Abstract:
The specific wavelength of 525 nm is described as a single monochromatic light source used in the determination of turbidity by nephelometry at 90° for particulate matter in raw water, water treatment, waste water treatment and industrial process streams. This wavelength improves the detection of smaller particle concentration in water where light scattering characteristics of shorter wavelengths are superior to light sources using longer wavelengths.
