Abstract
In order to safeguard the water security and resilience for sustainable development, there is an imminent need to develop blue-green infrastructures to cater to the environmentally friendly drainage networks. This chapter will introduce the application of a bioretention system (e.g., bioswale and biofiltration basin) as a simple and passive measure for stormwater harvesting at the source for non-potable reuse. In view of the insufficient contaminants removal in typical bioretention systems, development of engineered filter media mixed with biochar is encouraged to improve the harvested stormwater quality to meet the local/international standards and provide additional removal capacity. Recent advances in biochar-assisted removal of organic/inorganic contaminants, including biochar modification, process design, aging effects, etc., will be summarized and discussed. In addition, this chapter provides suggestions for flow attenuation, design, and maintenance requirements, which are important considerations in the establishment of sustainable and environmentally compatible pilot-/field-scale bioretention systems.
