    The Ultimate FAQ Guide for Ultraviolet Disinfection Units

    Safe and purified water is extremely essential in safeguarding public health across the globe. Biologically contaminated water is responsible for millions of deaths annually arising from waterborne illnesses like diarrhea, typhoid, and cholera. The good news is that these pathogenic microorganisms responsible for causing and transmitting these devastating illnesses can be extracted from the water before they can cause any harm. This is primarily a consequence of advanced water purification technologies such as ultraviolet sterilization and chlorination. In our article today, we are mainly going to focus on ultraviolet(UV) disinfection units, how they work and why you need them.

    Figure 1 Ultraviolet disinfection unit.

    What is an Ultraviolet Disinfection Unit?

    An ultraviolet (UV) disinfection unit is a water purification machine designed to inactivate bacteria, viruses, and other pathogens using germicidal rays. The UV water purification system does not necessarily extract the microbial pathogens; it simply deactivates them by destroying their genetic makeup. Their effectiveness is constrained to living microorganisms’ removal hence they are often deployed as supplemental water purification systems.

    UV water sterilizers hardly necessitate chemicals to disinfect water. This results in purified water that still has its authentic taste and odor. The germicidal radiation they exploit is often at a wavelength range of 253.7 nanometers, which facilitates the inactivation of 99.99% of the harbored pathogens. Additionally, the range of microbial pollutants inactivated using UV water disinfection is unlimited.

    In the recent past, the use of ultraviolet disinfection units has proliferated tremendously. They are gradually replacing the use of chlorination and most municipalities have now incorporated them into their water purification plants. NEWater manufactures certified UV water disinfection units customized for industrial, household, and commercial applications in line with ISO 9001 guidelines.

    What is the Role of a UV Unit?

    Ultraviolet disinfection units are mainly deployed in the final stage of water purification to get rid of any remaining bacteria, viruses, or pathogens. The primary role of UV disinfectants is to shrink the microbial count in water. They can be deployed in distinct applications to eliminate the threat of microbial contamination. For instance, a UV disinfection unit for households can be installed at the point of entry or point of use to eliminate viruses and bacteria consequently generating safe drinking water.

    In addition, they can be used in commercial enterprises such as commercial water bottling to purify the water. UV water purification systems are also commonly exploited in wastewater treatment, particularly in the post-treatment phase. Their specialization in extracting microbial contamination means that they are often deployed to supplement other purification systems. However, they can be deployed as standalone units depending on the range of pollutants harbored by the feed water. Microbial contaminants eliminated by UV disinfection systems include;

    • Viruses.
    • Bacteria.
    • Cryptosporidium.
    • Giardia.
    • Fungi.
    • Algae.
    • E. coli.

    What is the Working Principle of Ultraviolet Disinfection Units?

    The water purification technology utilized by ultraviolet disinfection(UV) units are universally referred to as ultraviolet water sterilization. Contrary to water chlorination, UV sterilization hardly relies on chemicals. It utilizes germicidal radiation to impede the reproduction and functionality of microbial pathogens. Quite often, the process of UV water sterilization commences with pretreatment. The feedwater is first passed through 5 to 20-micron water filters or ultrafiltration filters to extract suspended solids, which might interfere with the transmission of the germicidal rays.

    Consequently, the pretreated water is injected into the reactor chamber of the UV disinfection unit. Here, the microorganisms are exposed to UV-C light emanating from the UV lamp at intensities of 16,000-50,000 µWatt•sec/cm². The germicidal radiation modifies the nucleic acid found in the microbes’ DNA cells thereby mitigating further reproduction. Different pathogenic microbes are inactivated at varying UV light intensities. For instance, coliform bacteria are completely inactivated at a light intensity of 7,000 µWatt•sec/cm².

    However, most ultraviolet disinfection units are endowed with UV lamps characterized by light intensities ranging from 30,000 to 50,000 µWatt•sec/cm². Under this range and at a UV wavelength of 253.7 nm, virtually all microbial contaminants are killed. The underlying video outlines how a typical UV disinfection unit functions.

    Which Types of Ultraviolet Lamps Are Used in UV Disinfection Units?

    The ultraviolet lamp is unquestionably the most pivotal component of UV disinfection systems. They are endowed with mercury, which is evaporated by filaments to generate germicidal rays. Typical ultraviolet disinfection units are equipped with UV lamps of light intensities ranging from 30,000-50,000 µWatt•sec/cm². Underneath, we briefly look at the three types of UV lamps used in ultraviolet disinfection units.

    ● Standard ultraviolet lamps.

    Standard ultraviolet lamps are essentially low-pressure lamps fitted in UV water sterilizers for households. The majority of standard UV lamps have the capacity to generate ultraviolet radiation doses of 50 to 150 mJ/cm2. This UV dose is capable of inactivating all microbial pollutants found in your feed water. Standard UV lamps are the most utilized UV lamps in water sterilization.

    ● High output ultraviolet lamps.

    High-output ultraviolet lamps are technically low-pressure UV lamps specially designed to function at higher UV output. Higher UV-C output is generated by optimizing pressure and gas mixing. The size and shape of high-output UV lamps are quite similar to that of standard UV lamps. They are ideal for applications dealing with moderate or enormous water capacities.

    ● Amalgam ultraviolet lamps.

    Amalgam UV lamps ideally utilize vaporized mercury to intensify the potency of ultraviolet radiation. Compared to traditional standard UV lamps, their UV power density can be up to 10 times stronger. Moreover, amalgam UV lamps can tolerate ambient temperatures as high as 90°C and are immune to temperature oscillations. They are primarily used in ultraviolet disinfection units for commercial applications.

    What Conditions Must Feed Water for Ultraviolet Disinfection Units Meet?

    For the germicidal UV-C rays to be effective, they must effectively come into contact with the waterborne microbes. Feedwater containing other contaminants lessens the effectiveness of the UV disinfection unit. Objectionable constituents such as iron-dissolved organics and inorganics can absorb the germicidal rays or cover the objectionable microbes thereby shrinking the effectiveness of UV sterilization.

    The feedwater must be clear with a turbidity range of 5 NTU or lower. A higher turbidity level may make the feed water unclear thereby blocking the reach of the UV rays. The incoming water should have a maximum TSS level of 10 mg/L. This can be accomplished by pretreating the feed water using a 5to 10-micron filter. Excessive concentrations of iron can absorb the germicidal radiation hence the need for an ion exchange system or an iron removal filter.

    The maximum iron content should not exceed 0.3mg/L while the magnesium level should be within <0.05 mg/L. As for the acidity levels, the feed water must exhibit a pH ranging between 6.5 and 9.5. Ideally, ultraviolet disinfection units are frequently deployed in the post-treatment phase.

    Which Factors Should I Consider When Purchasing an Ultraviolet Disinfection Unit?

    Purchasing the ideal ultraviolet water purification system should not be a cause of concern for you. At NEWater, we provide prospective buyers with all the aid and resources they need to procure the best system. In the following excerpt, we discuss some of the primary factors you should deliberate on before investing in a UV water filter system.

    ● The raw water quality.

    For a UV water purifier to function optimally, the feed water must be devoid of inorganic constituents like iron, turbidity, and suspended solids. Assess your imminent feed water to establish the range and concentration of harbored impurities. The feed water quality should also help you in selecting the ideal pretreatment system if necessary.

    ● The ultraviolet (UV) dose.

    The UV dose refers to the output of UV energy transmitted by the UV lamp to the feed water. Ordinarily, UV dose is expressed as mJ/cm2 and it influences the type of microbial pathogens inactivated. For instance, if your feed water has cryptosporidium and E. coli, your UV disinfection unit should support a UV dose of 10 mJ/cm2. Other microbial pathogens might necessitate higher UV doses for example rotavirus SA11 and Poliovirus Type 1.

    ● The flow rate.

    The flow rate reflects the amount of water the ultraviolet disinfection unit can disinfect over a certain timeline. It measures the rate at which feed water enters and exits the UV sterilizer. Typical UV disinfection units have flow rates ranging from 0.5 GPM to over 2000 GPM. For households, you might need a sterilizer with a flow rate of 5 GPM to 20 GPM depending on your quantity demands.

    Back to the guide ⇪

    How Can I Properly Maintain my Ultraviolet Disinfection Unit?

    Ultraviolet disinfection units are like any other essential apparatus; they necessitate frequent and high-level maintenance to function optimally over extended periods. The shell housing of the UV lamp must be regularly cleaned to ensure germicidal rays reach the microbes effectively. The housing or quartz sleeve should be replaced after two to three years of use.

    Cleaning should be carefully carried out using solutions of citric acid or sodium hydrosulfite (at a concentration of 0.15%). After shutting down the ultraviolet disinfection unit, you should cleanse the plumbing system to get rid of the amassed pollutants. In addition, you should allow for a UV lamp warm-up before reusing the system again. The entire UV water sterilizer and your plumbing system should be sterilized using chemicals like chlorine.

    Ultraviolet lamps tend to depreciate in intensity over a specific period of time. In fact, the intensity of a UV lamp can depreciate by 20% within 100 hours of use. Higher intensity is however maintained in the following hours (up to 9,000 hours). This means you should substitute the worn-out lamps after approximately 12 months if your system runs for the whole day.

    Which Pretreatment Technologies Supplement the Best UV Disinfection Units?

    Disinfecting feed water comprising dissolved organic and inorganic compounds like iron and suspended solids using ultraviolet water filters can be quite difficult. These constituents may absorb the UV-C radiation meant to inactivate the microorganisms or shield the microbes from the reach of germicidal radiation. Below, we look at some of the best pretreatment processes for ultraviolet disinfection units.

    ● Media filtration.

    Impurities such as dust particles, microplastics, and other floating solids can be extracted using media filters such as pressure sand filters. For UV water sterilization systems, it is recommended that 5 to 20-micron filters be deployed to pretreat the feed water. Media filtration systems also lessen the turbidity levels, which is important in UV water sterilization.

    ● Reverse osmosis.

    UV reverse osmosis water filtration is a commonly utilized water purification technology across the globe. This technology integrates ultraviolet water disinfection and reverses osmosis to elevate water purity levels. A reverse osmosis system is first utilized to capture dissolved solids, minerals, certain microorganisms, and organic compounds. The microbial pathogens left in the RO permeate are effectively inactivated by the integrated UV disinfection unit.

    ● Ion exchange.

    Ion exchange simply extracts dissolved ions from water and replaces them with non-objectionable ions. When pretreating feed water, this process gets rid of iron, magnesium, nitrates, chloride, and calcium among others. These are impurities capable of absorbing the germicidal rays thereby lowering UV dose and the sterilization rate.

    ● Ultrafiltration.

    In the modern age, the use of ultrafiltration in pretreatment has grown exponentially. It is a membrane purification technique that traps suspended matter and slight amounts of dissolved solids using partially permeable membranes. With a membrane porosity measuring approximately 0.005 to 0.1 μm, UF filters extract virtually all suspended solids and greatly decrease turbidity.
