Market Profile: Spectroscopic Process Water Analysis

Spectroscopic analytical techniques accounted for more than 10% of the process water analysis market in 2006. The two technologies that essentially make up this market segment are turbidimeters and UV photometers. Use of direct online spectroscopic methods is limited to a few relatively large application areas.

Turbidimeters measure the haziness or cloudiness created by suspended solids in water. Modern turbidimeters consist primarily of nepholometers, which measure the reflected light at 90° from a visible light source. Process UV instruments that are used for water analysis consist primarily of single or dual wavelength photometric probes that can detect organic compounds. Discrete analyzers, which must perform some type of reaction prior to detection and can be designed to detect a range of species, are not included.

Online turbidity measurement is used heavily in both industrial effluent monitoring as well as water treatment facilities. Dirty water that is pumped into municipal water systems from industrial facilities often is required to meet specific turbidity requirements, especially in the U.S. Municipal water treatment plants also monitor incoming water for treatment, as well as outgoing water that already has been treated, to verify its quality. Direct UV photometric probes are used for analyzing nitrogen compounds, such as nitrates and nitrites, and are found primarily in water treatment facilities.

The combined market for online direct spectroscopic water analysis methods was worth about $50 million in 2006 and is expected to see annual growth in the mid-single digits. The foregoing data were extracted from SDi's market analysis and perspectives report entitled The Water Testing & Analysis Market: Lab & Process — Wastewater to Ultrapure Water.
