The post appeared first on . Source: Water Feed UV irradiation at 254 nm effectively inactivates antibiotic-resistant bacteria (ARB) and reduces antibiotic resistance genes (ARGs) in water. For greater ARG reduction, combining UV with advanced oxidation processes like UV/H2O2 is more effective, forming a key component in next-generation water treatment strategies. Microbial inactivation alone is insufficient because pathogenic genes, specifically antibiotic resistance genes (ARGs), can persist in treated water even after disinfection. These ARGs enable microorganisms to develop resistance to antibiotics, necessitating a broader approach to water purification beyond just pathogen removal. Conventional UV lamps are the established technology for inactivating microorganisms and destroying ARGs in water. UV-LEDs are emerging as a novel alternative, currently undergoing lab-scale investigation, and offer several attractive advantages for future antibiotic resistance control applications in water and wastewater treatment. Research demonstrates that combining UV irradiation with advanced oxidation processes (AOPs), such as UV/H2O2, significantly improves the reduction of antibiotic resistance genes (ARGs) compared to UV alone. This synergistic approach provides a more comprehensive strategy for controlling antibiotic resistance in water purification systems.

Quick Answer: UV light at 254 nm really works to kill antibiotic-resistant bacteria (ARB) in water treatment. It also helps cut down on antibiotic resistance genes (ARGs), though it won’t get rid of them completely. Studies show that when you combine UV with advanced oxidation processes (UV/H2O2), you get an even bigger drop in ARGs than with UV alone. This makes it a super promising part of future water treatment plans for fighting antibiotic resistance.
water. But we need to think about disinfection differently now. Just killing microbes isn’t enough to guarantee safe water, because nasty genes can stick around even after treatment. Antibiotic resistance genes (ARGs) are a huge worry; they’re what make microbes resistant to antibiotics in the first place. UV light has been widely used for disinfection and, more recently, for destroying ARGs. While traditional UV lamps are still the main way to do this, UV light emitting diodes (UV-LEDs) are new UV sources. We’re seeing more and more lab studies that show them as a real alternative. This review talks about how we’re currently using UV technology to control antibiotic resistance in water and wastewater treatment. UV-LEDs offer some great benefits over older UV lamps. So, we’re taking a close look at how UV-LED features, like single versus combined wavelengths, and how they operate, such as periodic, pulsed, or continuous light, pulse repetition frequencies, and duty cycle, affect things. We’re also checking out the type of organism and how it responds to the UV dose. Our goal is to pinpoint what research we still need to do to tackle future disinfection challenges. We’re also checking the energy efficiency of these UV processes, focusing on how well they actually disinfect. We’ve learned a lot from using UV lamps, and that experience can help us explore UV-LEDs for similar jobs, like fighting antibiotic resistance. This will help us figure out where to go next with our research. (C) 2019 Elsevier B.V. All rights reserved.
