A review of physical–biochemical clogging in granular filters for groundwater treatment
Environmental GeotechnicsGranular filters play critical role in controlling soil erosion, enhancing drainage efficiency, and improving water quality in groundwater treatment facilities. However, clogging of filters can significantly degrade their performance, leading to their increased maintenance and reduced lifespan.

Transport in Porous Media, 2014
The effects of the hydraulic operating conditions and the concentration of suspended particles (SP) in pore fluid on the filtration and physical clogging of a porous medium were investigated. Polydisperse kaolinite SP was injected into a sand-filled column under two different operating conditions: constant flow rate and constant head.

Physical Clogging of Uniformly Graded Porous Media Under Constant Flow rates
Transport in Porous Media, 2017This study investigated the physical clogging of uniformly graded porous media under constant flow rates using natural porous media and suspensions. The porous media selected for this experimental study was a fine-to-medium sandy soil fractioned into thirteen uniformly graded beds: seven unisize beds and six uniform beds.

AbstractIn this study, a gradient ratio test which is one of the methods used in the laboratory to evaluate the clogging potential of soil‐synthetic envelope systems was applied. For this purpose, two physical models of permeameters (designed by ASTM D‐5101) were used to carry out a series of permeability tests by applying water with different ...

Abstract A major drawback limiting the use of trickle-bed bioreactors for biological wastewater treatment is ascribed to the concomitant biological clogging and physical plugging phenomena induced, respectively, by the formation of an excessive amount of biomass and the retention of inert suspended fine particles advected in the liquid influent ...

Physical clogging of soil filters under constant flow rate versus constant head
Canadian Geotechnical Journal, 2005In this study, the differences in soil filter clogging are evaluated under two operating conditions: constant head and constant flow rate. Whereas filters placed around well screens and leachate collection systems are subjected to a constant flow rate, filters in earth dams and pavement drainage systems operate under constant or slightly varying heads.

Abstract In this study, we have investigated the chemical and physical effects on the mechanism of sump screen clogging of containment materials that are used in most Korean nuclear power plants, such as N-102, N-108 as coating materials, NUKON as insulating materials, and CLP and SSLP as pipe materials.

The water table apparatus allows the qualitative visualization of natural ventilation in reduced physical models. The quality of the results depends on several parameters, such as the obstruction rate of the reduced physical model in the test area. However, there is a lack of scientific research that analyzes the influence of this rate on the quality ...
