The Ultimate FAQ Guide for Ultraviolet (UV) Water Filter For Home.

Viruses, bacteria, and other pathogenic microbes may find their way into virtually any home water supply line. This often happens at the source or as the water is piped to your home. Water infected with microbial pollutants exposes human beings and animals to serious waterborne illnesses. To avert the contraction and transmission of waterborne diseases, most households are incorporating water sterilization units into their home water treatment systems. Ultraviolet water filters are some of the most effective and well-reputable water disinfection systems. Underneath, we will be extensively covering UV water filters for homes, their working principles, and operational specifications.

➣What is a UV Water Filter For Home?

A home ultraviolet (UV) water filter is a water disinfection device installed in homes to get rid of bacteria, viruses, and other pathogens. UV water sterilizers have become more prominent in recent years thanks to their low operational costs, unmatched kill rate, and ease of use. Unlike other water disinfection technologies e.g. chlorination, UV water filtration hardly uses chemicals. This technology exploits germicidal radiation to inactivate harmful microbial pollutants.

A typical home UV water filter treating high-quality feedwater guarantees a microbial removal rate of 99.99%. In most applications, UV water sterilizers are however employed in conjunction with other water filtration systems. Optimum disinfection can only be achieved after certain impurities e.g. hardness-causing minerals, iron, and suspended solids have been extracted. This is because most of these constituents shield the microbes thereby blocking the reach of the germicidal rays.

Conventional UV water filters ordinarily operate at a wavelength of approximately 253.7 nanometers. This wavelength is safe and can inactivate virtually all microbial pathogens. We manufacture custom-made UV water sterilizers characterized by impeccable kill rates, ease of use, cost-efficiency, and longevity.

➣What Are the Chief Benefits of Home UV Water Filters?

In industrial, commercial, and residential water purification applications, UV water sterilization systems are slowly taking over. This is primarily a consequence of their affordable investment and operational costs as well as their outstanding disinfection rate (up to 99.99%). Below, we briefly discuss the primary rewards realized when using home UV water filters.

●      Optimal removal of microbes.

A typical UV water filter for home will comfortably destroy 99.99% of the viruses, bacteria, and other pathogens present in your feed water. This is accomplished using germicidal rays at a wavelength of 253.7 nm. UV water sterilizers inactivate nearly all if not all waterborne microorganisms.

●      Low operational costs.

They typically necessitate low power to function optimally. In addition, they hardly necessitate manpower or chemical disinfectants. This makes them relatively cheaper to operate compared to chlorination or ozonation.

●      Low contact time.

With a UV water filter for home, it will only take you less than 10 seconds to sterilize your water. The process of UV water disinfection is quite fast compared to other processes like chlorination, which needs a contact time of 20-30 minutes.

●      Chemical-free.

Ultraviolet disinfection is a chemical-free process that utilizes germicidal radiation to inactivate microbes. This means that the risk of under-dosing or overdosing is averted and that the user is safe. Additionally, filtered water retains its authentic taste and odor.

●      Environmentally friendly.

By hardly utilizing chemicals, UV water filters hardly emit toxic waste capable of degrading the ecosystem and its inhabitants. This is particularly important given that the world is presently suffering from adverse climate change caused by environmental pollution.

➣How Do Ultraviolet Water Filters for Home Function?

Ultraviolet water sterilization is an elaborate water purification process that primarily inactivates bacteria, viruses, and other microbes using germicidal rays. The feed water is essentially passed through a reactor chamber housing a UV lamp enclosed in a quartz sleeve. However, before the feed water is directed into the reactor chamber, it is first pre-filtered to remove suspended solids, turbidity, hardness, and other constituents.

As the water passes through the reactor chamber, it is exposed to germicidal rays or spectrum emanating from the UV lamps. Conventional home water UV filters necessitate a UV frequency of approximately 254 nanometers to optimally disinfect raw water. The germicidal rays penetrate through the microorganisms and attack their genetic codes. They destroy the microorganism’s nucleic acid and disarrange its DNA/RNA cells.

Consequently, the microbe’s ability to reproduce or grow is curtailed. Technically, UV water sterilization inactivates microbial pathogens. The water leaving the UV water filter is essentially devoid of bacteria, fungi, algae, and viruses among other pathogenic microbes. The underlying video demonstrates how to install a UV home water filter and how ultraviolet sterilization functions.

➣Is Pretreatment Needed When Using UV Water Filters for Homes?

For household UV water filters to be effective, the germicidal rays must be allowed to reach all the waterborne microbes. The presence of other impurities in the feed water may curtail the reach of the germicidal radiation thereby decreasing the range of microbial pathogens inactivated.

Some of these impurities include suspended solids, which act as shields that protect the microbes from UV rays, and iron, which absorbs germicidal radiation. To attain optimal results, ensure that your feed water has the following qualities.

Here is a brief discussion of the various pretreatment systems that can help you precondition your UV water sterilizer feed water.

●      5-10 micron filters.

The feedwater entering the UV water filter must have a maximum TSS level of 10 mg/L. This is because suspended solids block the penetration of germicidal rays thereby hindering the disinfection process. With a 5-to-micron filter, dust particles, floating solids, and debris are filtered out thereby facilitating optimal filtration.

●      Water softeners.

Varying types of water softener systems can be deployed to extract hardness-causing minerals i.e. calcium (Ca2+) and magnesium (Mg2+). However, ion exchange softeners and nanofiltration systems are the most prominent. They help bring down the hardness levels to 7 grains per gallon or lower.

●      Reverse osmosis systems.

Reverse osmosis systems are membrane-based water treatment systems known for extracting a plethora of undesirable contaminants. Quite often, household RO systems eradicate dissolved solids (TDS), minerals, organic compounds, nitrates, and certain microbial pathogens. In most home water purification set-ups, UV water sterilizers are deployed as post-treatment systems for reverse osmosis systems. Other usable pretreatment systems include;

• Chemical dosing systems.
• Iron removal filters.
• Multimedia filters.
• Activated carbon filters.
• Ultrafiltration filter systems.

➣What Are UV Water Filters for Home Made of?

Ultraviolet water filters for homes are simply designed and compact. They are however made up of different interconnected components, which work in tandem as a cohesive unit. For a user or owner, it is important to understand the varying components of a UV sterilizer so as to understand how you can get the best out of your system. Here is a brief breakdown of conventional home UV water filters.

●      The UV chamber.

The UV chamber or the reactor chamber is a long cylindrical vessel that accommodates the other components of the UV filter. The held components include the UV lamp and the quartz sleeve. Moreover, the UV chamber consists of the inlet and outlet faucets. Most UV chambers are made of stainless steel, which makes them highly resistant to corrosion and extremely durable.

●      The ballast.

The ballast is also known as the control unit and it is simply the command station of the UV water filter. The primary role of the ballast is to regulate the UV lamp’s electrical output. Different UV sterilizers are endowed with ballasts characterized by differences in size, design, and complexity.

●      The Ultraviolet (UV) lamp.

The UV lamp is a bulb-like lamp that discharges the UV-C light needed to inactivate microbial pathogens. UV water sterilizers can be equipped with either of the following UV lamps; standard, amalgam, or high-output UV lamps. Most UV water sterilizers are endowed with UV lamps whose lamp intensity ranges from 30,000 to 50,000 µWatt•sec/cm²

●      Quartz sleeve.

The quartz sleeve is a glass, cylindrical tube that encloses the UV lamp. The quartz sleeve is made of glass to allow the passage of the germicidal rays produced by the UV lamp. Over time, foreign constituents may build up on the quartz sleeve thereby necessitating cleaning.

●      The UV sensor.

Most contemporary home UV water filters now include a UV sensor. This is a device that keeps track of the UV lamp’s intensity. Once the intensity depreciates significantly, the UV sensor triggers an alarm to notify the user.

➣How Does Ultraviolet Sterilization Compare to Other Water Disinfection Processes?

UV water sterilization is inarguably one of the most revered and effective water disinfection technologies. Other high-level disinfection technologies include chlorination, ozone disinfection, and nanofiltration. Underneath, we look at some of the most popular alternatives to UV water sterilization, their working principles, and how they compare to UV sterilization.

●      Chlorination.

Chlorination is one of the oldest and most commonly used water sterilization technologies. Essentially, chlorine or chlorine compounds are administered into raw water to destroy or kill waterborne microorganisms. Some of the chlorine compounds used to disinfect water include sodium hypochlorite and chloramines. This process kills nearly all bacteria, viruses, and pathogens. A contact time of approximately 20-30 minutes is necessitated to optimally disinfect the water.

●      Ozone disinfection.

Ozone disinfection gets rid of biological impurities like viruses and bacteria using the strength of ozone oxidation. Ozone is first generated using ozone generators before being administered into the feed water. The ozone then oxidizes the waterborne microorganisms consequently ripping them apart and killing their cells. Ozone disinfection requires a contact time of approximately 10-20 minutes.

➣How Long Does It Take UV Water Filters for Home to Disinfect Water?

The amount of time taken to disinfect the water using germicidal radiation provided by the UV lamp is commonly referred to as the contact time or residence time. For home UV water filters, a contact time of approximately <10 seconds is needed to generate filtered water devoid of microbial pathogens. This is mind-boggling, to say the least, given that other sterilization processes like chlorination take 20-30 minutes while ozone disinfection takes 10-20 minutes.

It is worth noting that the contact time needed to fully disinfect water depends on various factors such as the UV dose and the concentration of other impurities. UV dose is typically expressed or indicated as 1mJ/cm2=1000 microWatt second/cm2. Microbes that necessitate low UV doses (1-10 mJ/cm2) include Giardia lamblia and cryptosporidium Parvum. Microbes that necessitate high UV doses (30-150 mJ/cm2) include enteric viruses.

➣Which Maintenance Practices Do UV Water Filters for Home Necessitate?

To ensure that your home UV water filter continues to function like a brand new system, you must adhere to the maintenance practices and routines provided by the manufacturer. Maintaining a UV water filter for home is generally easy and quite inexpensive. Underneath are some of the maintenance practices your UV water sterilizer needs.

●      Cleaning of the quartz sleeve.

Objectionable impurities present in the feedwater may accumulate on the quartz sleeve consequently leaving a film of dirt. This layer of dirt can shield the passage of germicidal radiation thereby making the UV sterilization process ineffective. Clean the quartz sleeve every time you change the UV lamp.

●      UV lamp replacement.

The UV lamp is the primary component in UV water sterilizers. Ordinarily, UV lamps comprise mercury, which depreciates over time. This leads to lower light intensities and ineffective water sterilization. Typical UV lamps have a life expectancy of approximately 9,000 hours hence they must be substituted after 12 months.

●      Quartz sleeve replacement.

Unlike UV lamps, the quartz sleeve has a life expectancy of approximately 2 years. This means that you should replace your quartz sleeve after every 24 months to avoid subpar performances. Extensive guidelines on the proper use and maintenance of homUV water filters are provided in our user manual.
