Biomass and microbial activity in a biofilter …

Assuming the biomass and microbial activity along the biofilter depth at different air velocity are m 7 (x), m 9 (x), m 11 (x), m 13 (x) and n 7 (x), n 9 (x), n 11 (x), n 13 (x) respectively, according to Eq., the average oxygen demand of the whole biofilter can be decided not only during running operation but also after backwashing.

Biomass and microbial activity in a biofilter …

The microbial groups revealed new distribution along the biofilter depth after low flow rate backwashing for a short time. Then the start-up process was accelerated by backwashing. The biomass profile and microbial activity profile both varying with depth before and after backwashing, can be mathematically described by quadratic equations.

Role of biological activity and biomass …

A few studies reported the effect of starvation on biological activity and biomass variation in gas phase bioreactors (Martin and Loehr, 1996, Metris et al., 2001, Cox and Deshusses, 2002). Cox and Deshusses (2002) observed that 10–50% of biomass in the biofilter was lost during 7 d of starvation.

Microbial activity and biomass in saline soils as affected ...

Microbial activity and biomass in saline soils have been extensively studied, but a little is known about the effect of organic carbon (OC) addition on adaptation of soil microbes to salinity. The objective of this thesis was to determine the effect of OC availability on adaptation of soil microbial activity and biomass to salinity.

Simulation of Biomass Accumulation Pattern in …

In the microbial model, when inert biomass is considered, the calculated biomass accumulation pattern shows agreement with the experimental data for all four biofilters in Phase I and Phase II (Fig. 2). This result verifies that the microbial growth model with an inert biomass assumption successfully describes the real biomass accumulation process.
