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.

Agricultural Water Management, 2022
High-sediment water in drip irrigation (HSWDI) technology offers the opportunity to alleviate water shortages in agricultural irrigation. Emitter clogging, caused by active suspended particles, salt ions, and microorganisms present in water with high sediment load, poses considerable technical challenges to HSWDI.

Background: The World Health Organization supports and recognizes the benefits of breastfeeding, at least 6 months or more, for both a mother and her baby. A common cause for cessation of breastfeeding is the development of mastitis typically caused by a clogged milk duct.

Understanding physical clogging in drip irrigation: in situ, in-lab and numerical approaches
Irrigation Science, 2016Dripper clogging is a major drawback of microirrigation systems that must be addressed to improve their efficiency and durability. Particle-induced clogging is first studied in situ. The experiments consist in observing in real conditions the behavior of a series of drippers fitted on an agricultural plot in the south of France.

Physical Modeling on the Mold Flow Field Influenced by Nozzle Clogging
2013Based on a real slab caster mold as prototype, a plexiglass model with 1:1 scale was established to investigate the influence of nozzle clogging on the mold flow field. The flow field was displayed by injecting black ink through SEN and the effects of casting speed and nozzle opening-angle on the level fluctuation were investigated while nozzle ...

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.

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 ...

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 ...
