What's The Difference Between RO And DI Water Purification?
While it is true that virtually every local water authority must adhere to the strictest federal and state regulations in order to guarantee the security of the water supply, it is also true that they frequently add chemicals like chlorine to attain that degree of security. Yet, drinking water that has been heavily chlorinated is not particularly pleasant.
Although though tap water is safe, it frequently still has pollutants and minerals that leach into the water table. Most water systems have a small amount of potentially harmful pollutants. A water purification system adds an extra layer of safety while also enhancing the taste of your water.
Types of water treatment plants
There are many different types of water filtration systems, such as some fairly straightforward faucet and under-sink filters and residential systems. Each has advantages and disadvantages. To get the purest drinking, bathing, and washing water possible, there are primarily two types of systems:
- reverse osmosis
- Filters for Deionized Water
What is Reverse Osmosis Plant?
One of the most effective and cutting-edge water filtration techniques is reverse osmosis (RO). The majority of known water impurities—up to 95 percent of all dissolved solids—found in urban tap water can be removed by RO, which was originally developed to remove salt from ocean water.
How Does an RO System Work?
There are multiple filtration steps in the RO process. Usually, a pre-cleaning procedure comes first. A pre-filter gets rid of debris like rust and grime. To minimize volatile organic compounds (VOCs), including chlorine and other impurities that give water a poor taste or odor, some systems may also include a carbon filter. Post-filters are what these filters are known as when they are added at the very end of the purifying process. Regardless of whether they are applied during the pre- or post-treatment phases, they are the same kind of filters.
To force water through a reverse osmosis membrane, significant pressure is applied. This membrane is made of a thick polyamide film with minute pores that are just big enough to let water through but not small enough to let organic particles through.
The filtered water is kept in a tank until it is required. When the storage tank is full, the system automatically turns off and restarts when more water is required for storage.
What is Deionization?
Deionized water (DI) is water that has had the ions removed from it, as the name suggests. A particle with a positive or negative charge is referred to as an ion. How do ions form in water?
On the journey to your tap, minerals from the surrounding soil, pipelines, and plumbing water are dissolved. When these minerals dissolve, they bind to the water molecules, which ionizes the molecules and gives them a positive or negative charge.
These ionized mineral particles are prevalent in regular tap water that has not been filtered (which is why DI is also sometimes called demineralized).
How Does a Deionization Water System Work
The electrically charged mineral particles are attracted to and held in place by an ion exchange system made of tiny plastic resin beads. Mineral particles attach to the resin beads as water flows through the beads, cleaning the water and deionizing it before it is sent to a storage tank where it can be used as needed for bathing or drinking.
Sometimes, distilled water is mistaken for deionized water, but they are not the same. Boiling and steaming are used to produce distilled water. While deionized water is more clean than distillate water, the latter can still be ionized.
Conclusion
Deionization has the benefit of softening water in addition to removing impurities. A reverse osmosis system has the advantage of filtering bacteria, viruses, insecticides, and herbicides in addition to other contaminants.
The highest benefits for the health of your family come from a deionized and reverse osmosis system that works together.
