In the realm of environmental and water treatment, the seemingly simple acronym SUVA stands for Specific Ultraviolet Absorbance. This powerful tool, often overlooked in the broader conversation, plays a critical role in assessing the quality and potential risks associated with water sources.
What is SUVA?
SUVA measures a water sample's absorbance of ultraviolet (UV) light at a specific wavelength (typically 254 nm) relative to its concentration. Essentially, it quantifies the amount of UV light a water sample absorbs, giving us a valuable insight into the presence and nature of organic matter within it.
Why is SUVA Important?
