Clogging formation and an anti-clogging method in subsurface irrigation system with porous ceramic emitter

Agricultural Water Management, 2021
Abstract Emitter clogging negatively affects the performance of subsurface drip irrigation systems. The porous ceramic emitters of a subsurface irrigation system were investigated to identify the reasons for emitters clogging. Using 2-year operational data in an apple orchard, the soil water content and the emitters discharge were measured, the ...

Reclaiming Partially Clogged Trickle Emitters

Transactions of the ASAE, 1977
ABSTRACT A trickle emitter system, which had become partially clogged after 2 years of operation even with extensive water filtration, was reclaimed suc-cessfully by treating the entire system with concentrated hypochlorite and acid solutions. Chemical cost per emitter was less than replacement cost for the emitter and supply tubing.

SIMULATING EMITTER CLOGGING IN A MICROIRRIGATION SUBUNIT

Transactions of the ASAE, 2001
A mathematical model was developed to simulate the effects of emitter clogging on subunit hydraulics. The model consists of a set of equations based on fundamental hydraulic principles and inlet lateral discharge relationships, and uses a nonlinear equation solver.

Anti-clogging performance optimization for dentiform labyrinth emitters

Irrigation Science, 2020
It is of great scientific significance to reveal the flow characteristics of dentiform emitters and to optimize the channel structure of emitters to improve the anti-clogging properties of emitters, which contribute to improving the working performance of irrigation systems. The study was carried out using computational fluid dynamics (CFD) simulations,

Emitter Clogging Effects on Trickle Irrigation Uniformity

Transactions of the ASAE, 1981
ABSTRACT A simulation model for emitter clogging on trickle irri-gation systems was developed. Hypothetical emitter populations were generated from specific initial values for the average discharge rate and coefficient of variation of the emitter. Various combinations of clogging were in-troduced into the model to determine how they affected average ...

Emitter clogging characteristics under reclaimed wastewater drip irrigation: a meta‐analysis

Journal of the Science of Food and Agriculture, 2022
AbstractBACKGROUNDAlthough reclaimed wastewater drip irrigation (RWDI) is an effective technology for alleviating agricultural crop water stress and protecting the environment, the reclaimed wastewater (RW) may cause emitter clogging. Discharge ratio variation (Dra) and coefficient of uniformity (CU) play a key role in exploring the clogging degree of ...

Hydrogen Peroxide Treatment of Manganese Clogged SDI Emitters

2009 Reno, Nevada, June 21 - June 24, 2009, 2009
Dissolved manganese in irrigation water has contributed to emitter clogging of subsurface drip irrigation (SDI) systems in the Texas High Plains. During the 2002 growing season, areas of clogged emitters occurred in a 6-ha research field at the Texas AgriLife Research and Extension Center at Halfway, Texas. Water samples from the irrigation source were
