Q: Is a single 1*400GPD system superior to a dual 2*200GPD setup? Explore the benefits and efficiency of these configurations.
A: Opting for the 200GPD system provides several advantages, such as reduced adhesive usage during manufacturing, significantly boosting salt rejection rates and enhancing water flow efficiency.
Q: When should membrane elements undergo cleaning? Identify the optimal times for maintenance and cleaning.
A: It is crucial to clean the membrane elements under these conditions:
A noticeable reduction of 10-15% in normalized permeate flow indicates it's time for cleaning.
An increase of 10-15% in normalized permeate total dissolved solids (TDS) signals the need for cleaning.
A rise of 10-15% in the normalized pressure drop between the feed and reject streams suggests cleaning is necessary.
Q: What are the steps to resolve RO membrane blockage? Follow this guide for effective solutions.
A: 1. Confirm that the membrane in your home RO system is indeed blocked to proceed.
2. Assess local water quality, focusing on calcium and magnesium salts as primary scaling components.
3. Prepare a cleaning solution with 10% hydrochloric acid or a commercially available descaling detergent, along with a specialized RO membrane cleaning agent, based on the scale composition. Soak the RO membrane for a full 24 hours.
4. After soaking, thoroughly rinse the RO membrane using water produced by ultrafiltration. Ensure the pure water outlet is closed and the wastewater outlet is open for effective flushing.
Q: Why does RO membrane blockage occur within one to two months? Understand the causes behind frequent blockages.
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, causing RO membrane fouling and subsequent blockage.
3. This remarkable RO film boasts an exceptional recovery rate, ensuring optimal performance and efficiency, enhancing overall functionality.
4. One significant drawback of the purifier is the absence of a flushing function, which leads to the accumulation of high-concentration brine over time within the RO membrane shell, potentially impacting its longevity and effectiveness.
