Q: When should membrane elements undergo cleaning?
A: It is crucial to clean the membrane elements under these conditions:
When you notice a marked reduction of 10-15% in normalized permeate flow, it's time for a cleaning.
A significant increase of 10-15% in normalized permeate total dissolved solids (TDS) indicates the need for cleaning.
A substantial rise of 10-15% in the normalized pressure drop between the feed and reject streams signals the need for cleaning.
Q: What are the steps to resolve RO membrane blockage?
A: 1. Begin by verifying if the membrane in your home RO system is indeed blocked.
2. Assess the local water quality, focusing on whether calcium and magnesium salts are the primary scaling components.
3. Prepare a cleaning solution with 10% hydrochloric acid or a commercially available descaling detergent, combined with a specialized RO membrane cleaning agent, based on the scale composition. Soak the RO membrane for a complete 24 hours.
4. After the soak, thoroughly rinse the RO membrane using water produced by ultrafiltration. Ensure the pure water outlet is closed and the wastewater outlet is open to achieve effective flushing.
Q: Why does RO membrane blockage occur within one to two months?
A: 1. High salt content in the raw water leads to excessive scaling, resulting in blockages.
2. Elevated levels of organic matter in the water surpass acceptable standards, leading to RO membrane fouling and subsequent blockage. This can compromise the performance of the system, necessitating timely intervention to maintain optimal functionality.
3. This remarkable RO film features an outstanding recovery rate, guaranteeing optimal performance and maximizing efficiency. Its innovative design ensures that you enjoy high-quality filtration with minimal waste.
4. A notable drawback of the purifier is the absence of a flushing function. This limitation results in the buildup of high-concentration brine over time within the RO membrane shell, which may adversely affect its longevity and performance. Regular maintenance is essential to mitigate these effects and ensure the continued effectiveness of your purifier.
