Reverse Osmosis membrane acidic cleaner (liquid acidic) EQ-501

1, Property and Uses
EQ-501 is a low-pH liquid formulation designed to remove scaling from metal hydroxides, calcium carbonate, and other salts, and is suitable for aromatic polyacyls
Amine reverse osmosis membranes, hollow fiber membranes, as well as sodium filtration (NF) and ultrafiltration (UF), can extend membrane operating time.

3. Add-on Instructions
Based on the water quality analysis report and system conditions, calculate an appropriate dosing concentration. Usually, the agent is added to the cleaning tank at a concentration of 2~4%.
4. Cleaning instructions
▲ Before cleaning, it is essential to basically clarify the type of contamination in the RO membrane element and the cause of the contamination, and to address the issue accordingly;
▲ After cleaning, analyze the causes of contamination and implement corresponding pretreatment and defense measures;
▲ During cleaning, the temperature of the cleaning solution must always be kept within the required range (25~35°C);
▲ The cleaning flow rate should be based on the recommended value of the membrane manufacturer or chemical supplier. Additionally, the flow rate and the soaking time should be determined based on the type and degree of contamination of the membrane element (if this value is not 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 maximum effectiveness. If the wash solution becomes cloudy or the pH exceeds the recommended range, it must be reformulated
For washing liquids or supplementing cleaning agents, the system must be flushed with RO-produced water before reactivation.
