Application of biochar in modification of fillers in bioretention cells: A review

Biofilters and bioretention systems: the role of biochar in the blue-green city concept for stormwater management

“…The biochars' bacterial capacity depends on the properties of biochar, the surface characteristics of bacteria, and the composition of runoff. 134 An enhancement of E. coli removal was shown by biochar-amended columns compared to sand-only columns. [135][136][137] The high surface area of biochar facilitates the adsorption of E. coli by increasing overall attractive forces between the biochar surface and the bacteria surface.…”

“…The environmental factors such as temperature fluctuations, dry-wet climate cycles, and freeze-thaw cycles also influence the potential of biochar to remove biological contaminants from stormwater. 134 At high temperature, interactions between biochar and bacteria are low because oxidation has increased the surface negative charge of biochar. 139 Furthermore, biochar's physical weathering has increased the biochar's bacterial removal capacity by altering the surface characteristics.…”

Effect on the adsorption performance and mechanism of antibiotics tetracyclines by the magnetic biochar used peanut shells as raw materials

“…The conical bottles were placed in a magnetic stirrer with a rotation speed of 150 rpm for adsorption experiments. After the reaction, the mixture was separated by magnet, and the effect of Fe 3 O 4 /BC dosage on the performance of the TC solution was obtained [41].The filtrate was filtered through a 0.45 μm membrane. The maximum absorption wavelength of TC was 356nm, and the absorbance of filtrate was measured by UV-visible spectrophotometer.…”
