Effect of liquid distribution on the organic removal in a trickle bed filter

Analysis of the rate-limiting step of an anaerobic biotrickling filter removing TCE vapors

“…This is only because gas and water flowed co-currently, resulting in bubbling regime rather than complete flooding [26]. Nonetheless, pollutant elimination can be a direct function of the liquid distribution [27], and thus under bubbling regime, channeling of liquid and thus irregular distribution, most likely affected the TCE EC.…”

Nitrogen utilization and biomass yield in trickle bed air biofilters

“…Trickle bed air biofilter (TBAB) facilitates more consistent operation than traditional biofilter due to better control of overall pressure drop, nutrient concentration, and pH [2][3][4], but it is conceptually a similar process.…”

Performance Evaluation of Trickling Filter-Based Wastewater Treatment System Utilizing Cotton Sticks as Filter Media

“…Many researchers explained that color in WW occurs due to the presence of dissolved minerals, organics, and chemicals. Reduction in color occurred due to adsorption capability of filter media [25,33,48].…”

“…Most of the studies investigated that with increasing loading rates system efficiency decreases. This occurred due to the varying loadings in the influent can cause an increase in average effluent concentration because of the decrease in retention time of WW to contact with slime layer to oxidize the organic matters as well as the non-uniform development of biofilm in the internal structure [33,42,[46][47][48][49].…”

“…Many of the other studies concluded that dissolved solids, suspended solids, and COD are related to electrical conductivity levels in WW. The higher value of solids shows more EC [25,[48][49][50][51][52].…”
