The safety of drinking water has received more attention than ever, water
purification, therefore, has become an important factor for people to improve their quality of life. In the
water purification
industry, there are also places where ozone plays a role.
What is ozone water treatment?
Ozone is also known as trioxygen and its chemical formula is with O3. It consists
of three oxygen atoms.
When dissolve in water, Ozone is an oxidant with extremely superior performance. It
can oxidatively decompose the difficult-to-degrade organic matter in the water body, and cooperate with other
processes to achieve advanced treatment of wastewater. This process is known as direct oxidation, which is slow
and has certain limitations where ozone molecules can only interact with organic pollutants or metal ions
containing unsaturated bonds in water.
Another way is indirect oxidation. The partial decomposition of ozone produces
hydroxyl radicals and the interaction of organic matter in water. The indirect oxidation reaction is quite fast,
non-selective, and can react with a variety of pollutants.
How does ozone water treatment work?
Ozone is not stable under normal
atmospheric conditions, which means in commercial applications, ozone must be on-site using an ozone generator.
The lifetime of ozone in water depends on various factors, including water temperature, ozone concentration, and
the composition of the water itself.
The ozone generator is the process of converting oxygen into ozone by using high
voltage discharge. The high-voltage alternating current is applied to the high-voltage electrode with an
insulator and a certain gap in the middle, therefore, the dried and purified air or oxygen can pass through.
In most commercial applications, ozone is produced by
passing an oxygen-containing gas through an electric
field formed between two electrodes. When the oxygen molecules in the gas interact with the electric field, the
oxygen molecules are dissociated and recombined, forming ozone. This process is the so-called corona discharge
ozone generation method.
What do ozone water treatment systems remove from water?
Ozone is one of the strongest disinfectants used in water treatment. Water that
goes through ozone water treatment is free of viruses, parasites, bacteria, and fungi. All these impurities are
removed when the ozonation process takes place.
Ozone also inactivates yeast and parasites. It is one of the strongest oxidants on
the market, which is 50% more efficient than chlorine in terms of disinfection, making it one of the most
powerful solutions to municipal, industrial and commercial water treatments.
What are the benefits of ozone water
Simple treatment process
Ozone water treatment requires no additional chemicals to be added to the water
during treatment. The treatment removes many impurities from the water as well as odor and taste. Compared to
chlorine, ozonation is considered to be more effective than chlorination regardless of the pH level of the
water.
Strengthen body systems
From a health perspective, ozone water can: boost your immune system, reduce the
amount of acute inflammation you suffer, clear viruses immediately upon contact, break down synthetic chemicals,
purify the blood of harmful cells, potentially reduce cancer cells while slowing tumor growth, and send more
oxygen to facilitate brain function.
If you have suffered from rheumatoid arthritis or inflammatory bowel disease, ozone
water offers a reduction in inflammation that can help you cope with these conditions. Because ozone water kills
viruses immediately upon exposure, it can help you avoid catching viruses such as the flu or even coronavirus.
What are the disadvantages of ozone water
Though ozone is powerful in sterilization and disinfection, water ozonation also
has a number of limitations that you should take into account.
High cost
Ozonation is relatively expensive to operate. The Ozonation equipment is costly and
requires ongoing maintenance.
Skillful technique
Ozone is not as soluble as chlorine, which means special mixing techniques are
required so that ozone gas can be dissolved properly. The ozonation does not leave residual disinfecting
elements, so there would be chances for the regeneration of bacteria or viruses.
High risk
Ozone is a toxic gas, meaning that ozone production can cause fire hazards and
toxicity problems. The system may require prior treatment to reduce some of the hardness in the water, which
helps prevent the formation of carbonate scale. The by-products of ozonation are still under scientific research
for their potential carcinogenicity.
What is the best water filter for home
Now we’ve learned the pros and cons of ozone water treatment, you may have a
question regarding an ideal water purification method for home use. If you would like some hassle-free ways, we
recommend using water filtration systems like reverse osmosis and ultrafiltration to easily access safe drinking
water.
Reverse Osmosis
Reverse osmosis technology follows an underlying principle – there is a separation
of water and other substances in a solution when the solution is forced through a semi-permeable membrane by a
pressure higher than the osmotic pressure of the solution. Separation occurs because the molecules of these
foreign substances are too big to pass through the pores of the reverse osmosis membrane. The size of these
pores is about 0.0001 microns; therefore, the membrane effectively separates organic matter, microorganisms,
colloids, and dissolved salts from water molecules.
Waterdrop G2MNR Remineralization Reverse Osmosis Water Filter
The Waterdrop G2
undersink reverse osmosis
mineralization system is designed to reduce most impurities in water effectively. It is equipped with an
external RO remineralization filter, which re-adds useful minerals to the filtered water. The RO system
separates harmful substances from the water molecules and adds the beneficial trace minerals the body needs to
function effectively. Overall, it delivers safe and healthy drinking water.
Ultrafiltration
Ultrafiltration (UF) technology is somewhere in-between microfiltration and
nanofiltration. It is a special membrane separation technology that can purify, separate, and concentrate
solutions, thanks to the membrane's 3-100 nm average pore sizes.
Ultrafiltration Under Sink Water Filter System Waterdrop TSU-B
Unlike the GP300, the TSU-B is a better value for its price. You get an
ultrafiltration system that can effectively remove various contaminants in water, including sediment, suspended
solids, rust, colloids, and bacteria. It also filters off macromolecular organic matter, which is known to be
larger than bacteria.
