Phosphate Analyzer and Control System

The measurement of Phosphates and total Phosphates is useful in a variety of  industrial and municipal wastewater treatment applications.  Phosphates and total phosphates are commonly measured before the release of treated wastewater effluent from power and chemical plants where they occur in boiler feed water and cooling water systems.  In addition, they are measured in municipal drinking water and sewage treatment plants.

While phosphorus is naturally present in the environment and used in the fertilization of agricultural crops, it is a danger to the sensitive aquatic plants found in surface waters such as streams, rivers, ponds, lakes, etc.  Phosphate pollution is a serious concern, and it is monitored by governmental authorities around the globe to protect plant life, animals and humans from the effects of over-exposure.

The CA-6 Colorimetric Phosphate Analyzer helps wastewater treatment engineers to measure these parameters accurately and reliably, via on-line sequential sampling. It automatically samples, analyzes and then processes results. The colorimetric method of water analysis relies on an LED light source and a heated colorimetric cell designed for measuring trace amounts of an analyte in the water, which is equivalent to the phosphate levels present.
