Water Quality Montoring System/Analyzer For STP

Water plays a important role in the life of human beings and other natural things. Most diseases are caused because of contaminated and polluted water. As we all know water is not only used for drinking purposes .It has other uses too like in industrial sites for agriculture purpose, for fishing and construction activities etc. The quality of water is mainly affected by physical, chemical and biological aspects.

Drexel water quality Monitoring System/Analyzer are widely used to monitor industrial effluent, effluent generated by STPs, rivers and other types of water bodies. Drexel Water Quality Monitoring Systems are certified by various international certifying agencies including TUV, CE, ISO ,EN.

Drexel Water Quality Monitoring System/Analyzer are based on the probe sensors/Extractive assembly which are used to measure the ETP/STP Drinking Water with standard parameters like BOD,COD ,TSS,PH, TDS and additional parameters like DO (Dissolved Oxygen) ,NH₄NO₃,TDS, Turbidity, Residual Chlorine, Hardness, Salinity, Orthophosphate, Total Phosphate, Temperature and conductivity.


Drexel DX4B is a multi-parameter system, and it works on an extractive measurement technique wherein the emission levels are measured by extracting the heated gas from the stack, and before feeding to the analyzer it is cooled to the required sampling temperature. The Stack gas parameters are measured with NDIR and FTIR/DOAS analyzer assembly. SPM is measured with DC-Triboelectric and Laser Back Scattering Method.


Drexel Water Quality Monitoring System/Analyzer equipped with probe type sensors can be placed directly in the tank or sensors can be enclosed in assembly box. Since the assembly box has automatic cleaning cycle with extract water arrangement. The extractive type model is also based on UV photo spectrometer principle. In this system pump is installed inside the sampling section which is used to take the sample line. After periodic sampling the Flow cell of the system is automatically cleaned.


The interface is user friendly and works seamlessly. When the system is switched on the system is powered up and HMI display starts automatically. Further configured parameters are shown on the display.


Real time Monitoring provides continuous measurement of Data for long period of time. All the measure steps like collection, sample analysis, cleaning and calibration procedure are fully automated in this kind of monitoring. Historical data is saved upto 2 years on servers.


Effluent Quality Monitoring System/Analyzer facilitates the data compliance to the Government regulatory bodies. So that they take corrective action depending upon the data inputs available to them.
