English Abstract
Most of existing Water Treatment Plants (WTP) in Iraq are old, and the adopted traditional operating mechanism does not keep pace with the current technological developments in control and supervision systems.
The existing control and monitoring systems are run manually, which include manual collecting and examining of water samples in addition to manual operation and monitoring of the treatment equipments through local control panels located near the equipments.
The manual control of some operations, such as changing alum or chlorine dosages are generally inefficient, because of the lake in continuous monitoring of raw and treated water quality and lag time between taking and examination of samples.
This will cause delay in taking the necessary action to correct the doses of the chemicals added to water treatment.
In order to upgrade the control and operation techniques of WTP in the country, through the introducing supervisory control and data acquisition expert control systems (SCADA) which are universally applicable, Sharq Dijla WTP with its first and second extension has been taken as a model to study and upgrading.
This had been done by preparation a model to develop the plant operation by using automatic control systems with continuous analyzing and monitoring instrumentations.
In which, all the physical and chemical variables of raw and treated water will be measured and automatically controlled to achieve an effective and continuous control and monitoring.
One of the most important components suggested to be used in the automatic control systems are the programmable logic controllers PLCs.
WTP would be automatically controlled depending on set of input data from continuous monitoring and analyzing devices.
The PLC operates automatically the treatment units to ensure the safe and stable conditions depending on obtained data and the PLC control program.
The structure of control and supervision that have been proposed for the plant, provide multiple abilities to control and monitor the treatment processes.
Beside the ability to control the treatment plant automatically, the control and monitoring can be manually achieved either locally through local control panels or remotely through the operator control and monitoring device in the operator workstation.
