Water Waste Treatment Monitoring System

Industry

Pharmaceutical

Business Issue

The Waste Water Treatment system included many remote field devices that were monitoring the status of the various waste water treatment tanks.  Due to the remote location of the devices and lack of centralized notification of the alarms, alarmed conditions were not readily identifiable and resulted in delayed corrective actions.  This was a particular problem during non business hours.

Project Summary

The Waste Water Treatment System is a PLC based system which monitors specific parameters of the waste water treatment system such as well level, pH values, Ammonia concentrations, temperature, UV transmittance, flowrates. The system initiates alarms when these parameters are out of limit including providing notification to remote locations during critical alarm conditions through a paging system.
