How to apply and maintain photometric/colorimetric analyzers

Key considerations for monitoring ammonium and orthophosphate in wastewater

Water resource recovery (WRR) plants must monitor ammonium and orthophosphate. Permitted levels for these nutrients in effluent discharge are becoming increasingly tight because state environmental agencies and the U.S. Environmental Protection Agency (EPA) are requiring dischargers to reduce the amount of nutrients in their effluent. Photometric/colorimetric analyzers can be used to monitor ammonium and orthophosphate.

Attaining value

Photometric/colorimetric analyzers provide valuable information for the efficient operation of a WRR plant. With careful consideration of several key attributes, plant operators can reliably obtain years of high-quality data at a reasonable cost.
