Rapid online analysis of phosphorus content

The Liquiline CA80TP phosphorus analyzer (photo) is designed for monitoring industrial wastewater and inlet and outlet streams of municipal wastewater treatment plants. The CA80TP uses a thermal digestion technique along with colorimetric analysis, requiring only a small quantity of reagents. With online measurement, there is no waiting for time-consuming laboratory analysis. The CA80TP measures phosphorus in ranges of 0.05 to 10 mg/L or 0.5 to 50 mg/L. It has two 4–20-mA outputs with the option for additional outputs. Samples are drawn from the process using a suction strainer or can be taken from a bypass piping system. A precise sample volume is digested at high temperature with a digestion reagent. An optical dosing unit — to dose sample and reagents — uses a redundant light barrier for a high level of reliability, guaranteeing precise and reproducible results from extremely small volumes of reagent. The CA80TP has a software-controlled safety cover to prevent access to the digestion reactor when it is under operation. — Endress + Hauser Inc., Greenwood, Ind.
