Reverse Osmosis Membrane Acid Cleaner (Liquid Acidic) EQ-501

Reverse Osmosis Membrane Acid Cleaner (Liquid Acid)EQ-501

EQ-501 is a low pH liquid formulation designed to remove metal hydroxides, calcium carbonate, and other salt scale deposits. It is suitable for aromatic polyamide reverse osmosis membranes, hollow fiber membranes, as well as nanofiltration (NF) and ultrafiltration (UF) systems, and can extend membrane operating time.

III. Dosing Instructions

Based on water quality analysis reports and system conditions, calculate an appropriate dosing concentration. Typically, the product is dosed into the cleaning tank at a concentration of 2–4%.

IV. Cleaning Instructions

▲ Before cleaning, it is essential to clearly identify the type of fouling in the RO membrane elements and the cause of such fouling to ensure targeted treatment;

▲ After cleaning, analyze the cause of fouling and implement corresponding pretreatment preventive measures;

▲ During the cleaning process, maintain the temperature of the cleaning solution within the required range (25–35℃);

▲ The cleaning flow rate should follow the recommendations of the membrane manufacturer or chemical supplier. Additionally, the flow rate and soaking duration should be determined based on the type and severity of membrane fouling (if no recommendation is available, our technical engineers can provide guidance based on the actual system conditions);

▲ For multi-stage RO systems, it is best to clean each stage separately for optimal results. If the cleaning solution becomes turbid or the pH exceeds the recommended range, prepare a new cleaning solution or replenish the cleaner. Before putting the system back into operation, rinse it thoroughly with RO product water.
