The buffer and active layers allow for the easy  formation of the active layer on the support and selective permeation of the ceramic membrane, respectively. The  average pore sizes of the support, buffer layer, and active layer were 2,677, 773.3, and 33.1 nm, respectively. The  diameters of the active layer pores were <0.1 μm. The ceramic membrane performance and mechanical scraping effects  on the membrane permeability improvement were evaluated. Mixed liquor suspended solids (MLSS) were used for the  feed of an enhanced ceramic membrane filtration system, by combining the fabricated membranes and devised scrapers.  The average flux recovery by scraping was 54% of the clean water flux; maintained by scraping despite the high turbidity  feed. The permeation concluded within 0.2 h during scrape-off. This was not recovered despite scraping because the  internal membrane pores became blocked due to the material turbidity and could not be separated at the surface of the  ceramic membrane.  %U https://www.msrjournal.com/article_246030_0a7d79663a5f4a08cb79074c89aba583.pdf
