Study Notes

Standard Operating Procedure (SOP) for Water Analysis

  • Title: Specifications and Chemical, Physical Analysis Methods for Raw and Purified Water in Normal Production
  • SOP Number: QC-008E
  • Effective Date: 30/08/2022
  • Document Revision: Every 3 years or as needed
  • Company: Modern Company For Drugs Industries (MDI)

Table of Contents

  • History: Page 2
  • Purpose: To analyze raw and purified water according to analysis methods and specifications
  • Scope: Applies to raw and purified water testing in normal production
  • References: MDI's internal SOPs
  • Abbreviations and Definitions: Lists various abbreviations used in the SOP (e.g., SOP, MDI, QA, QC, µs, NTU, mg/l, Max, Ref)
  • Procedure: Page 3, detailed steps for chemical and physical analysis of raw and purified water
  • Responsibility: Outlines responsibilities of different personnel (Quality Control Analyst, Quality Control Manager, Engineering Manager, and Quality Assurance Manager) involved in water testing and quality control
  • Documents Revision: Page 9, lists the different revisions of the document and the dates

Procedure Details (Partial)

  • Sample Preparation: Collect samples from various sections; allow water to drain for 2 minutes for purified water; Collect samples from raw water sources.; Rinse bottles with sample water three times before filling
  • Testing Methods (Examples): Daily tests for purified water include appearance, odor, color, pH, conductivity, TDS, turbidity, and total chlorine. Weekly tests include ammonia, iron, calcium hardness, magnesium hardness, sulfate, and TOC
  • Instrument Calibration: Calibration is required for pH, turbidity, and sulfate tests using standard solutions.
  • Results: Results are documented in logbooks (Appendix-1 and Appendix-2)
  • Frequency: Raw water testing is monthly; Purified water testing differs according to usage and purpose (daily, weekly).

Water Specifications (Examples)

  • Purified Water: Colorless, odorless, clean liquid
  • Raw Water: Specifies parameters like color, odor, taste, turbidity, pH, conductivity, sulfate, ammonia, total chlorine, calcium hardness, magnesium hardness, iron, total dissolved solids, and total organic carbon
  • Values Provided: Maximum permissible values for each respective parameter are given for both raw and purified water

Appendices
