Trends in optical monitoring.
Optical techniques are often used for the development of new monitoring systems for wastewater quality. The different techniques, light scattering, UV-IR spectrophotometry, fluorimetry and image analysis have given rise to recent instruments but are often limited for industrial applications. After the presentation of the principles, the advantages and drawbacks are discussed with respect to given applications.
