The Need for Water Purification
Growing concern over waterborne diseases has driven the demand for new efficient water treatment systems. Drinking water could be contaminated with microbial pathogens such as protozoa (Cryptosporidium, Giardia), bacteria (E. coli, Salmonella), and viruses (Hepatitis A & B, Rotavirus). As a result, disinfection of water has become a crucial part of the water treatment process.
UV Water Treatment
Ultraviolet (UV) irradiation has emerged as one of the best water disinfection alternatives in the last few years. Currently, many major cities in Canada, United States, and Europe are adopting UV as their primary water disinfection process, making UV one of the fastest growing water treatment technologies.
UV water treatment provides a proven and safe alternative for water treatment that is free of harmful chemical byproducts. UV radiation essentially eliminates microorganisms through disruption of their generic core. When bacteria, viruses and protozoa are exposed to the germicidal wavelengths of UV energy, their DNA or RNA is severely damaged. As a result, they are rendered incapable of reproducing and infecting.
UV-LEDs vs. UV-Lamps
The conventional technique for UV water treatment utilizes UV mercury lamps. Unfortunately, there are several concerns related to the environmental impacts and performance limitations of UV-lamps. These include, their high operating power and voltage, short lifetime and the inability to frequently turn them on/off. Further, the cylindrical shape of the UV-lamps limits the reactor’s design and efficiency.
Acuva’s breakthrough water purification systems utilize UV-LEDs for UV water treatment. Recent advances in light emitting diodes (LED) technology allow LEDs to generate UV radiation at the wavelengths for microorganism inactivation. The use of UV-LEDs provides Acuva systems with a number of advantages over the conventional UV-Lamp systems.
|Power consumption||✔ Low||High|
|Start time||✔ Instant||Long|
|Environmental impact||✔ Friendly||Mercury used|
|Life cycle||✔ >10 years||1 year|
|Hazards (eye, skin)||✔ Safe||Dangerous|
|UV source replacement||✔ None||Annual|
Due to these advantages UV-LED systems are replacing traditional UV mercury lamps and transforming water treatment systems.
Acuva’s Water Treatment System
A dual barrier solution in a compact design that can be easily installed.
Acuva’s UV-LED reactors, expose microbial pathogens to the UV dose recommended by the NSF Standard. Our proprietary design allows for the UV rays to be concentrated directionally, maximizing deactivation effectiveness while minimizing power usage.
Before entering the reactor water is filtered through an integrated filter to remove particles and enhance the taste, odour and colour of water.
How it Works
UV-LED Reactor: Effectively inactivates harmful microbial pathogens
Composite Filter: Remove particles and odour causing chemicals, enhancing water taste
Source Water: Water at risk of microbial contamination
