Now Mercury Free Drinking Water With UV LED Technology

Due to the potential health issues caused by different types of contaminations present (and potentially added) in drinking water, water filters and filtration methods must be used and consistently updated as per the available technology.

As a society, we collectively make some mistakes and, unfortunately, keep repeating them. The Indian population is constantly conscious about household and physical cleanliness. Our customs and rituals are based on cleansing one’s home and physical surroundings. However, whilst doing so, we often presume that what looks clean is uncontaminated. This is true in the case of drinking water with all the purification systems and filtration devices installed. We make the wrong assumption of ignoring microorganisms, bacteria, and even viruses present in a crystal-clear glass of water. Furthermore, there is a wide range of waterborne diseases, and ignoring this factor could result in serious health repercussions.

The primary purpose of installing a water purification system in a house or office is to ensure that drinking water is safe and fit to drink. Any purification system costs a good amount in purchasing and further maintenance. However, there are several limitations (or disadvantages) of the existing purification systems. There can be contaminations caused by the pipeline, container, and even storage source.

The limitations of traditional water purification systems

1. Chemical Disinfection Systems (Chlorine and Ozone)

Traditionally, governments, local authorities, and household levels have introduced some water purification systems. Starting with chemical disinfection using substances such as chlorine and ozone-based treatment methods. These are largely popular and effective. However, such treatments are inadequate (for removing all harmful infectants) and could prove extremely dangerous for consumers’ health. There is a challenge for storage and usage of such chemicals, and hence it could cause more harm than benefit if used inappropriately. This is the case with chlorine and ozone-based treatment methods and a few other chemicals such as iodine crystal and silver ion.

2. Filtration (RO and advanced-ceramic filters)

Filtration is another traditional tool that has proved to be highly effective but has several limitations. The maintenance costs of the system are too high. Furthermore, filtration fails to remove microorganisms such as viruses. Bacteria are often trapped and not killed, due to which there is a chance of secondary contamination easily.

3. UV-lamp Technology

Usage of UV-lamps-based disinfection is also widespread and has helped address the fundamental issues that were open in the case of filtration. However, due to the presence of mercury in the UV lamps, it is an inherently dangerous way of water treatment. The operating costs and voltage requirements of such systems are also relatively high. Furthermore, UV lamps can limit the design and efficiency of the purification systems.

The best technology available: UV-LED at Point-of-Use

One of the solutions to the limitations and disadvantages of the traditional treatment methods could be introducing UV-LED technology for water disinfection at point-of-use. Usage of UV-LED technology is revolutionary in many ways. It operates at low energy and can generate UV energy at sharp emission spectra and tailored peak wavelength that targets maximum absorption into microorganism DNA. In simple words, the operating costs are low, and it effectively covers all kinds of microorganisms and viruses, which are often exempted by filtration methods.

On a fundamental basis, UV-LED technology takes account of all the limitations and issues which are not covered by the traditional filtration methods. There are no bacteria, viruses, microorganisms, or spores that can withstand this treatment. There are many additional advantages that UV-LED technology has over its predecessors, based on which it should be the first choice as a water treatment method.

The devices based on this technology can operate instantly on/off, and hence a lot of energy is saved. Unlike UV-lamp based filters, this technology does not take account of any harmful or hazardous elements such as mercury. In case of UV-LED there is no warm-up time required to initiate operations, and these machines cause no environmental hazards.

Acuva Technologies is one of the first companies to introduce UV-LED technology in the water filtration and treatment process. It is a Gold Standard purification method that provides a prolonged and high level of disinfection without any performance issues or degradation. Acuva has ensured that the technology could be easily integrated into any home or office water purifier. The company aims to resolve the point-of-use drinking water requirement regarding safe drinking water suitability to the next level. Acuva has more than 23 patents on technology that aims at addressing all the issues that are required to provide UV-LED based disinfection systems for the benefit of the public at large.

Summing up

To sum up, due to the potential health issues caused by different types of contaminations present (and potentially added) in drinking water, water filters and filtration methods must be used and consistently updated as per the available technology. The traditional filtration techniques have worked well but had some limitations due to which the fundamental objective of just filtering water was not enough. UV-LED technology is now available to consumers to take advantage of water filters whilst not encountering any hazardous elements such as mercury to address all the given challenges. So, whilst deciding for choosing a water purifier for home or office, it is crucial to check on UV-LED based water purifiers.
