Instrumentation and Control
Instrumentation and controllers are fundamental to our ability to control water treatment processes. It is through the use of reliable and accurate instrumentation that monitors key parameters within the water that we are able to provide information back to the controllers that in turn govern the process.
Many disinfection processes are based on the use of chlorine which can be controlled by the monitoring of the level of free or total chlorine within the water. Prodose are able to offer either amperometric with bare electrode which offer both accuracy and quick response times for free or total chlorine measurement or Ion selective residual analyser for process parameters for Free Chlorine, Total Chlorine, Chlorine Dioxide and ozone.
With a range of single parameter and multi-parameter controllers Prodose are able to supply instrumentation and control systems to meet the most difficult of disinfection control applications.
Prodose Controllers
Precise control of disinfection processes requires instrumentation capable of monitoring the chemical residual levels within the water. Having a residual of chlorine or chlorine dioxide ensures that there is a constant excess of disinfectant within the water system.
Our instrumentation and control systems use highly calibrated, multi-probe technology to precisely monitor and report on specific residual levels in the water system.
The system generated reports are fully auditable and run continually to produce comprehensive data feeds for analysis.
Benefits
- 5 measuring cell and up to three additional sensors
- Four different selectable control types, together with automatic set-point adjustment
- Time-controlled dosing using programmable time switch contacts
- Easy to configure with selectable, preset process-adjusted applications
- Easy linking with process visualization systems via an OPC server; with Process Monitoring System connected to Web technology
- Additional functions such as integrated calibration instrument bracket, easy draining of the flow block module, sample water extraction
Membranes
Membranes
Membrane sensor measuring modules for free chlorine, total chlorine, chlorine dioxide and ozone consist of a plug-in sensor card and a particular membrane sensor.
Benefits
- Safe, long-term stable
measurement system - Integral temperature
compensation - No reagents required
Benefits for free chlorine
- Continuous, on-line measurement
of free chlorine even at high pH
(up to pH 10) and at low conductivity
(from 10 μS/cm on) - Ideal for samples with varying pH
(internal buffering)
Typical applications
- Measurement and control in industrial and municipal water treatment
- Process measurement, final inspections, neutralization plants
- Monitoring of potable water, well water, pool water, boiler feed water
