PCCell PC Frontend app

Electrodialysis process control


Our ED Systems are operated via our PC Frontend. It consists of a software package to read and store the data from the plot unit. It visualizes the state of the unit on runtime and stores its data into a file for later use. The program is subdivided into tabs, which can be chosen by selecting the appropriate register at the top. Within these tabs, different adjustments can be made or plots of measuring values can be viewed.

The PCCell PC Frontend


PCCell PC Frontend app operate the electrodialysis systems by a graphical display with touch panel. We provide the PC Frontend in a table panel module or implemented in the skid of an industrial system or on a small removable convertible PC.

The PC Frontend hardware (Fig. 2, red part) is integrated in a small measurement box, in the electrodialysis table panel or in the basic electrodialysis system to operate the electrodialysis system (black part). Each PC Frontend is specifically customized according to the individual requirements and existing measurement devices.

Functions of the PC Frontend app


Main features of the PC Frontend app:

  • Operation of pumps, power supplies and valves.
  • Visualization of measured values: Current, voltage, conductivity, temperature, flow, pressure and pH (provided by standard and optional sensors).
  • Visualization of calculated values (charge, concentration).
  • Display of the process values in dependence of time or charge.
  • Features during operation:
  • Storage of freely definable events with a time stamp.
  • Input dialog to store and display experimental values (e.g. volume).
  • Semi-automatic batch processing with user-defined end points (conductivity, pH).
  • Automatic stabilization of parameters (pH, conductivity) by operation of a dosing pump.
  • Calibration of sensors (e.g. pH probes), guided by calibration menus.
  • Reporting and evaluation:
  • Export of generated graphs as individual graphic files (.png format).
  • Storage of measured parameters in a log-file (.csv/.txt format).
  • Storage of the logged events, changed calibration factors and automatically generated events in a separate event-log-file for documentation and further analysis.
  • Automatic generation of a report of the experiment or process run (.rtf and .pdf format).
  • The log-file can be imported into the PC Frontend app any time after termination for further evaluation, generation of graphs, or for continuation of the experiment.

  • Process Visualisation and Control of Parameters

    All process measured parameters (current, voltage, conductivity etc.) and manually obtained experimental values (volume levels, flows, valve- and pump-status) are displayed in the process visualization view (Fig. 3) online during the experiment on a P&I chart. The trends of the relevant parameters are displayed as graphs (Fehler: Referenz nicht gefunden) in dependence of time or charge. Pumps, power supplies and all other components are operated from the PC Frontend app via buttons. The PC Frontend provides a principal time axis (internal experimental time) starting once the data acquisition is started. The time unit can be chosen to be seconds, minutes or hours. A second timeline (“ED run”) can be initialized individually and the plots are displayed with this time axis. At the end of the ED run, a short report is generated summarising the charge and time during the run. The software automatically logs different events with its time stamp during a process run (Fig.4) into an event-log-file and shows its content in the event-list field. Important notifications (eg. observation of precipitation color changes etc.) can be documented in the log-file by a dialog sequence.
