Q: Is a single 1*400GPD system superior to two 2*200GPD systems?
A: Opt for the 200GPD system for better performance. It reduces adhesive use during production, improves salt rejection rates, and enhances overall water flow.
Q: When should the membrane elements be cleaned to maintain optimal performance?
A: Cleaning is necessary when the following conditions are observed:
A noticeable decrease of 10-15% in normalized permeate flow signals the need for cleaning.
An increase of 10-15% in normalized permeate TDS indicates it's time for maintenance.
A rise of 10-15% in normalized pressure drop between feed and reject necessitates cleaning.
Q: What are the steps to resolve RO Membrane Blockage effectively?
A: 1. First, confirm if the home RO System membrane is truly blocked to ensure accurate diagnosis.
2. Evaluate the regional water quality to identify if calcium and magnesium salts are the main scale components.
3. Prepare a cleaning solution with 10% hydrochloric acid or diluted detergent, along with a specialized RO membrane cleaning agent. Immerse the RO membrane for 24 hours to dissolve scale.
4. Rinse the RO membrane thoroughly post-soaking. Use ultrafiltration-produced water, keeping the pure water outlet closed and only the wastewater outlet open during this process.
Q: Why does the RO membrane experience blockage within one to two months?
A: 1. High salt content in raw water may cause excessive scaling, leading to blockage.
2. Excessive organic matter in the water can foul the RO membrane, resulting in clogs.
3. A high RO film recovery rate may contribute to blockage, requiring regular maintenance.
4. Absence of a flushing function in the purifier can cause high-concentration brine deposits, leading to membrane blockage over time.
