RO membrane’s surface that accumulated biofilm(biofouling) is removed bydisinfectant(biocide). Usually biocide for RO’s biofouling removal uses oxidizing biocide(NaOCl) andnon-oxidizing biocide. At the condition that have a high concentration of biofilms was more removedby only using the non-oxidizing biocide on the RO membrane surface than using both oxidizing andnon-oxidizing biocide. Also the single use of non-oxidizing biocide enhanced operating time of ROmembrane and that reducing differential pressure’s rising and minimizing the operating cost by thestop using RO’s Chemicals ; NaOCl and NaHSO |
