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

Latest Projects

Electrochlorination

Electrochlorination is the process of using salt, water and electricity to produce a low pH Sodium Hypochlorite solution directly on site. It is highly efficient because the system can respond to the levels of free chlorine in the water and apply dosing only when required.

Our range of AMPRO electrochlorinators are ideal for many of these applications and come with a full after sales support package. These machines are ideal for small footprint systems and have features such as integral hydrogen degassing, making them safer for installation by third parties.

Our advice is impartial, and we won’t advise a course of action or recommend a piece of equipment unless we know it offers a genuine benefit to your process.

Chlorine Dioxide Generators

Chlorine dioxide is, quite simply, a more powerful oxidising agent than chlorine in every way. It works better as a disinfectant and has the advantage of also breaking down odours.

If you think a Chlorine Dioxide generator might be the best way to go, it is worth getting the benefit of our advice first. We are not on commission and have no interest in selling devices unless they are the most appropriate and effective option for your particular process.
