Viqua (Trojan) UVMax F4 UV Sterilizer - #650686

Description, Features & Benefits

Viqua UVMax F4 Series UV sterilizers a popular choice for very large homes with 3 to 6 bathrooms, and light commercial applications. They are designed to treat bacteria (such as e.coli and coliform), viruses, and other microbiological contaminants including giardia (beaver fever) and cryptosporidium without the use of chemicals. They are suitable for the treatment of private wells and surface water supplies, as well as municipal water for those seeking a higher level of confidence in the safety of their water supply. The F4 provides a UV dose of no less than 40 mJ/cm2 for flow rates up to 27 gallons per minute (based on a UVT level of 95% and at the end of lamp life).

Key to the long-standing popularity of the UVMax product line its brand reputation, feature-rich controller, and no-tools maintenance. The high output lamp results in a system with a very compact size relative to its treatment capacity, and its constant current power supply ensures a uniform UV dose even when the source power supply fluctuates. The F4's LCD display ensures all important system information is available at a glance.

UV disinfection is safe, effective, economical, and best of all, does not add undesirable chemicals to your water like chlorine or chloramine.

Not all UV systems are created equally...A good UV sterilizer is far more than a UV lamp in a tube.

Why UV? - UV Advantages

UV water treatment offers many advantages for the treatment of microbiological contaminants like bacteria (including coliform and e.coli), viruses, molds, algae, yeast, and oocysts like cryptosporidium and giardia. Every year, these contaminants are responsible for thousands of serious illnesses due to the failure of city treatment plants or consumption of untreated well or surface water.

Unlike other disinfection options, UV sterilizers do not add any chemicals to the water, do not produce harmful by-products (THMs and HAs), and do not alter the taste, pH, mineral content, or other properties of the water. Accordingly, in addition to producing safe drinking water, UV disinfection is not harmful to your plumbing and septic system. Furthermore, it is easy and cost-effective to install and maintain without any special training.

UV sterilizers are one of the most popular and respected water treatment technologies in use today. They can be found in a wide range of water treatment applications ranging from simple under sink water filters to huge city water treatment plants.

With the infrastructure of cities all over North America crumbling under neglect and budget constraints, many customers have asked us if there was a product that they could add to their water system that would provide them with additional insurance and peace-of-mind against the possibility of a failure of their municipal water treatment system. These concerns have arisen due to several high-profile cases of contamination in city water supplies across the continent, some of which have resulted in illness and even death. UV disinfection is a great option to provide this extra level of insurance in your water supply.

Pre-Treatment Requirements

Minimum pre-filtration shall consist of a 5 micron sediment filter. All UV sterilizers require sediment pre-filtration to reduce or eliminate the possibility that a targeted contaminant could "hide" behind a sediment particle in the "shadow" of the UV light and therefore not receive a full dose of UV light. Accordingly, the manufacturer strongly recommends sediment pre-filtration down to a level of 5 microns or smaller.

Water exceeding 120 ppm in hardness (7 grains per gallon) should be softened or treated with a salt-free hard water conditioner to reduce the risk that hard water mineral scale will build-up on the UV sleeve thereby reducing UV light distribution into the UV chamber. Similarly, iron levels exceeding 0.3 ppm or manganese levels exceeding 0.05 ppm should also be treated to prevent staining of the UV sleeve.

Elevated levels of certain other contaminants, such as tannins, can cause a reduction in UV transmittance (the ability of the water to transmit UV light). If the UV transmittance (UVT) of your water is less than 75% after the above-mentioned pre-treatment, activated carbon filtration may be desirable to improve UV transmittance. The majority of deep wells have a UVT of 85% or greater. If your UVT is unknown, select a model with a higher flow rate capacity than the one you originally sized at 95% UVT (this will provide a higher UV dose at your desired flow rate), or add an activated carbon pre-filter to your system.

We recommend that you have your water tested for the following parameters before selecting a UV sterilizer. Proper pre-treatment to ensure that your water meets these parameters will maximize the performance of your UV system. It will also reduce your maintenance requirements. If your conditions do not meet these parameters, please call us toll free at 1-866-376-2690 to discuss pre-treatment options or to discuss how the performance of your UV system will be affected.

How Ultraviolet (UV) Disinfection Works

UV sterilizers are an innovative technology that deactivate bacteria, viruses, and other microbiological water contaminants without the use of chemicals.

A great way to understand a UV sterilizer is to consider the effect of ordinary sunlight when we spend too much time outdoors in the sun - we can get a sunburn and our skin can be damaged. UV water disinfection is a similar process, except that it is dramatically more powerful than sunlight. A special lamp, surrounded by a quartz glass sleeve inside the stainless steel chamber that the water flows through, produces concentrated UV light at a specific wavelength tested to be the most damaging to microorganisms. Inside the chamber, the microbes are exposed to the UV light which damages their DNA. Once the DNA of the organism is damaged, the microorganism is unable to regulate its functions and reproduce. It either dies or is no longer able to reproduce and cause illness. We call this inactivation.

Just as the extent of your sunburn can vary depending on how much time you spend in the sun and the intensity of the sunlight, the amount of UV light the contaminants are exposed to determines the effectiveness of the UV sterilizer. This is known as the UV dose. The 2 factors that contribute to UV dose are the exposure time (which is directly related to the flow rate of the water through the UV chamber), and the intensity of the UV light (related to the effectiveness and design of the UV lamp and chamber, the age of the lamp, the clarity of the sleeve, and the clarity of the water being treated). We refer to the clarity of the water as UV transmittance or UVT. It is important to note that water with a high level of organics can sometimes appear virtually clear but have poor UVT (since many organics can absorb UV light). We recommend that you have the UVT of your water tested to ensure you are getting the right level of UV treatment.

UV Dose = UV Intensity x Exposure Time (Flow Rate)

To ensure a high UV intensity, it is important that the UV sleeve be cleaned periodically and that the water is properly pre-treated to remove minerals that can foul the UV sleeve (hardness, iron, and manganese). It is also important to pre-treat to remove sediment as well as organics and tannins that could absorb UV light. Pre-filtration of sediment to a minimum level of 5 microns is required by all UV manufacturers.

As a UV lamp ages, the intensity of the UV light it produces will decline. UV manufacturers test the performance of their UV systems to ensure that they are capable of safely treating the water based on the UV output of their lamp at the end of its stated life. Beyond this point, the UV lamp might still be illuminated, but the specific wavelength of UV light might not be intense enough to safely sterilize the water. This is why it is very important to replace the UV lamp based on the manufacturer's stated lamp life. Most UV lamps have a service life of 9,000 hours or 1 year.

Many of our competitors advertise the capacity of their UV sterilizers based on a dosage of 30 mJ/cm2. We provide this information for comparative purposes, however, we strongly recommend that you size your UV sterilizer based on a dosage of 40 mJ/cm2. This ensures better disinfection when the UVT is less than optimal and provides extra protection against more resistant viruses. See our UV dose chart for a list of UV dosage levels required to treat for common bacteria and other waterborne pathogens.

With proper pre-treatment and scheduled lamp replacement, UV disinfection is a highly effective and economical means of disinfecting drinking water. It is the most popular disinfection technology for well water and other private water supplies. It is also growing in popularity as a whole house treatment for homes connected to a city water supply as homeowners seek additional assurance that their water supply is safe, especially in light of recent prominent infrastructure failures in the news across the country.

Installation, Manuals & Resources

We recommend that UV sterilizers be installed by a licensed plumber; however, your warranty is valid as long as your system is installed in accordance with local plumbing codes and the manufacturer's Owner's Manual. For a homeowner with basic plumbing experience, the installation of a UV sterilizer is relatively simple.

We generally recommend that all UV sterilizers be installed with the treatment chamber in a vertical position, however, it is acceptable to install the UVMax F4 horizontally. You will need access to a nearby standard electrical outlet to power the unit.
