    Application Process

    Drinking Water Disinfection

    Using ultraviolet (UV) light for drinking water disinfection dates back to 1910. It is a reliable means of disinfection which involves exposing contaminated water to radiation from UV light. The treatment works because UV light penetrates an organisms cell walls and disrupts the cells genetic material, making reproduction impossible.

    A special lamp generates the radiation that creates UV light by striking an electric arc through low-pressure mercury vapor. This lamp emits a broad spectrum of radiation with intense peaks at UV wavelengths of 253.7 nanometers (nm) which research has shown is the optimum UV wavelength range to destroy bacteria.

    UV disinfection can remove the threat to health from water borne Pathogens without the creation of disinfection by products that can be generated from drinking water chlorination. From the common bacteria, E-Coli through the Cryptosporidium Oocysts to Adenovirus, UV disinfection is capable of providing effective treatment to ensure inactivation of these pathogens and ensure drinking water is safe.

    UV is simple to install and requires little supervision, maintenance, or space. Improved safety, minimum service time, low operation and maintenance costs, and the absence of a chemical smell or taste in finished water are some of the major advantages for selecting UV technology over traditional disinfection technologies.

    Process Water Disinfection

    Ultraviolet light is proven to be a cost effective method for reducing microbial contamination in water. As such, UV is becoming increasingly common for disinfection, across a wide range of applications and industries:

    Contaminated Rinse water for consumable products can shorten product shelf life and creates the potential for human infection. For manufacturing processes rinse water must be clean to ensure product quality and protect equipment from aggressive impurities.

    As water costs increase, Water recycling loops that utilize UV for disinfection are a cost effective way to use water for multiple operations prior to discharge. Microbial growth in Cooling water and the associated bio-film can shorten the life of equipment and cause costly down-time or chronic manufacturing issues.

    Discharge water is becoming the focus of increased scrutiny from pollution control boards. For many companies it is necessary to disinfect discharge water and UV is often the best option because it is reliable and does not create residual byproducts.

    The Alfaa UV Hiflo and APi Series are the perfect products to help you with your rinse water. The WWR series is the solution for water recycling and reuse. Our compact design offers the most energy efficient solution for process water disinfection. Contact us today for more information.

    Wastewater Disinfection

    Wastewater quality measurement parameters commonly used in India focus on BOD, COD, TSS etc. Microscopic bacteria & viruses which can neither be seen nor smelled are present in abundant quantities in tertiary treated wastewater posing a grave but silent threat. All commonly heard of water borne diseases such as Typhoid, Hepatitis and Gastroenteritis originate from wastewater.

    Most developed countries that reuse wastewater, have stringent guidelines on the microbiological contamination levels present in the wastewater before it is allowed to be reused. These norms pay particular emphasis on treatment required in an urban setting. Because urban reuse usually involves irrigation of landscapes (with unrestricted public access) or other types of reuse where human exposure to the reclaimed water is likely (such as toilet flushing, car washing etc.) Reclaimed water must be of a higher quality than may be necessary for other reuse applications. Therefore, while recycled wastewater might appear clean and clear to look at, high levels of dangerous pathogens require that wastewater be thoroughly disinfected prior to reuse.

    Swimming Pool Disinfection

    Most pools and spas depend on chemicals to sanitize them. Traditionally, chlorine has been in use for more than 40 years to create safe pools. However, it is increasingly being known that during typical chemical disinfection, chlorine and other chemicals react with organic matter to form hundreds of new chemicals- disinfection byproducts such as chloramines, that have been linked to redness and burning of eyes, skin irritation, asthma, allergies and even cancer. New studies show that your swimming pool may turn out to be dangerous water. Some have even compared the risks of pool chemicals to those of second hand smoke.

    Chlorine and Chloramines are known to cause burning of eyes, skin irritation, and even asthma.

    Ultraviolet or UV is being recognized as a safer, more cost effective and environmentally friendly alternative to traditional chlorination and has become the preferred choice for swimming pool treatment worldwide. Internationally, the pool industry is moving to UV. With regard to pool sanitation, the World Health Organization (WHO) states that Lower free chlorine concentrations may be health protective when UV is used.

    Toc Reduction

    Reduction of Total Oxidizable Carbons (TOCs) in water is achieved via three types of reactions initiated by UV that work to destroy and/or remove oxidizable carbons.

    The primary UV/chemical reaction is an oxidation process that begins when high-energy 185 nm UV dissociates water molecules, thereby creating hydroxyls (free OH- radicals). The hydroxyls created by UV are highly reactive and readily combine with other molecules, such as the hydrocarbon molecules that make-up TOCs. When hydroxyls combine with the TOC hydrocarbons they form water and carbon dioxide molecules; TOCs are destroyed and the oxidation is complete.

    The second type of UV reaction that works to remove TOCs is one whereby the ultraviolet photons dissociate organic molecules directly. This result is TOC removal/ TOC reduction by means of destruction. A third UV reaction occurs when deionization is added downstream of a UV reactor. Ultraviolet energy will ionize TOCs, which allows for subsequent removal by a deionization system.

    One of the challenges of using ultraviolet energy for TOC reduction is that 185 nm UV does not transmit as well through water as does 254 nm UV. Therefore, a very high UV dose is required for TOC reduction as compared to standard disinfection. As a thumb rule, a minimum UV dose of 1500 J/m2 is required for TOC reduction.

    A side benefit of using UV for TOC reduction is that the TOC lamps will generate significant levels of 254 nm output and consequently provide high levels of microbial reduction (disinfection), in addition to the TOC reduction.

    Ozone Destruction

    Ozone can come from a variety of sources, and often serves as an important component to a comprehensive water purification system. However, residual ozone represents a potential health hazard and it can be damaging to finished goods, as well as to processing and fabrication equipment. Using UV to remove ozone has an advantage because UV does not require additives that may leave behind residuals. In addition, dissociation of ozone with UV may also help to oxidize some TOCs.

    Germicidal ultraviolet light destroys Ozone in water very quickly. Therefore, the 254 nm wavelength produced by low- pressure germicidal UV lamps is quite effective for ozone destruction from water. The mechanism for removing ozone is dissociation, which occurs when 254 nm UV energy breaks one of the oxygen bonds in an ozone molecule. As a result of this reaction, each ozone molecule is converted into one oxygen atom and one oxygen molecule. Free oxygen atoms will combine with each other to form oxygen molecules.

    254nm germicidal lamps are used for ozone destruction because they utilize a quartz envelope that blocks the 185 nm wavelength generated by low-pressure lamps.

    Although ozone is readily destroyed by UV, it requires more UV energy than inactivation of microorganisms. As a thumbrule, a minimum UV Dose of 900 J/m is requred against a dose of 300 J/m needed for disinfection. Therefore, in order to ensure effective ozone destruction, UV systems are often sized using a flow-rate adjustment of 30%  40% the flow-rate of a disinfection system. However, for certain larger flow rates, customized UV reactor with special internal baffles are utilized.

    UV Based Air Disinfection

    UVGI is a proven method for removing volatile organic compounds(VOCs) and for killing or deactivating bacteria, viruses, mould spores and other pathogenic microorganisms that may be present in room air.

    Application Areas Hospitals UltraCoil & UltraDuct systems destroy high levels of airborne and surface bio contaminants. Infections Aquired in Hospitals (HAI) can be a significant cost for the healthcare industry and is considered a preventable injury. Ultra IAQ systems are the ideal tool to help reduce nosocominal infections

    Pharmaceutical, Food Processing And Produce

    Air quality and the risk of surface contamination play a vital role in pharma clean rooms, and in the production & packaging of food products. UV Sterilization of both air and/or surface of product or packaging by UltraHVAC UV systems can dramatically reduce possibility of contamination. In fruit/vegetable markets it can extend the life of the produce by destroying the off gassing (i.e ethylene) which cause faster aging.

    Commercial Spaces, IT Parks And Schools

    A WHO report suggested up to 30% of new and remodeled buildings worldwide may be subject to complaints related to poor indoor air quality, the leading cause of Sick Building Syndrome.` According to the EPA, poor indoor air quality can directly affect the health of students, staff, employees, which in turn affect attendance and performance. Using UltraHVAC UV systems significantly improves air quality resulting in lower absenteeism and higher efficiency.
