Q: Is a single 1*400GPD system superior to a dual 2*200GPD setup?
A: Choosing a 200GPD system offers numerous benefits, including reduced adhesive use during manufacturing, which enhances salt rejection rates and supports superior water flow efficiency.
Q: When should membrane elements undergo cleaning?
A: It is crucial to clean the membrane elements under the following circumstances:
When you observe a significant 10-15% reduction in normalized permeate flow, it's an indication that cleaning is necessary.
A substantial 10-15% increase in normalized permeate total dissolved solids (TDS) signals the need for cleaning.
A noticeable 10-15% rise in the normalized pressure drop between the feed and reject streams indicates that cleaning is required.
Q: What are the steps to resolve RO membrane blockage?
A: 1. Begin by checking if the membrane in your home RO system is indeed blocked.
2. Assess the local water quality, particularly noting if calcium and magnesium salts are the main scaling contributors.
3. Prepare a cleaning solution using 10% hydrochloric acid or a commercially available descaling detergent with a specialized RO membrane cleaning agent, tailored to 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?
A: 1. High salt content in the raw water results in excessive scaling, leading to blockages.
2. Elevated levels of organic matter in the water surpass acceptable standards. This leads to the fouling and subsequent blockage of the RO membrane, hindering the system's efficiency.
3. This extraordinary RO film features an outstanding recovery rate, ensuring peak performance and unmatched efficiency for your water purification needs.
4. A notable drawback of the purifier is the lack of a flushing function. This absence results in the gradual accumulation of high-concentration brine within the RO membrane shell, which may impact its longevity and overall effectiveness.
