Q: Is a single 1*400GPD system superior to a dual 2*200GPD setup?
A: Opting for the 200GPD system offers several advantages, including minimized adhesive usage during manufacturing, significantly enhancing salt rejection rates and facilitating superior water flow efficiency.
Q: When should membrane elements undergo cleaning?
A: It is crucial to clean the membrane elements under the following conditions:
When experiencing a noticeable reduction of 10-15% in normalized permeate flow, it's time for cleaning.
A marked 10-15% increase in normalized permeate total dissolved solids (TDS) indicates a need for cleaning.
A significant 10-15% rise in 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. Verify if the membrane in your home RO system is blocked.
2. Examine 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 descaler, combined with an RO membrane cleaning agent, based on scale composition. Soak for 24 hours.
4. After soaking, thoroughly rinse the RO membrane using ultrafiltration water. 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 raw water leads to excessive scaling, causing blockages.
2. Elevated levels of organic matter exceed standards, resulting in RO membrane fouling and subsequent blockage.
3. Introducing a truly remarkable RO film that redefines excellence with its exceptional recovery rate, ensuring optimal performance and unparalleled efficiency. Experience a breakthrough in water purification technology that consistently delivers superior results.
4. A notable consideration for this purifier is the lack of a flushing function. This can result in the accumulation of high-concentration brine within the RO membrane shell over time, potentially affecting its longevity and overall effectiveness. It's an aspect to keep in mind when evaluating the long-term maintenance and performance of the system.
