Alkaline cleaning agent is a specialized chemical used in reverse osmosis (RO) membrane systems, mainly for removing oil stains, organic matter, and biological mucosa. Here are some detailed information about alkaline cleaning agent KR-261:

1. Scope of application: KR-261 alkaline cleaning agent is suitable for all aromatic polyamide and cellulose acetate membranes.
2. Active ingredients: It can effectively remove oil stains, organic matter, and biological mucosa on the membrane surface.
3. Temperature effect: As the temperature increases, the cleaning effect will be better.
4. pH value: After dilution, the pH value is maintained at 10.5 ± 0.5.
5. Dilution ratio: It is recommended to dilute the ratio to 1-3% (1:45).
6. Appearance: Colorless to light yellow transparent liquid.
7. Density: At 20 ℃, the density should be at least 1.05 g/cm ³.
8. Storage conditions: The storage temperature should not be lower than -5 ℃.
9. Safety and protection: Avoid contact with eyes and skin. Once in contact, rinse immediately with plenty of water.
   The usage method includes checking the water tank, pipeline, and filter, and replacing the filter material if necessary; Input RO produced water into the water tank; Input KR-261 into the water tank, mix the solution with a water pump, and measure the pH value; Clean the system repeatedly according to the degree of pollution, and be careful not to exceed the required temperature of the solution.
   In addition, there is also an IR-261 acid-base cleaning agent, which is a liquid alkaline formula suitable for removing oil stains, organic matter, and biological mucosa, with similar performance and usage methods.
   When selecting a suitable alkaline cleaning agent, the type and degree of fouling of the membrane should be considered to ensure cleaning effectiveness and extend the service life of the RO membrane.
