LED technology makes UV water treatment more efficient

Ultraviolet disinfection is a well-established method for achieving adequate disinfection of drinking water. The process is intended to inactivate human pathogens such as viruses, bacteria and protozoa that are potentially present in raw water before receiving proper disinfection. As water passes through the UV unit, an ultraviolet range of light inactivates these human pathogens.

Conventional UV disinfection systems for water treatment use UV mercury lamps. However, Acuva Technologies has now applied the technology to the energy efficiency of LED lighting in its UV-LED water disinfection system. The system, according to Manoj Singh, president and CEO of Acuva, uses the proven technology of ultraviolet germicidal irradiation and LED lights to disinfect drinking water that is produced in an energy-efficient and environmentally friendly manner.

“We believe that access to safe drinking water is everyone’s fundamental right,” he says. “But even today, around 25% of the global population does not have access to safe drinking water. This is primarily because current technological options either do not produce adequate purity or they do not work with the current infrastructure available.”

UV disinfection uses strong short-wavelength radiation to inactivate microorganisms by destroying the nucleic acids and disrupting their DNA. The Acuva system purifies water in two steps. A composite filter removes sediment while activated carbon removes impurities. The UV-LED chamber then sterilizes harmful bacteria and viruses.

“Unlike chemical treatment techniques, UV is free of harmful byproducts,” says Ashkan Babaie, director of Advanced Engineering for Acuva. “It doesn’t change the taste, odor or color of the water.”

In addition, according to Acuva, UV-LED technology is more compact, uses less power, starts instantaneously and offers a longer life span than mercury lamps. These capabilities allow it to be used in a more flexible nature in not only homes and businesses, but also watercraft, recreational vehicles and remote vacation homes and cabins with suspect drinking water quality.

Acuva’s IntenseBeam technology allows for precise control of optics, hydrodynamics and kinetics within the UV chamber to deliver an intense beam of ultraviolet light directly into flowing water, creating additional efficiencies. The optic and hydrodynamic design creates a controlled environment matching water velocity and UV irradiance to ensure full disinfection throughout the chamber. These complete low-power, flow-activated systems save on power consumption while extending LED life. 800-980-8810;
