Q: Is a single 1*400GPD system more effective than a dual 2*200GPD setup?
A: Choosing the 200GPD system offers benefits such as reduced adhesive use during production, leading to enhanced salt rejection rates and improved water flow efficiency.
Q: When is it necessary to clean membrane elements?
A: It is essential to clean membrane elements when you notice any of the following signs:
A significant reduction of 10-15% in normalized permeate flow indicates the need for cleaning.
An increase of 10-15% in the normalized permeate total dissolved solids (TDS) is a clear signal for cleaning.
A rise of 10-15% in the normalized pressure drop between the feed and reject streams necessitates cleaning.
Q: How can you resolve RO membrane blockage effectively?
A: 1. First, confirm if the home RO System's membrane is genuinely blocked.
2. Evaluate the regional water quality, especially if calcium and magnesium salts are the main scaling components.
3. Prepare a solution using 10% hydrochloric acid or a diluted market-available descaling detergent, along with a specialized RO membrane cleaning agent, based on the scale composition. Immerse the RO membrane for 24 hours for optimal results.
4. After soaking, rinse the RO membrane with ultrafiltration-produced water. 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 raw water leads to excessive scaling, which can cause blockages.
2. When organic matter in water exceeds safe thresholds, it results in the fouling and blockage of the RO membrane, compromising its efficacy.
3. Our advanced RO film technology ensures an exceptional recovery rate, optimizing water purification performance.
4. Without a flushing function, the purifier allows for the accumulation of high-concentration brine within the RO membrane shell over time, potentially hindering its efficiency.
