  • 1. Product Performance

    EQ‑506 reverse osmosis membrane cleaning agent is a high‑pH solid‑formula alkaline RO membrane cleaner, mainly used to remove organic substances, colloids, microorganisms and particulate matter. It is applicable to aromatic polyamide reverse osmosis membranes, hollow‑fiber membranes, nanofiltration (NF) and ultrafiltration (UF) membranes. Its excellent cleaning performance can extend the operating time of membranes.

    1. This alkaline RO cleaning agent is suitable for all aromatic polyamide membranes.
    2. It can remove oil and organic substances from membrane surfaces.
    3. It delivers good performance in removing biological slime on membrane surfaces.
    4. Better cleaning effect can be obtained when this product is used together with EQ‑501 acidic membrane cleaning agent.
    5. Adjust pH of diluted solution to 11‑12.
    6. Elevated temperature brings better cleaning effect and shortens mixing time.

    2. Technical Specifications

    ItemSpecification
    AppearanceWhite powder
    pH (1% solution)11.0‑12.0
    Minimum Storage Temperature≥‑15℃

    3. Dosing Instructions

    Calculate the proper dosing concentration according to water quality analysis report and system conditions. Normally, the reverse osmosis membrane cleaning agent is dosed into the chemical tank at a typical concentration of 1‑3 %.

    4. Cleaning Instructions

    ▲ Inspect and flush the whole RO cleaning system to keep it clean. 

    ▲ Before cleaning, identify the contamination type and root cause of RO membrane elements to achieve targeted cleaning. 

    ▲ After cleaning, analyze the causes of contamination and implement corresponding pre‑treatment preventive measures. 

    ▲ During cleaning, keep the temperature of cleaning solution within the required range of 25‑35 ℃ at all times. 

    ▲ Follow the flow rate recommended by membrane manufacturer or reverse osmosis cleaning agent supplier. Besides, flow rate and soaking time shall be determined according to contamination type and severity of membrane elements. If no recommended value is available, technical engineers from JQSY can provide guidance based on actual system conditions. 

    ▲ For heavily contaminated systems, consult technical engineers from JQSY for an optimized cleaning procedure. 

    ▲ For multi‑stage RO systems, clean each stage separately for better results. If the cleaning solution turns turbid or pH goes beyond the recommended range, re‑prepare the solution or replenish alkaline membrane cleaning agent. Thoroughly rinse the system with RO product water before putting it back into service.

    5. Packaging & Storage

    1. Packed in plastic drums, 20 kg or 25 kg per drum.
    2. Stable physical‑chemical properties. Store in cool place. Shelf‑life: 12 months.

    6. Safety & Protection

    When using EQ‑506 Reverse Osmosis Membrane Cleaning Agent (Alkaline Solid), wear protective goggles and gloves. In case of splashing onto skin, rinse with clean water.
