Assimilable Organic Carbon (AOC)

Assimilable Organic Carbon (AOC) is an important cause of microorganism re-growth in drinking water distribution systems. A high AOC concentration allows re-growth of bacteria that has survived drinking water disinfection. AOC consists of a broad range of low-molecular-weight organic carbon molecules, such as sugars, organic acids, and amino acids that are more easily assimilated by microorganisms than other types of organic carbon. It is considered one of the main indicators of biological water stability.

    Titanium Spectrometer - Overview

    This titanium spectrometer probe is a multi-parameter instrument that can measure multiple water quality parameters continuously. Its rugged design is suitable for use in high-pressure and high-temperature environments. As the probe comes into direct contact with the water, there is no need for complex sample pre-treatment. It is installed and operated by the easy "plug and measure" principle. The titanium spectrometer probes can be installed quickly and effortlessly, either submersed (InSitu) or in a flow-through setup (Bypass, monitoring station). It also comes with an automatic cleaning system that uses compressed air to clean the sensors. This system has proven highly efficient and reliable, even in untreated wastewater. The s::can spectrometer probes are intelligent instruments that use software-controlled procedures to identify any fouling on the measuring.

    The titanium spectrometer monitors the following parameters depending on the applications selected: TSS, turbidity, NO3-N, COD,  DOC, UV254, NO2-N, BOD, TOC, color, O3, HS-, BTX, AOC, fingerprints, and spectral alarms, temperature, and pressure.
