DESIGN QUALIFICATION FOR PURIFIED WATER STORAGE & DISTRIBUTION SYSTEM

 FOR PURIFIED WATER STORAGE & DISTRIBUTION SYSTEM

The Purified Water from the upstream generation System is stored in a Vertical Jacketed Storage tank From the storage tank the water is then supplied to various user points in the Production area. The Purified Water storage tank is controlled with the help of a capacitance-type level transmitter, which performs necessary actions to maintain sufficient water level in the tank. The distribution loop consists of a distribution pump, and online instruments for measuring conductivity, Temperature, Pressure, and level to monitor the level in the storage tank. All the user point valves are Manual Diaphragm valves. Whenever the circulation loop is to be sanitized for the destruction of bio-film formation or as per Validation requirements, the water is heated and circulated at elevated temperatures (i.e + 85 degrees Celsius) for a while. During sanitization, the inlet-actuated diaphragm valves feeding to the tank are closed so as not to allow additional fresh water until sanitization is over.

INTRODUCTION

United States Pharmacopoeia (USP) has revised the water specification for purified water in their revised monograph USP for the Pharmaceutical Industry.

  • Conductivity: < 1.3 Microsiemen / cm at 25 ° C
  • TOC : < 500 ppb
  • Total Bacterial Count: < 100 cfu / ml

However, the system is designed considering USP-40 as the basis for specified parameters as Maximum Allowable Parameters at the user point with suitable Design Limits, Alert Limits, and Action Limits as specified in the subsequent clauses.

OBJECTIVE:

The objective of preparing a Design Qualification Document is to prepare design data and detailed specifications for all major components of the equipment and system for the agreed scope of supply and performance to ensure Customer Requirements are achieved for the project as per agreed specifications.

SCOPE

The Design Qualification is an essential part of the qualification process and will serve as a basic document for the validation activity. The scope of this document is to illustrate the complete design of an Integrated Scheme for the Storage and Distribution of Purified Water as per the Relevant Standards, Agreed Technical Specifications, User Requirement Specification (URS), and other finalized terms and conditions.

SYSTEM DESCRIPTION

  1. Storage & Distribution System up to User Points :(Ref P&I Diagram – _____________________)
  2. Automation and Data Acquisition

Ambient Storage and Distribution System with Hot Water Sanitization

The Purified Water from the upstream generation System is stored in a Vertical Jacketed Storage tank. From the storage tank, the water is then supplied to various user points in the Production area. The Purified Water storage tank is controlled with the help of a capacitance-type level transmitter, which performs necessary actions to maintain sufficient water level in the tank. The distribution loop consists of a distribution pump, and online instruments for measuring conductivity, Temperature, Pressure, and level to monitor the level in the storage tank. All the user point valves are Manual Diaphragm valves. Whenever the circulation loop is to be sanitized for the destruction of bio-film formation or as per Validation requirements, the water is heated and circulated at elevated temperatures (i.e + 85 deg Celsius) for some time. During sanitization, the inlet-actuated diaphragm valves feeding to the tank are closed so as not to allow additional fresh water until sanitization is over. The signal to this actuated valve is given by a PLC-based control panel. Detailed control logic is described in a later chapter.

The control panel supplied for the Purified water system consists of Controllers for instruments and other ancillaries. The control panel controls the operation of all automatic valves and pumps with a predetermined logic. In normal operating conditions, A minimum velocity of 1 m/s is maintained in the loop at peak consumption.

CRITICAL SAFETY REQUIREMENTS

  1. UV system functions are very critical for the performance of the overall system and the required intensity is to be maintained.
  1. On the compound pressure gauge showing less than zero kg/cm2, the cartridge of the vent filter to be replaced or sanitized.
  1. Periodic Sanitization of the system is very critical for the performance of the overall system and the required Frequency is to be maintained.

SAMPLING PLAN

Sampling Points as per following are provided:

S1: At the drain of Tank T-2101

S2: : At the outlet of Pump P-2101/02

S3:  At the inlet of UV – 2101

S4:  At the outlet of UV – 2101

S5: :  User Points

S6:  :  User Points

S7:  In return line after FT – 2101

SANITISATION CYCLE

PURIFIED WATER DISTRIBUTION SYSTEM:

The Sanitization of the Purified Water Distribution System shall be established based on Performance Validation. Storage and Distribution System shall be sanitized by Hot Water at 80-900C. It is preferable to sanitize the system once a week or as established during Performance Validation.

The complete system is designed for periodic sanitization.

Bio-film formation in the Distribution loop is an unavoidable phenomenon. As and when the microbial count is found to be exceeding the permissible limits, sanitization of the system shall be performed.

Whenever the circulation loop is to be sanitized for the destruction of bio-film formation or as per Validation requirements, the panel should be operated in the SANITIZATION MODE. The purified water tank is filled up to 1/3rd of its capacity.

During sanitization, the inlet valve feeding to the tank should be in the closed position so as not to allow additional fresh water until sanitization is over. Low-Pressure steam is used to heat this water. The LPST is passed through the jacket of the tank. Since the loop will be under continuous re-circulation, restricts the temperature to rise gradually. The water is heated up to 80-85 deg and then maintained at that temperature for an hour. Sanitization temperature and time, both are settable parameters. Steam inlet actuated globe valve KV-2102 opens and closes, depending upon the return line temperature sensor TT-2102. After the set time of sanitization is over, the water is circulated till it reaches to appropriate safe temperature by natural cooling. Then this water is drained out. Keep the sanitization mode switch in the OFF position and the PLC control system from Auto mode to Manual mode and charge enough fresh water in the tank to re-circulate through the Loop for 30 minutes to bring down the complete system to ambient temperature. Flush water from all sample and user points of the distribution loop as mentioned above in section 10.0 for 5 minutes. Completely drain the water from the Distribution Loop. Keep the PLC control system from Manual mode to Auto mode. Now the system is sanitized and ready for usage.

FACTORY ACCEPTANCE TEST:

  • All the equipment and systems covered in the system shall be offered for inspection at the works as per the agreed schedule and inspection requirements for Dimensional checkups and surface Finishes.
  • Distribution piping shall be offered for inspection, if required, before dispatch for a physical check-up for dimensions, workmanship, specification compliance, etc.
  • Prior approval for Inspection shall be given for the items required to be inspected. In case of -feasibility of inspection, the waiver of inspection shall be provided authorizing the dispatch.

After FAT the approved and accepted material shall be dispatched for site erection.
