  • Role of biological activity and biomass distribution in ...

    The amount of biomass can reflect the biofilter performance that is relevant to microbial activity (Devinny et al., 1996). Active microorganisms could be found in the biofilter where biomass accumulates rapidly. Excess accumulation of biomass causes severe biofilter operating problems including an increase in airflow resistance within the bed and low contaminant removal efficiencies

  • Simulation of Biomass Accumulation Pattern in Vapor

    Abstract Existence of inert biomass and its impact on biomass accumulation patterns and biofilter performance were investigated. Four biofilters were set up in parallel to treat gaseous toluene. Each biofilter operated under different inlet toluene loadings for 100 days. Two microbial growth models, one with an inert biomass assumption and the other without, were established and compared.

    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

  • Biofilter - Wikipedia

    Oxygen can be supplied to the biofilm, either concurrently or countercurrently with water flow. Aeration occurs passively by the natural flow of air through the process (three phase biofilter) or by forced air supplied by blowers. Microorganisms' activity is a key-factor of the process performance. The main influencing factors are the water ...

    Microbial activity was highest under oxic conditions and abruptly decreased under anoxic conditions. Activity peaks were observed after about 9 d of anoxic conditions probably triggered by increased nutrient availability from dying microbial biomass, but these peaks were smaller after initial oxic incubation or nitrate addition.

    Particulates were more responsible for ultrafiltration membrane fouling in the stationary phase of microbial growth, but soluble materials were more accountable in the death phase of microbial growth. Statistical analysis indicated biomass with lower activity could experience higher fouling potential during ultrafiltration of biomass.
