Wastewater

Real-time monitoring of wastewater treatment

Unlike traditional analysis techniques, the Spectro Inlets solution provides real-time insight into the chemical contents of the water at different steps throughout the cleaning process. There is no need to wait for GCMS or LCMS results. Changes in chemical contents can be detected under a minute and can be acted upon enabling the optimization of the cleaning process and monitoring pollutants.

The same system can also be used to monitor effluent gases. No additional training is required to gain insight into the measured compounds.

Wide range of detectable compounds – simple addition of new compounds of interest

Any kind of dissolved gas and compounds with vapor pressure can be detected and monitored. These include among others H2, CH4, NH3, N2, O2, H2S, N2O, NO2, EthOH, toluene and light VFA’s (e.g. formic acid). Quantitative analysis from ppm levels to 100% analyte concentration. Once the system is set up, detection of additional compounds can be done without change of hardware in minutes.

Self-cleaning detector withstands the harsh environment of wastewater treatment tanks

The wetted components are surface treated and made of chemically resistant materials such as stainless steel 316 and SiO2, meaning that they can withstand harsh chemical environments. Robustness tests in fermentation tanks (>3 weeks immersion) showed no indication of biofilm growth so far. Furthermore, the inlet system is self-cleaning, meaning that in case of any dry material being stuck to the surface can be removed by bubbling gas through the inlet system without stopping the reactor or the flow in the pipe it is attached to.

Data is immediately available and can be integrated into SRO systems

Data from the system can be reached and used through multiple channels: data can be uploaded to a secure database for cloud storage, with access through a standard web browser or an API. The system can also provide data through MODBUS protocol for easy integration into existing industrial control (ICS) systems and easy communication with PLCs. Furthermore, custom communication protocols can be integrated on request to facilitate easy integration.

Easy integration and low maintenance

The system is designed to be attached to standard DIN flanges directly on pipes or tanks (DIN 80 or larger). Working pressures up to 4 bars and temperatures up to 80°C (higher application temperature is possible on request) are possible making the system compatible with a variety of processes. The same system can be used for both liquid phase measurements and also for analyzing effluent gases. Routine maintenance is expected once in every 2 years and can be made in the field creating high uptime and continuous data stream.
