Influence of physical clogging on filtration performance of soil-geotextile interaction

Geosynthetics International, 2022
During the past four decades the use of nonwoven geotextiles as filter materials in geotechnical works has experienced a marked increase. In this study, the water permeability coefficient of nonwoven geotextiles after 23 years of exploitation in drainage system was determined to evaluate the influence of physical clogging on filtration performance of ...

Predicting physical clogging of porous and permeable pavements

Journal of Hydrology, 2013
Summary Porous pavements are easily retrofitted, and effective in improving water quality and hydrology, but prone to clogging. Despite being a major determinant in the lifespan of porous pavements, there is limited information on the physical clogging processes through these systems.

Permeability Reduction of Soil Filters due to Physical Clogging

Journal of Geotechnical and Geoenvironmental Engineering, 2000
Soil filters, which are commonly used to provide stability to the base soils in subsurface infrastructure, are prone to long-term accumulation of fine micron-sized particles. This causes reduction in the permeability, which in turn may lead to intolerable decreases in their drainage capacity.

A detailed investigation of physical and biological clogging during artificial recharge

Water, Air, and Soil Pollution, 1987
An attempt was made to study the physical and biological clogging during artificial recharge with an experimental model that simulates the artificial recharging practice by considering factors such as effective infiltration rate, media size and depth, and inundation period.

Physical Clogging of Uniformly Graded Porous Media Under Constant Flow rates

Transport in Porous Media, 2017
This 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.

Comparison of clogging induced by organic and inorganic suspended particles in a porous medium: implications for choosing physical clogging indicators

Journal of Soils and Sediments, 2018
Water from different sources generally contains different kinds of suspended particles, which introduces the challenge of how to control physical clogging during managed aquifer recharge (MAR). Suspended solid concentration (SS) and turbidity (NTU) are widely recognized as indicators of physical clogging potential.

Physical clogging of soil filters under constant flow rate versus constant head

Canadian Geotechnical Journal, 2005
In 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.

Physical, chemical and biological emitter clogging behaviors in drip irrigation systems using high-sediment loaded water

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.

The Role of Physical Therapy in Reducing the Recurrence of Clogged Milk Ducts and Subsequent Mastitis

Journal of Women's Health Physical Therapy, 2022
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, 2016
Dripper 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.
