Method for identification of clogging
Can be well controlled and easily executed in the laboratory (Siegrist 1987; Ganot et al. 2017).
The low cohesive medium prevents the withdrawal of undisturbed samples (Siegrist 1987; Matos et al. 2019).
No comparability between different configurations and operation conditions (Ganot et al. 2017; Sobotkova et al. 2018).
Reveals the water flow conditions and is suitable for different configurations (Hübner et al. 2013).
The complete decay time and its toxicity on microorganisms are yet to be revealed (Lancheros et al. 2017; Matos et al. 2019; Li et al. 2020).
The influencing factors considered are continuously improved (Samsó & García 2014; Coulon et al. 2015; Pei et al. 2018).
Few have been successfully applied in large-scale clogging predictions (Ganot et al. 2017; Pucher & Langergraber 2019).
The accuracy is restricted by complex factors (Coulon et al. 2015).
Measurement of electrical resistivity
Easy to operate in the laboratory and online (Liu et al. 2018a, 2018b).
Requires sophisticated equipment and has less indications for obstruction caused by organic compounds (Zhao et al. 2009).
