Standard Operating Procedure for Cleaning of Filtration Systems

1. Purpose

The purpose of this Standard Operating Procedure (SOP) is to outline the cleaning procedure for filtration systems used in pharmaceutical manufacturing to ensure product quality, safety, and compliance with Good Manufacturing Practices (GMP).

2. Scope

This SOP applies to all personnel involved in the cleaning of filtration systems within the pharmaceutical manufacturing facility.

3. Responsibilities

Production Operator: Responsible for initiating the cleaning process.
Quality Assurance (QA) Inspector: Responsible for verifying the cleanliness of the filtration systems and approving them for further use.
Supervisor: Oversees the cleaning process and ensures compliance with this SOP.

4. Procedure

4.1. Pre-Cleaning Preparations

Notify the Production Supervisor of the need for filtration system cleaning and obtain necessary approvals.
Ensure that the filtration system is not in operation and is safely isolated from the production process.
Wear appropriate personal protective equipment (PPE), including gloves and safety goggles.

4.2. Inspection

Visually inspect the filtration system for any visible contaminants or clogs in the filter media.
If any contaminants or clogs are found, note their location and severity for documentation.

4.3. Disassembly (if applicable)

If the filtration system has removable parts (e.g., filter cartridges), follow the manufacturer’s instructions for disassembly before cleaning.

4.4. Pre-Rinse

Rinse the filtration system with purified water to remove any visible contaminants.
Use a soft brush

or sponge to gently clean the surfaces of the filter media if necessary.

4.5. Cleaning Solution Preparation

Prepare a cleaning solution as per the approved formula and concentration. Refer to the Cleaning Solution Formulation document (if available) for details.
Ensure that the cleaning solution is suitable for the materials of construction of the filtration system and compatible with the filter media.

4.6. Cleaning Process

Apply the prepared cleaning solution to the surfaces of the filtration system, including the filter media, using suitable cleaning tools.
Allow the cleaning solution to contact the surfaces for the specified duration as per the cleaning procedure.
Rinse the filtration system with purified water to remove residual cleaning solution.
Repeat the cleaning process as necessary until all contaminants and clogs are removed.

4.7. Post-Cleaning Inspection

Visually inspect the filtration system after cleaning to ensure that all contaminants and clogs have been effectively removed.
If any contaminants or clogs persist, repeat the cleaning process.

4.8. Reassembly (if applicable)

If disassembled, follow the manufacturer’s instructions for reassembling the filtration system and its components.

4.9. Final Inspection and Approval

Notify the QA Inspector that the filtration system is ready for inspection.
The QA Inspector will visually inspect the system and document the inspection results.
If the system meets cleanliness criteria, it is approved for further use. If not, the cleaning process is repeated.

4.10. Documentation

Properly document the cleaning process, including cleaning dates, personnel involved, cleaning solutions used, inspection results, and any deviations from the procedure.

5. Abbreviations

GMP: Good Manufacturing Practices
PPE: Personal Protective Equipment
QA: Quality Assurance

6. Documents

Cleaning Solution Formulation – Document specifying the approved cleaning solution formula and concentration.
