PROJECT: USP PURIFIED WATER SYSTEM Page 1 of 16

PROCESS OVERVIEW

Cold city water is supplied at 21 gpm through a multi-media filter for the removal of large micron particulates. Filtered city water passes to duplex alternating softening tanks for removal of calcium, magnesium and other cations from the city water. Water softeners are sized for 1-1/2 days of softening capacity per tank (2.4 mil grains) at peak consumption. The multi-media filter backwashes based on time. The water softeners regenerate and alternate automatically based on total throughput.

Softened water passes into a hot water sanitizable carbon filtration system for the removal of chlorine, reduction of TOCs / chloramines and particulates to 1 micron in size. The carbon loop uses a circulation pump to transfer water continuously through a 5 micron pre-filter, carbon tank, 1 micron pre-filter, circulation heater, and break tank. The carbon loop is designed for periodic sanitization using hot 80-85 °C water. During the sanitization process, contaminates will be released from the carbon filter. Flush valves are provided at the inlet of the downstream break tank to prevent these contaminates from fouling the RO/EDI loop and associated components. The carbon tank backwashes based on time.

Treated water from the pretreatment and carbon filtration system fills a RO/EDI Loop Break Tank. The break tank is sanitary in design and equipped with a sterile vent filter, level controls, and return line spray ball. Water that fills the break tank is blended with unused purified water. The break tank is incorporated as part of the purified water generation loop.

Water from the break tank supplies water to the reverse osmosis system. A boost pump generates flow and pressure through high temperature RO membranes. To increase system recovery, a portion of the concentrate water is recycled back to the RO pump. Design recovery is 75%. The membranes will reject


95-98% of ionic contaminates. In addition, organics will be reduced to specifications based on molecular weight. The RO will operate continuously and reject 3-4 gpm of concentrate water.

Permeate water from the RO feeds a single high temperature EDI module. The EDI module uses a combination of membrane and resin technologies to reduce the ionic content in the water to desired levels (0.5-0.06 µS/cm). A 600V electrical source from the control panel is used to regenerate the resin resulting in a continuous deionization process. To conserve water, the concentrate from the EDI module is returned back to the break tank.

Pure water from the EDI module passes through a UV lamp and final filtration system. The UV lamp will deactivate microbes using 254-nm UV light. The absolute rated final filters capture the deactivated microbes. Water that passes the final filters meets the specifications for USP Purified Water.

USP Purified Water is supplied through an owner supplied piping system to a USP Purified Water Storage Tank. A series of divert valves mounted on the storage tank are interfaced to the water skid control system. Water fills the tank based on a level signal from the owner supplied tank level transmitter. Unused USP Purified Water is returned back to the break tank through an electric circulation heater and chilled water cooling exchanger. On-line conductivity and TOC monitor will verify water quality.

The RO/EDI loop is design to be sanitized using hot 80-85 °C water circulated at low pressure and flow rate through each of the components. During the sanitization process, contaminates will be released from the RO membranes. Flush valves are provided at the inlet of the EDI module to prevent these contaminates from fouling downstream components.

The system has a fault/alarm indicator and automatic shutdown based on operator programming for the severity and type of fault. The system is operated by an independent PLC and normally operates automatically. A "ladder-logic" program, runs through an Allen-Bradley SLC 5/05 programmable-logic controller (PLC), controls the operation of the equipment. An Allen-Bradley Panel View 1000 operator-interface terminal (OIT) is provided for the system monitoring and configuration. Set points, delay times, and PID loop parameters can be changed via the OIT (access to configuration screens is limited with security measures).

The operator interface is an Allen Bradley Panelview 1000 screen with an Ethernet communication port. The OIT will communicate with the PLC via the Ethernet port using an Ethernet protocol. The OIT will allow the users to view process data, enter setpoints and change control states. The main control panel door will also contain conductivity meters displaying system information.

The control system will automatically control the pumps and automatic valves on the system for a seamless continuous operation of the system. The control system will also control the operation of the two purified water supply and divert valves (owner installed - as depicted in the overall system schematic). Connection of pneumatic lines from the valve is provided.

The OIT will use a series of screens to navigate the system controls. The OIT screens will provide for operations monitoring, operator interface, alarm monitoring and alarm summary, and system diagnostics. The operations screens will indicate the operating parameters and status of the equipment. Operators will have the ability to set timers, change timers, control and change flow rates and controller set points, and select sanitization recipes from the main control panel. Operator interface screens will enable the operator to operate the equipment via programmable function keys and input selected numeric data. The diagnostics screen(s) shall provide status of critical inputs and outputs.

The system will include continuous alarm monitoring. Critical alarms will result in a safety interlock requiring operator action. The operator will be required to acknowledge the alarm before the alarm can be reset and the system restarted. All alarms will be displayed on the alarm summary page. When any alarm is reported, the PLC will generate a signal to an audible device on the control panel. Audible alarms will be silenced on the OIT. The operator interface will be provided with a restart button to restart the equipment for operation after alarm clearance. Sanitization sequences will restart from the point of alarm.


The control system will be fully 21 CFR Part 11 compliant. Software automation shall be deployed to achieve Part 11 compliance wherever practical. Compliance validation is a customer responsibility.

QPS will be responsible for the development and the execution of the FAT document. The owner will be given the opportunity to witness and/or participate in the FAT execution at their discretion. A schedule of FAT execution activities will be developed and maintained by QPS.

During the execution of the FAT, QPS will conform to good documentation practices. This includes, but is not limited to, using indelible ink for data recording, signing and dating all data entries at the time they are recorded, using a single line strike out that is initialed and dated for all data entry errors, and providing explanation for line-outs that do not have an obvious reason. It is the intent of this project that some testing conducted and documented in the FAT may not be repeated once the system is installed at the owner site.

A formal deviation recording process will be described in the FAT document. The deviation process will describe what actions and sequences take place when data is recorded that does not conform to the acceptance criteria or expected results. The process of recording deviations, informing the appropriate personnel, determining corrective actions, determining dispositions, closing out, and final approval will be described.

Calibrated instrumentation traceable to the National Institute of Standards and Technology (NIST) will be used. Copies of all calibration certificates shall be turned over with the completed FAT document. At the conclusion of the FAT, the originally approved document, the completed data sheets, and all referenced documentation and attachments shall be submitted to the owner’s designated agent for their acceptance.

SITE ACCEPTANCE TESTING (SAT)

At the owner’s discretion, all or some of the tests performed during the FAT will be repeated at the jobsite. QPS will demonstrate the complete functional integration of all of the components of the water system.
