WebApr 11, 2024 · The basis to determine biofilm thickness was z‐images of a 185 µm wide area taken on ten randomly chosen sections on the biofilm. For optimum analysis laser intensity should be chosen in a way that the biofilm is clearly distinguished but not overexposed. The Syto9 fluorescence signal was subsequently used as input for … WebOct 29, 2024 · This structural heterogeneity is evident on even smaller, μm-scale, where variations of up to 74% in biofilm thickness could be identified ( Figure 4 ). Consistent to the control hose, thickness data was used to calculate the approximate average biofilm volume, which was 9.8 ± 4.6 × 10 8 μm 3 /cm 2 ( n = 200).
WebWe used novel carriers (Z-carriers, AnoxKaldnes) that allowed controlling biofilm thickness at 50, 200, 300, 400, and 500 μm. The impact of biofilm thickness on microbial … WebJan 10, 2024 · Biofilm thickness generally ranged between 170 and 240 μm, with internal biofilm porosities estimated as 34 ± 10 %, reaching a maximum of 50 %. Internal biofilm matrix pore diameters ranged from 1 to 205.2 μm, with a distribution that favored pores and channels smaller than 10 μm, and a mean equivalent spherical diameter of 8.6 μm.
WebDiatomaceous biofilms can increase vessel hull friction by up to 70% based on the biofilm's thickness and percentage coverage; this can require increases in vessel power between 1.5 and 10.1% ... WebTwo new emerging “thickness-restraint” carriers, AnoxK™ Z-200 and Z-400 (allowing for 200 and 400 μm maximum biofilm thickness, respectively), are compared to the conventional AnoxK™ K5 carrier at BOD loading rates of 6 g-sBOD m −2 d −1. The obtained results indicate that carrier type has a significant effect on MBBR carbonaceous ...
WebMar 1, 1995 · A convenient physical model for biomass involves consideration of individual cells as “active” centers dispersed through a continuous region in which transport takes place by molecular diffusion.
