The SCADA system for water purification is designed to efficiently monitor and control the various processes involved in treating water. It allows operators to remotely access and manage the purification system, ensuring that water quality is consistently maintained. The system provides real-time data on water levels, flow rates, and chemical dosing, enabling quick response to any deviations from optimal operating conditions. With its user-friendly interface and advanced automation capabilities, the SCADA system enhances the overall efficiency and reliability of water purification processes.

Operation of SCADA System for Purified Water Plant

1.0   Objective

• • To lay down the procedure for the Operation of the SCADA System for Purified Water Plant.

2.0   Scope

• • This SOP is applicable in Engineering for the Operation of the SCADA System for the Purified water Plant at the pharmaceutical Drug Manufacturing Plant.

3.0   Responsibility

• • Water System operators/ Engineers : To follow the procedure
  • Head Engineering:    System Compliance

4.0   Procedure for SCADA System Operation

• • Start the Computer system & click the SCADA to open the software:

SCADA System – Pre-treatment Section (Figure – 1)

• • After the show as per Figure – 1 pl. check the below parameter.

• • All tanks shall be above half filled.

• • Ensure that the all valves are open.

• • The level of Dosing solutions tank i.e. Anti-scalent, SMBS, NaOH.

• • Ensure the parameter of ORP meter it shall be less than 300 mv.

• • If all parameter within the range then click on next option.

Figure – 2: SCADA System – RO Section

• The next stage is shown in Figure – 2 Check the parameter as per the below checklist.

• • Check the pressure of the pump for maintaining of flow of water. It shall be between 5-10 Kg/cm².

• • Check the conductivity of the R.O. water. It shall be less than 30 µs/cm.

• • If all parameters are within range then click to Next option.

SCADA System – MB Section (Figure – 03)

• The next stage is shown in Figure 3 for MB operation. Check the parameters as below checklist.

• • Ensure the valve setting as shown in Picture -03. If not, rectify the same.

• • Check the conductivity of water, After the Mix bed, It shall be less than 1.0 µs/cm.

• • Check the pH of the water. It should be between 5 to 7.

• • Ensure that Pump No. 1 & pump No. 2 are in auto mode.

• • Ensure the flow of water on 6 M³ / Hour at before the Mix bed.

Figure – 4:SCADA System – USP Section

• The next stage is shown in Figure – 4. Check the parameters below the checklist

• • Ensure the flow in the return loop at the flow meter & check the conductivity of the return loop.

• • It shall be less than 1.3 µs/cm.

• • Check the storage tank level of the purified water storage tank.

• • It shall be a minimum of 50% & maximum of 90%. If not in range, fill it.

• • Check the return loop of purified water velocity & green signal of the drain valve.

Figure – 5: Runtime Data

• For getting the window as per figure – 5.

• • Login to the operator’s log.

• • Then click the “GO TO MODE SELECTION” & select the normal mode for operation.

• • Printout of parameters shall be taken once in a day & after regeneration of the Mix bed.

• • The operator/engineer shall review the data & enclose it in the file after QA verification.

• • The alarm shall be reviewed by the operator/engineer verified by QA & shall be updated in Annexure-I.

• • The alarm shall be classified as critical and non-critical.

• • For example, if there is high conductivity at CT-02(return loop) or high value at ORP sensor etc shall be considered critical, and tank level high or tank level low, etc. shall be considered as non-critical, and the same shall be updated in Annexure.

• • Critical alarms shall be investigated as per the relevant SOP.

• • Check the temperature of the vent filter jacket at the time of sanitization. It shall be approx. 85 ºC.

• Auto dumping challenge test for high conductivity.

• • Reduce the conductivity limit to below the current observed value at CT-02 during the activity of the challenge test.

• • After setting check the opening of the dumping valve and the flow of water through the drain.

• • All activity shall be performed under the supervision of QA.

• • After completion of the challenge test reset the set value as per SOP and run the system.

• • Record the data in Annexure II.

• • The frequency for the Challenge test for the auto dumping valve in the water system shall be yearly ± 30 Days.
