UV transmittance and absorbance testing carried out at CLS to support water quality assessment and UV treatment performance.
UVT, or Ultraviolet Transmittance, measures the percentage of ultraviolet light that passes through a water sample, typically at a wavelength of 254 nm. This testing is widely used to assess water clarity and determine how effectively UV light can penetrate the sample during ultraviolet disinfection processes.
Water with higher UV transmittance allows UV light to pass through more easily, supporting effective UV disinfection. Lower UVT values indicate that substances within the water are absorbing or blocking UV radiation, which may reduce the efficiency of UV treatment systems.
UVA, or Ultraviolet Absorbance, measures the amount of ultraviolet light absorbed by compounds present in a water sample. This analysis provides information about the presence of dissolved organic substances that can affect water quality and treatment processes.
Higher UVA values generally indicate increased levels of organic material that absorb UV radiation. UVA testing helps treatment facilities understand the composition of water and evaluate how organic compounds may influence treatment performance, particularly UV disinfection systems.
CLS provides UVT testing and UVA testing services to support environmental water analysis and treatment process monitoring. Testing is carried out in the CLS laboratory using calibrated analytical equipment to ensure accurate and reliable measurement of ultraviolet transmittance and absorbance.
By providing dependable UVT testing and UVA testing, CLS supports water treatment facilities, environmental monitoring programmes, and industrial clients in assessing water quality and optimising treatment performance. The data generated helps clients better understand the characteristics of their water and maintain effective UV disinfection processes.
