water at this level of purity degrades quickly. Deionization alone does not remove all types of contaminants like dissolved organic chemicals. The reason is due to no physical filters that can remove bacteria and particulates. Rather, this process should be used in parallel with the RO process.

Benefits of Using RO/DI Water and Ultrasonic Humidification for Cigar Humidors

When it comes to owning a cigar shop, the money maker does not necessarily lie in however many cigar brands the shop carries, but rather if the cigars can hold it’s natural flavoring and maintain it’s condition. This boils down to two factors – is the shop maintaining a perfect humidity level for the environment, and which type of water are they using for it?

 

The Difference in RO/DI Water for Cigar Humidors

Purified water is the solution for preserving any cigars in a walk-in humidor. In fact, the more purified the water is, the better it will be for the humidor. The difference between distilled water and RO/DI water is the end result of the water. Distilled water may still contain some minerals and other components, and is still slightly acidic (pH of 6). However, RO/DI water sits completely neutral at a pH of 7, and is the purest water that any cigar shop owner can get their hands on.

With a water so pure and free of any minerals and other particles, the risk of bacteria growth and white dust formation is significantly decreased to minimal appearance, if any. This prevents the risk of mold growing on the cigars, and helps keeps the humidification system in the walk-in humidor clean. RO/DI water is used with many different types systems for humidification, but one of the best and recommended methods of RO/DI water is for the use of “Ultra Sonic Humidification”.

Ultra Sonic Humidification for Walk-In Cigar Humidors

Maintaining a RH (relative humidity) level of 70% is tough to with most standard humidification systems, especially for a large walk-in humidor.

Keeping humidity level at optimal levels is challenging. Factors such as room size play such a large role. Many smaller capacity humidors cannot handle the large square or cubic footage, unless the humidor lines itself up with multiple units. However, with added machinery in the humidor increases the electricity expenditure, as well as reducing space by crowding.

That being said, the solution is to use a system that is capable of providing enough humidity for the humidor. However, to go one step further, the use of ultra sonic humidification with RO/DI water is even more preferred.

Ultra sonic humidification requires the use of pure water that dispenses a cool mist of air to control humidity levels. The benefits of this system is the complete control of RH for the room, the ability to maintain humidity with a non-bacterial environment. It also helps preserve the life and value of any cigar around the world. This type of system is perfect for walk-in humidors of any size.

The Quick and Easy Basics of Ultrasonic Humidification and RO/DI Water

Humidification is the chemical process of transforming water into vapor. These vapors can be emitted as either warm or cool air (steam vs. mist). In order to take the necessary steps to protect against the culmination of bacteria in your home or work environment, first we must understand how the process works, what RODI water is, and how these two work together.

 

Isothermal vs. Adiabatic Humidification

There are many uses for humidifiers — you may use the system to get rid of dry environments in your home or office, to produce clean breathable air, or to fight bacteria that float around, invisible to the naked eye. In order to maintain relative humidity, RH, it is important to know exactly how the system works.

Steam generating humidifiers (isothermal) and high-pressure atomizing (adiabatic) humidifiers are the two different types of humidification processes. With isothermal humidification, the water vapor is dispersed in the air after having been created by boiling water. In the commercial HVAC world, isothermal humidification has been used most commonly for applications such as: steam-to-steam, gas-to-steam, electric steam, infra-red, and direct steam injection.

With adiabatic humidification, the water goes through a fine process to atomize it. The water is then released into the air. The main difference between the two is that there is no involvement of thermal energy from external sources, so the water that is released is a cool mist, rather than a hot steam. This advantages of this over isothermal humidification is that it saves significant energy, is easy to install and retrofit, simple to operate and maintain, and most important, will give you precise humidity control.

What Really is RO/DI Water?

Reverse osmosis (RO) water is a type of water that has been forced through a special membrane under pressure. This process produces water that is about 98% free of total dissolved solids. DI water (deionized water) is purified with all ions removed. These ions may include positive ions such as sodium, calcium, iron, copper, and negative ions such as chloride and bromide.

Another aspect of water to think about is the conductivity of it. Water has the ability to conduct an electric current in its normal state. However, when it becomes processed to be RO/DI water, it loses ions that can present any conductivity, which means it is much more safe when going through the humidification process. These types of waters are also perfect in preventing damage to humidification systems, especially from rust, bacteria collection, static energy, and formation of dust in the system.

How Does RODI Water and Ultra Sonic Humidification Work?

As a general overview, ultra sonic humidifiers uses ultrasonic waves to create a fine and cooled mist through cavitation in the water. This process emits a mist that is free of any impurities (ions, vitamins…etc) with the use of RO/DI water. This helps in settings that require pure water cooling to prevent any sort of electrostatic discharge, creation of white dust, and formation of contamination and bacteria – respectively, in data centers, manufacturing, and hospitals/labs.
