Q: Is a single 1*400GPD system superior to two 2*200GPD systems?
A: Opt for the 200GPD system. It minimizes adhesive usage during production, improves salt rejection rates, and enhances water flow, making it the superior choice.
Q: When should the membrane elements be cleaned to maintain optimal performance?
A: Cleaning is essential when observing any of these conditions:
A decrease of 10-15% in normalized permeate flow.
An increase of 10-15% in normalized permeate total dissolved solids (TDS).
An increase of 10-15% in normalized pressure drop between feed and reject.
Q: What are the steps to resolve RO Membrane Blockage effectively?
A: 1. Initially, verify if the home RO System membrane is genuinely blocked.
2. Evaluate regional water quality to identify if calcium and magnesium salts are the primary scale components.
3. Prepare a solution with 10% hydrochloric acid or a diluted detergent (choose from available descaling agents), along with a specialized RO membrane cleaning agent based on the scale composition. Immerse the RO membrane in this solution for 24 hours.
4. After soaking, thoroughly rinse the RO membrane. Use water produced by ultrafiltration for this process. During rinsing, close the pure water outlet and open only the wastewater outlet.
Q: Why does the RO membrane experience blockage within one to two months?
A: 1. Elevated salt content in raw water can lead to excessive scale formation.
2. Excessive organic matter in water might surpass safe levels, causing fouling and clogging of the RO membrane.
3. A high recovery rate of the RO film may contribute to blockage.
4. Absence of a flushing function in the purifier can lead to high-concentration brine deposits within the RO membrane shell over time.
