Active Carbon Filter, Purpose:
Active Carbon Filter, The purpose of this SOP is to define the procedure of sanitization of Active Carbon Filter, RO and EDI of Purified Water Generation Plant manufactured by Watertown in order to ensure its smooth & trouble-free operation and generation of qualified purified water.
Active Carbon Filter, Scope:
This Standard Operating Procedure applies to the PW plant manufactured by Watertown, which is located at the Utility area (roof top) of Solid Block of XX Pharmaceuticals Ltd.
Definitions / Abbreviation:
[][]SOP: Standard Operating Procedure.
[][]PW: Purified Water.
[][]HMI: Human Machine Interface.
[][]ACF: Active Carbon Filter.
[][]RO: Reverse Osmosis.
[][]EDI: Electro De Ionizer.
Responsibilities:
[][]The roles and responsibilities are as follows:
Engineering (Validation) Department
[][]Preparing the SOP and revise it when necessary.
Engineering (Operation & Maintenance) Department
[][]To provide necessary support for smooth operation of the system.
[][]To ensure that the operators are responsible to carry out the operation and fill up the logbooks.
Operators
[][]To sanitize the ACF, RO and EDI according to the SOP.
[][]To fill up the logbooks.
Manager, Engineering
[][]To ensure that the operation of PW plant are done properly.
Manager, Quality Assurance
[][]To approve the SOP.
[][]To ensure overall implementation of this SOP.
Procedure:
Precautions:
[][]All operation work must be done safely in accordance with the requirements of the Plant Safety Statement and the safety notices around the plant. Specific attention must be paid to the following:
[][]Use Personal Protective Equipment during handling of any kind of chemical.
[][]Be sure that the steam line is insulated.
[][]Do not touch the hot water pipe line with bare hands.
[][]Check that there is no leakage in the steam or hot water line.
[][]Ensure all the utilities before doing any operation.
[][]Ensure that the water level in the water storage tank is at least 35%.
Framework Description:
[][]The PW plant made by Watertown has a limit of 3000 L/hr. The plant has Raw water pretreatment and RD/EDI areas.
[][] In pretreatment segment crude water is sifted through MGF and ACF separately.
[][] Then, at that point, this crude water is gone through the conditioner to lessen the hardness and is at long last treated with the RO and EDI to get the refined water of wanted determinations.
[][]The disinfection of ACF, RO and EDI is finished by utilizing heated water at a temperature of around 80°C.
[][] There are two hotness exchangers in pretreatment area and RO/EDI segment to create the boiling water with the assistance of modern steam.
[][]After disinfection of RO and EDI cooling is done at a temperature of 30 ± 5°C.
Automatic Sanitization Procedure:
Sanitization of ACF:
[][]Close the manual butterfly valve V47-03.
[][]Switch on the main breaker to supply electrical power of the plant.
[][]Ensure compressed air and other utilities to run the plant.
[][]The HMI becomes ON and following screen will appear.
Press Enter on that screen.
[][]Then the following screen will appear. Press “Parameter setting**” button to check the parameters sanitization and a box will appear for user ID and Password.
[][]Then the following screen will appear to see the parameters. Press “setting2” to see the other parameter settings.
[][]Then the screen will appear.
[][]Press the “Exit” button to go to the menu navigation page
[][]Press the “sanitization***” button and give user ID and password to go to the sanitization page.
[][]In the sanitization page press the “Auto ON” button for Automatic operation.
[][]In the sanitization page press “Carbon filter Sanitization” for sanitization of ACF.
[][]Then the following screen will appear. Press the “Carbon filter Sanitization OFF” button to start the sanitization automatically. Normally the sanitization temperature is approx. 80°C for a period of 60 mins.
[][]During sanitization fill up the operation log sheet (Annexure – I).
[][]Natural cooling procedure is used to cool the ACF after sanitization.
Sanitization of 1st stage RO:
[][]Close the manual butterfly valve V50-22.
[][]In the sanitization page (Figure 06) press the “RO I Sanitization” button. Then the following screen will appear. Press “RO I Sanitization OFF” button on that screen to sanitize the 1st stage RO automatically.
[][]The sanitization temperature of 1st RO is as 80 ± 3°C for 60 mins.
[][]After doing sanitization cooling is done at a temperature of 30 ± 5°C by flowing cooling water.
[][]Fill up the operational log sheet (Annexure – I) during sanitization.
Sanitization of 2nd stage RO:
[][]In the sanitization page (Figure 06) press the “RO II Sanitization” button. Then the following screen will appear. Press “RO II Sanitization OFF” button on that screen.
[][]Cooling procedure is as same as it is for 1st stage RO.
Sanitization of EDI:
[][]Close the manual diaphragm valve of bypass line of membrane contactor.
[][]In the sanitization page (Figure 06) press the “EDI Sanitization” button. Then the following screen will appear. Press “EDI Sanitization OFF” button on that screen.
[][]After sanitization RO and EDI are cooled down to 30°C ± 5°C by supplying cooling water.
[][]Fill up the operational log sheet during whole sanitization and cooling period.
