Average mass transfer coefficients of an inert compound (LiCI) within denitrifying biofilms were monitored during biofilm growth in a membrane flow cell under different flow conditions, until the biofilm reached (pseudo-) steady state. Average effective diffusivities were found to increase with the decrease tortuosity factors of the biofilm matrix. The lowest tortuosity factor corresponded the highest liquid velocity.
在膜流动池中不同流动条件下生物膜生长过程中，对反硝化生物膜内惰性化合物（LiCI）的平均传质系数进行了监测，直至生物膜达到（准）稳态。发现平均有效扩散率随着生物膜基质曲折因子的降低而增加。最低的曲折因子对应最高的液体流速。
