Xiao JianPing. Organic Fouling and Cleaning of UF Membrane[J]. Journal of Civil and Environmental Engineering, 2005, 27(4): 74-76. DOI: 10.11835/j.issn.1674-4764.2005.04.017.
the problem of fouling on UF membrane mainly centers on the aspect of organic fouling. The cleaning methods of jam caused by fouling of polysulfone UF membrane
the behavior of organic fouling and the elimination of contamination are studied using several chemicals. This experiment proves that NaClO
H2O2 and NaOH all have some effect on the removing organic fouling of UF membrane
of which the H2O2 has the best effect. Controlling the pH value of raw water can decrease the organic fouling of UF membrane. At the same time
a very good result can be gained in the elimination of organic fouling in a way of combining the water solution of NaOH/NaClO and NaOH/H2O2
which makes the infiltration water flux of UF membrane being restored to its initial value. Moreover
the mechanism of organic fouling formation of UF membrane is analyzed.
