Bioretention for stormwater quality improvement in Texas: Removal effectiveness of Escherichia coli
This study investigated the removal effectiveness of Escherichia coli by five pilot bioretention units with different vegetations. The bioretention units were originally planted or seeded with one of the following vegetation: shrubs, grass species specified for Texas highway applications, Texas native grasses, Bermudagrass (Cynodon dactylon), and none (control unit). To mimic highway conditions...
متن کاملEscherichia coli Removal in Biochar-Modified Biofilters: Effects of Biofilm
The presence of microbial contaminants in urban stormwater is a significant concern for public health; however, their removal by traditional stormwater biofilters has been reported as inconsistent and inadequate. Recent work has explored the use of biochar to improve performance of stormwater biofilters under simplified conditions that do not consider potential effects of biofilm development on...
متن کاملEngineered bioretention for removal of nitrate from stormwater runoff.
A bioretention unit is a simple, plant- and soil-based, low-impact treatment and infiltration facility for treating stormwater runoff in developed areas. Nitrate, however, is not attenuated in conventional bioretention facilities. Thus, this study systematically evaluated a reengineered concept of bioretention for nitrate removal via microbial denitrification, which incorporates a continuously ...
متن کاملBioretention column studies of phosphorus removal from urban stormwater runoff.
This study investigated the effectiveness of bioretention as a stormwater management practice using repetitive bioretention columns for phosphorus removal. Bioretention media, with a higher short-term phosphorus sorption capacity, retained more phosphorus from infiltrating runoff after 3 mg/L phosphorus loading. A surface mulch layer prevented clogging after repetitive total suspended solids in...
متن کاملNitrogen removal from urban stormwater runoff through layered bioretention columns.
Bioretention is a low-impact technology used for the treatment of stormwater runoff in developed areas. The fates of mineral nitrogen compounds in two bioretention columns (RP1 and RP2) with different media-layering characteristics were investigated under multiple loadings of simulated urban runoff. The immediate capture of nitrogen was evaluated, with nitrogen transformation reactions that occ...
