    The Ultimate FAQ Guide for UV Water Purifiers.

    According to the WHO, approximately two billion people across the globe depend on a water reservoir degraded by fecal contamination. This exposes the people to devastating waterborne illnesses such as diarrhea, which is approximated to cause 485,000 deaths annually. These illnesses and regrettable deaths can be prevented by utilizing essential water purification technologies such as ultraviolet sterilization. This technology kills virtually all microbial pathogens responsible for transmitting waterborne diseases. In today’s article, we will be shedding more light on UV water purifiers and their role in combating waterborne illnesses.

    Figure 1 Household UV water purifier.

    What is a UV Water Purifier?

    A UV water purifier is simply a water treatment device designed to purify water with microbial pollutants using germicidal radiation. Typical UV  purifiers are simple systems made up of four primary components, the UV chamber, the UV lamp, the quartz sleeve, and the ballast. This makes them easy to install, use and maintain. Ultraviolet water sterilizers are dependent on germicidal rays. As such they do not rely on chemical reagents, thus they are comparatively safer and more environmentally friendly than chlorination.

    Primarily, UV  purifiers are employed to supplement other water purification systems, specifically in the polishing phase. In the modern world, their application fields have diversified massively transcending from home water treatment to industrial water purification. The inactivation of different microbial pollutants necessitates varying levels of light intensity hence most typical UV water purifiers are manufactured with light intensities ranging from 30,000 to 50,000 µWatt•sec/cm².

    What is the Role of UV Water Purifiers?

    Ultraviolet water purification units are principally designed to kill bacteria, viruses, and other objectionable pathogens. They are mainly deployed as post-treatment systems for other water purification systems but they can also be used as standalone water purification units depending on the feed water’s characterization. In homes, they are principally used to purify drinking water. As such, they are either installed at points of entry to treat all incoming water or at points of use to exclusively purify drinking water.

    UV water purifiers are also highly coveted in commercial fields such as water bottling, restaurants, and car washing. In-car washing, they are chiefly used to purify water used in the final rinse to achieve spot-free surfaces. Their use in water bottling is mainly in the post-treatment stage whereby they refine the filtered water generated by other systems e.g. water deionizers and reverse osmosis systems.

    In addition, they are exploited differently by dissimilar industries. In pharmaceutical industries, they are used to purify product water, cleaning water, and water for injections among others. UV purifiers are also crucial in industrial effluent treatment where they are deployed to shrink the microbial count in the final treatment stage. In the latter years, municipalities supplying households with potable water have also embraced UV water purification plants.

    How Do UV Water Purifiers Function?

    Ultraviolet water sterilization is a water purification technique that kills microbial contaminants in water using germicidal UV-C light. Prior to UV sterilization, the feed water is first pretreated to eliminate inorganic compounds and suspended matter. Typically, 5 to 20-micron filters are deployed to seize aggressive solids likely to block the transmission of the germicidal rays. Ion exchange systems or iron removal filters are deployed to lessen the iron content while RO systems are called upon to extract Total Dissolved Solids (TDS).

    The preconditioned feed water is then driven into the UV water purifier. Here, the water enters into a reactor chamber holding the UV lamp, which is enclosed in a quartz sleeve. The UV lamp discharges germicidal UV-C light which transmits through the glass quartz sleeve to reach the waterborne microbes. The germicidal rays distort the nucleic acid of the pathogens ultimately halting their growth and reproduction.

    Different microbes have varying characterizations and necessitate varying levels of UV dose and contact time for them to be effectively deactivated. For instance, to kill 99.99% of E. coli and coliform bacteria, the ideal UV dose is 6.6 millijoules (mJ). Rotavirus and adenovirus on the other hand are effectively inactivated at 24 mJ and 40 mJ respectively. The following quick video depicts how a standard UV water purifier operates.

    Which Sources of Water Necessitate UV Water Purifiers?

    Virtually all sources of water are susceptible to microbial pollution. Viruses and bacteria might find their way into the water through natural means or manmade activities like wastewater disposal. Thereby, purifying feedwater drawn from contaminated sources like rivers, seas, oceans, wells, and even tap water will most likely necessitate UV sterilization. The water drawn from these distinct reservoirs typically has dissimilar impurity compositions and concentrations.

    Therein, different water purification systems are needed to extract the dissimilar pollutants. UV water purifiers are primarily employed in conjunction with other water treatment equipment. Conventional water treatment systems deployed to treat seawater, tap water, brackish water, wastewater or well water are incapable of killing all microbial pollutants. For this reason, they are often supplemented by UV water sterilization post-filters.

    As long as there is an appropriate water purification system customized to purify water from the specified source, a UV water purifier can be deployed thereafter. Testing the feed water to gain a glimpse of the microbial impurities present is essential. This will help in understanding the befitting UV lamp intensity, the appropriate UV dose, and ideal exposure time.

    How Effective Are UV Purifiers?

    Of all water purification systems tasked with extracting microbial pollution, UV water treatment systems are without a doubt, the most effective. They have a microbial inactivation score of 99.99% when utilized appropriately.  However, the effectiveness of UV water purification systems is often influenced by the feed water concentration, exposure time, and UV dosage.

    The feedwater must be subjected to sufficient pretreatment to extract constituents likely to absorb or shield the reach of the UV-C radiation. A lamp intensity of 30,000 to 50,000 µWatt•sec/cm² is also needed to kill all living microorganisms. Protozoan parasites and vegetative bacteria are extensively inactivated at considerably lower UV doses ranging from 1 to 10 mJ/cm2.

    Bacteria spores and enteric viruses, on the other hand, necessitate high UV doses (30 to 150 mJ/cm2) to be extensively inactivated. The wavelength needed to completely inactivate all microbes is approximately 253.5 nm. To uphold the optimal functioning of the UV water filter, it is imperative that you take quality care of the UV lamp and the quartz sleeve. The quartz sleeve will need periodic sterilization to flush out films of impurities that build up during the in-service cycle. Exhausted lamps with insufficient light intensities should also be replaced early to mitigate lower sterilization rates.

    What Specifications Must UV Water Purifiers’ Feed Water Meet?

    To augment optimal disinfection and mitigate system fouling, the feed water injected into an ultraviolet disinfection unit must meet certain conditions. This is primarily why most UV water purifiers are installed next to other water treatment systems. For instance, 5-10 micron filters are frequently exploited to ensure the feed water has a maximum total suspended solids (TSS) level of 10 mg/L. The pretreatment filters also decrease the turbidity levels to 5 NTU or lower.

    The removal of suspended solids and turbidity makes the feed water clear and allows optimal exposure to the germicidal rays. Feedwater with high concentrations of suspended solids is difficult to optimally sterilize given that floating solids can shield the microbes from the UV-C germicidal rays. The iron content should not exceed 0.3 mg/L hence you might need a water deionizer system or an iron removal filter.

    The maximum manganese level should be less than 0.05 mg/L and the water hardness should be 7 grains per gallon or lower. Water hardness is essentially caused by calcium and magnesium minerals. These minerals are effectively extracted using water softener systems. To mitigate the premature fouling of your UV water purification system, ensure that your feedwater adheres to the guidelines stipulated in the table below.

    Parameter. Maximum level.
    Suspended solids (TSS) <10 Mg/L
    Hardness <7 GPG
    Iron <0.3 ppm
    Turbidity 5 NTU
    Tannins <0.1 ppm
    Manganese 0.05 ppm.
    UV transmittance >75%
