    Knowledge Zone and FAQ

    Here are some of the most common question about VIQUA Water Filters and UV-disinfection.

    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.

    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, we offer all our Hua Hin customers installation and maintenance of VIQUA systems. With our scheduled maintenance program, we will visit to check your system and maintain it as needed.

    The disinfection process has 3 steps. First the water passes a 5 Micron sediment filter that rids the water of dirt, particles and sediment. Then the water reaches a carbon filter that takes care of any unwanted taste and smell.

    Finally, the water reaches the heart of the system and the most important part of the treatment process – the UV-disinfection chamber. Here the water flows past a high-output UV-lamp that immediately kills any harmful microbes and bacteria present in the water. The water exiting the system is now perfectly safe to drink.

     

    A sediment filter and a carbon filter is necessary for the water to be clean and clear enough for the UV-light to be able to penetrate the water and effectively disinfect it from microbiological contaminations.

    It is pretty simple. The UV lamp needs to be replaced every 365 days and the pre-filters every 4-12 months depending on the water quality in your area and usage.

    The Whole Home Systems has a control unit that indicates remaining lifetime of the lamp and will let you know when it is time to replace it.

    For the pre-filters a slight drop in water pressure is usually a sign that the filters are getting clogged up and needs replacing.

    Also, we keep in touch with all customers on a regular basis to make sure that their systems are working properly.

    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.

    We offer different models of systems to suit the different water flow demands of our customers. For example, our Whole Home Systems ranges in capacity between 40-70 liters per minute and our Multi Point Filters 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.

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

    No. A VIQUA system can be installed without a water pump. However, most of our customers already have a pump installed or choose to install one to get better water pressure in the house. The VIQUA system itself will not restrict the water pressure.

    VIQUA systems connects to a wall outlet like other electrical appliances. VIQUA 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.

    Yes, we do. Stainless steel chambers are warranted against leakage due to manufacturing defect for 10 years. System controllers are warranted against manufacturing defect for 3 years. UV lamps and quartz sleeves are covered for 12 months.

    Yes you can. However, in many areas of Thailand, well-water means hard water or a lot of iron or other substances in the water. In these cases we always recommend our customers to speak to a 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 VIQUA system.

    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.
