LH-881 Acidic reverse osmosis detergent
◇Product character:
1. It is applicable to all aromatic polyamide membrane and acetic acid membrane.
2. It is low bubble recipe.
3. The PH value of dilutions must maintain in 3 + 0.5.
4. It can be used as detergent in production of drinking water in reverse osmosis system.
5. Temperature can be enhanced to strengthen the effect.

◇Product description and purposes
The product is a lower pH acidic formula. It is suitable for aromatic polyamide reverse osmosis membrane, hollow fiber membrane and nanofiltration (NF) and ultrafiltration (UF) membranes. It is used to remove metal hydroxides, calcium carbonate and other kind of fouling, Excellent cleaning effect can extend the membrane running time. In order to get the best results, LH - 881 should be used together with LH - 81.
◇Dosing and the application requirements
Dosing system- The product should be used in combination with membrane cleaning equipment produced by membrane system manufacturers.
Dilution- The dilution of the product must be carried out before entering membrane system. Usually the dilution proportion is 1-3% of the whole cleaning system volume (Usually 1:45). The whole system includes wash tank, connecting pipe, filters, pressure vessel and membrane.
Material compatibility- This corrosion resistant material of the product for storage or allocate equipment application, like PVC. The parts that are contacted with pump and concentrate or dilution product should be used materials with resistance to corrosion.
◇Cleaning explaining:
1. Check wash tank, hose and the security filter.
2. Infuse the reverse osmosis water or the dematerialized water into the wash tank. Infuse slowly the calculated dosage into the wash tank, cycle mixed solution with a clean pump, heat the mixed solution By a heater to the highest temperature that film makers stipulated.
3. Do the circulation cleaning at the direction of the coming water for 30 minutes. The cleaning flow should be according to the recommended values from the membrane manufacturer or system supplier.
4. If pollution is serious, you should send the initial back fluid (Volume is about 15% of wash tank) out to prevent contaminants attaching on the membrane surface again.
5. For the first paragraph system, each paragraph should be cleaned alone for the maximum alone effect, If the cleanout fluid gets turbid or pH value increases beyond recommended value range, therefore in other segment cleaning fluid should be cleaned out and reconfigure the cleaning fluid.
6. It will be best to rinse through water with reverse osmosis before the system start again.
◇Packing
Product packaging is 20kg-25 kg/plastic bucket
