The understanding of development of clogging in the SWI beds

StagePeriodRepresentative views and references
1960–1980 
  • As long as the influent load is well controlled, nitrogen and phosphorus can be fully utilized through soil respiration (Lan et al. 2015).

  • The physio-chemical properties of the soil will not be significantly affected (Garcia-Fernandez et al. 2016).

  • The system can operate stably for a long time (Meireles et al. 2016).

 
II 1980–2000 
  • The porous characteristics and vertical structure of the infiltration bed are the keys to maintain the flow condition (Siegrist 1987; Ye et al. 2015; Hua et al. 2017).

  • Clogging of porous media is mainly resulted from the suspended solids and high hydraulic loads (Panán et al. 2016; Ye et al. 2018).

 
III 2000–2010 
  • The micro-environmental zoning in the matrix creates different types of microbial populations and restricts them to maintain metabolic and physiological activity within a given layer (Ding et al. 2018).

  • The sewage is infiltrated driven by capillary force and gravity (Dua et al. 2018).

  • Biofilm growth and extracellular polymer aggregation are the main features of biological clogging (Xia et al. 2020).

 
IV 2010 to present 
  • Clogging may have multiple inducing factors other than the physical and biological clogging (Coulon et al. 2015; Reid et al. 2015).

  • The adaptability of the system is quantitatively related to the operation conditions (Wu et al. 2015; Li et al. 2018).

  • Without clogging, SWI is a good natural bio-reactor (Perujo et al. 2018; Zhou et al. 2018).
