| Abstract: | The cleaning process of ceramic microfiltration membranes used in recovering TiO 2 particle from wastewater was studied.The effect of several cleaning agents and the influence of cleaning time,back-pulse et al. on the cleaning results were investigated.The repetition of cleaning was also tested.The cleaning mechanism was analyzed with the results of SEM micrograph and EDX.All these work are benefit for industrialization of this process. |
