Quality Selected 10-Ton Pharmaceutical Purified Water Equipment Maintenance

# Maintenance of 10-Ton Pharmaceutical Purified Water Equipment 

 ## I. Introduction Pharmaceutical purified water equipment holds a crucial position in the pharmaceutical industry. Its stable operation and excellent performance are key factors in ensuring drug quality. For 10-ton pharmaceutical purified water equipment, scientific and reasonable maintenance can not only extend the equipment's service life but also ensure the continuous and stable production of purified water that meets quality standards. 

 ## II. Daily Maintenance

 ### (1) Exterior Cleaning Clean the exterior of the equipment daily to remove surface dust, stains, etc. Use a clean, soft cloth to wipe the equipment casing. For stubborn dirt, a mild cleaning agent can be used, but avoid allowing the cleaning agent to enter the interior of the equipment to prevent damage to internal components. Simultaneously, inspect the equipment's exterior for any damage or deformation. If issues are found, record and address them promptly.

 ### (2) Instrument Inspection Check various instruments on the equipment daily, including pressure gauges, flow meters, conductivity meters, etc. Ensure the instrument readings are clear and accurate. If abnormal instrument displays are observed, such as needle fluctuations or significant reading deviations, calibrate or replace the instruments promptly. The proper functioning of these instruments is vital for monitoring the equipment's operating status and the quality of the purified water.

 ### (3) Valve Inspection Inspect various valves in the equipment, including inlet valves, outlet valves, return valves, etc. Ensure the valves open and close flexibly without any leakage. For manual valves, the operating handle should be intact; for electric valves, check that the control circuits and motors are functioning properly. If abnormal noises or operational difficulties occur, repair or replace the valves promptly.

 ## III. Periodic Maintenance 

### (1) Filtration System Maintenance 1. **Multi-Media Filter** Backwash the multi-media filter every 1-2 weeks. During backwashing, control the intensity and duration to effectively remove impurities from the filter media surface without causing loss of filter media. Every 3-6 months, inspect the condition of the filter media and replenish or replace it if necessary. 2. **Activated Carbon Filter** Similar to the multi-media filter, the activated carbon filter requires periodic backwashing, typically every 1-2 weeks. Additionally, due to the limited lifespan of activated carbon, check its adsorption performance every 6-12 months and replace it as needed to ensure effective removal of organic matter, residual chlorine, etc. 3. **Precision Filter** Check the pressure drop across the precision filter cartridge weekly. Replace the cartridge promptly when the pressure drop exceeds the specified value. Generally, replace the cartridge every 2-3 months, and clean the interior of the filter during replacement.

 ### (2) Reverse Osmosis System Maintenance 1. **Membrane Elements** Chemically clean the reverse osmosis membrane every 2-3 months. Select an appropriate cleaning agent based on feed water quality and operating conditions, and strictly follow operating procedures during cleaning to avoid damaging the membrane elements. Regularly check the salt rejection rate and water production of the reverse osmosis membrane. If significant declines are observed, analyze the cause, as further cleaning or replacement of the membrane elements may be necessary. 2. **High-Pressure Pump and Booster Pump** Monthly, inspect the pump's operating sound, vibration, and sealing performance. Check the level and quality of the pump's lubricating oil, and replenish or replace it as needed. Regularly monitor the pump's inlet and outlet pressures to ensure it operates within the normal pressure range. ### (3) Disinfection System Maintenance For disinfection devices in the equipment, such as ultraviolet sterilizers and chemical disinfection units, check their operating status monthly. For ultraviolet sterilizers, inspect the UV lamp's light emission and replace it promptly if damaged; for chemical disinfection units, check that the disinfectant concentration and dosage are normal.

 ### (4) Pipeline System Maintenance Quarterly, inspect the equipment's pipeline system, including checking for loose connections and leaks. For stainless steel pipelines, inspect the surface for corrosion; for circulation pipelines, ensure they are unobstructed to avoid dead legs and stagnant areas that could promote bacterial growth.

 ## IV. Long-Term Maintenance 

### (1) Comprehensive Equipment Inspection Conduct a comprehensive annual inspection and maintenance of the equipment. This includes detailed checks of the electrical system, control system, mechanical components, etc. Inspect the insulation of electrical wiring and the working status of contactors and relays; calibrate and test the control system's PLC and sensors; lubricate and tighten mechanical components as needed.

 ### (2) Storage Maintenance If the equipment needs to be out of service for an extended period, drain all water from the equipment. After cleaning and disinfecting the equipment, apply appropriate protective measures, such as applying rust inhibitors to key component surfaces, and store the equipment in a dry, well-ventilated environment to prevent rust and other damage. ## V. Conclusion Maintaining 10-ton pharmaceutical purified water equipment is a systematic and meticulous task that requires operators to strictly follow maintenance procedures for daily, periodic, and long-term upkeep. Only in this way can the equipment's normal operation be ensured, providing high-quality purified water for pharmaceutical production and safeguarding drug quality and safety.
