[求助] 请牛人用地道句子改一下?

我写的如下,但句子太长。However, which limits the practical use of titanium dioxide photocatalyst is that, after using it to treat the wasterwater, not only the photocatalys has to be filtered in order not to affect the quality of effluent, but also the photocatalys must be reused to save the expense.

However, the practical use of TiO2 photocatalyst into wasterwater treatment is limited in two ways: it has to be filtered so as not to reduce the quality of the effluent, and it must be reused so as to save the expense.

However,in the practical process of wastewater treatment using titanium dioxide photocatalyst, the reason for the limited efficacy of the titanium dioxide photocatalyst was that the titanium dioxide photocatalyst was over-reused for saving the expense as well as being filtered to guarantee the quality of effluent.
