Alkaline Membrane Cleaner (Solid)

Alkaline Membrane Cleaner (Solid)

I. Performance and Applications
It is a high-pH liquid formulation primarily used to remove organic matter, colloids, microorganisms, and particulate substances. It is suitable for aromatic polyamide reverse osmosis membranes, hollow fiber membranes, as well as nanofiltration (NF) and ultrafiltration (UF) membranes. Excellent cleaning performance extends membrane operation time.
▲ Suitable for all aromatic polyamide membranes;
▲ Optimal results when used in combination with acidic membrane cleaners;
▲ Efficiently removes oil and organic matter from membrane surfaces;
▲ Effective in eliminating biological slime on membrane surfaces;
▲ Diluted solution maintains pH between 11 and 12;
▲ Liquid agent reduces mixing time; higher temperatures enhance effectiveness.

III. Dosing Instructions
Typically, the concentration of this agent in the chemical tank is 1–3%.
IV. Cleaning Instructions
▲ Inspect and flush the entire RO cleaning system to ensure cleanliness;
▲ Before cleaning, identify the type of contamination affecting the RO membrane elements and the cause to apply targeted treatment;
▲ After cleaning, analyze the cause of contamination and implement appropriate pretreatment preventive measures;
▲ Maintain cleaning solution temperature within the recommended range (25–35°C) throughout the cleaning process;
▲ Use flow rates recommended by the membrane manufacturer or chemical supplier; adjust flow rate and soaking time based on the type and severity of membrane contamination (consult a technical engineer if no recommendation is available);
▲ For severely contaminated systems, consult a technical engineer for an optimized cleaning plan;
▲ For multi-stage RO systems, clean each stage separately for better results. If the cleaning solution becomes cloudy or the pH exceeds the recommended range, prepare a new solution or replenish the cleaner. Rinse with RO product water before putting the system back into operation.
V. Packaging and Storage
