Why choose a water filter with UV-disinfection?

UV disinfection of water has a long and well-proven history and is installed in many public drinking water treatment plants all over the world, for example in New York City. Discover this video that explains more about the history and technology of UV water disinfection.

How is a UV Purification system different from a Reverse Osmosis system?

What our customers say

"My wife and I purchased a VIQUA Whole House water filter system in July 2018, on the recommendation of friends in the same village who are very happy with it. It was important for us to have perfect tap water for cooking and personal hygiene. This expectation was fully fulfilled. The maintenance of the system is quite simple. In addition, the service of Kat-Tech Engineering is fast and reliable."

Common questions about our water filters and Hua Hin water quality

Yes we do.

Yes, we offer all our Hua Hin customers installation and maintenance of our water filter systems. With our scheduled maintenance program, we will visit to check your system and maintain it as needed. Contact us to schedule a free survey and quote.

This varies greatly depending on where in the Hua Hin area you are located. Some areas experience severe problems with the water distribution pipes that causes contamination and very dirty water. In other areas, especially when connected to the Pranburi water line, the water quality is good, but due to contaminations in the water pipe system, still not safe to drink when it reaches our homes.

Often times broken main water pipes, especially during rain season will cause contaminations to enter the water distribution system.

If you use your own well we recommend you to perform a water test to find out more about the water quality from your water source.

Yes, absolutely. In fact, municipal water in Thailand is generally perfectly safe to drink when it leaves the water treatment facility. The problem is the vast network of water pipes with often poor quality that the water has to pass before it reaches our homes. This is where the water easily get contaminated by bacteria and harmful microbes.

With a UV-disinfection system that effectively eliminates these contaminations, the water is then again perfectly safe to drink.

Our systems connects to a wall outlet like other electrical appliances. The systems should always be connected to a dedicated wall outlet protected by a GFI (ground fault interrupter) /RCD. In areas that experience significant power fluctuation, we recommend the use of a surge protector.

A UV-lamp has a lifetime of 365 days of continuous use. After that, the UV-light intensity starts to diminish and it is no longer able to effectively disinfect the water. It is very important to replace the UV-lamp every 365 days to ensure that your water is still safe to drink. Our Whole Home Systems have a sophisticated control unit that will let you know the status of the system. It tells you how many days are left until lamp replacement and will give you a visual and audible alarm when the the lamp life is due to replacement.

UV lamps have a useful life of about 9000 hours (approximately 365 days) which means that in most cases annual replacement is required. It is very important to replace the UV-lamp after 9000 hours, since there may not be enough UV energy to provide adequate disinfection after that.

There is also a quartz sleeve that surrounds the UV lamp which must be kept free from hardness or iron deposits that would have a negative impact on the UV disinfection process. Under normal conditions the sleeve can be cleaned when doing the annual lamp replacement.

For our Whole House and Point of Use Systems that comes complete with pre-filters (sediment and carbon) maintenance includes replacing these when they get dirty or clogged. Replacement interval for pre-filters depends on usage and water quality in your local area and can vary from between 5-12 months.

Municipalities work very hard to provide safe water for their customers. In some areas of Thailand, the water leaving the treatment plant is considered safe to drink. However, that water then moves through a vast distribution system that in many cases is aged and can lead to contaminations. The water that then reaches your home is often far from safe to drink. A UV Disinfection System gives you and your family peace of mind and is a very affordable insurance policy against the possibility of coming in contact with water contaminated with microbes.

Yes you can. However, in many areas of Thailand, well-water means hard water or a lot of iron, manganese or other substances in the water. In these cases we always recommend our customers to speak to us, our local partner or another local water treatment company first to get accurate information about water quality in the local area and advice on whether additional treatment is needed before installing the system.

No.The systems can be installed without a water pump if the mains water pressure is high enough in your area. However, most of our customers already have a pump installed or choose to install one to get better water pressure in the house.

No. UV Systems are designed with correctly sized inlet/outlet for the specific application.

VIQUA offers different models of systems to suit the different water flow demands of our customers. For example, our Whole House Systems ranges in capacity between 40-70 liters per minute and our Point of Use systems ranges between 7-24 liters per minute.

The size you need depends on the size of your home (how many bathrooms, kitchens, showers etc.) and the size of your family. As a reference a bathroom tap typically have a flow rate of 4-8 l/min and shower head between 10-15 l/min.

If you have a water pump installed it is good to determine the maximum flow rate of the water pump to then determine the VIQUA system best suited to that flow rate.

It is very important to not undersize the UV system, since a flow rate that exceeds the max capacity of the UV-system means that the water will not get enough exposure to UV-light needed to ensure adequate disinfection. If in doubt, it is always better to choose the next largest size of UV-system.

The ultraviolet (UV) treatment process is an extremely quick physical process. Ultraviolet light mutates and/or degrades DNA. DNA (or deoxyribonucleic acid) is the part of the cell that gives an organism its instructions on how to function and reproduce.

When the DNA is damaged, the organism becomes unable to function because its “instructions” are garbled or missing. An organism that has no instructions cannot function and reproduce, and cannot cause infection. It is rendered harmless and eventually dies.

In the UV disinfection process, water is purified as it runs through a stainless steel chamber (also called a “reactor”) that contains a special UV- producing lamp. As the water flows past the lamp, the microbes in the water receive a lethal dose of UV. The water is then safe to drink.

UV disinfection typically offers a 4-log reduction (99.99%) for both bacteria and most viruses. UV is more effective than chemical disinfection processes at destroying a wide range of viruses.

We look forward to hearing from you and discuss water filter solutions with you
