Remote Telemetry Management and Monitoring

Much of the monitoring and control of each wastewater treatment plant will be carried out remotely using telemetry features built into the programmable control panel. The Orenco Systems® microprocessor-based controller in the panel integrates with standard control panel components (motor contactors, etc.) and provides digital and analogue sensor inputs as well as a two-way dialup function via a modem. This means that the Service Company maintaining the system can receive remote alarm callouts. For example a high level alarm could trigger the system to call the Service Company office, or a pager. The system can then be checked remotely from the office to simplify troubleshooting, and facilitate accurate analysis and reduce costly call outs.

System elements can also be controlled remotely (e.g. pumps turned on/off) allowing quick response and early preventative maintenance. This could involve reprogramming the control panel remotely to by-pass a float switch until a local contractor can be sent out to attend the situation.

Standard logging and trending of data are also possible. Any type of event log can be captured and stored, or programmed to trigger an alarm event. This includes pump run-times, high-level alarms, low-level alarms, daily effluent flows, pipe or orifice pressures, and oxidation-reduction potential.

Data can be stored for several years depending on input volume and report requirements. Reports can be viewed remotely or downloaded into common data management programmes (e.g. Microsoft Excel) for manipulation. The data can be electronically forwarded to the relevant consent/regulatory authorities.

The RTU panel aids remote troubleshooting and monitoring for better maintenance and operational efficiency.
