Irrigation Water Conveyance and Application Methods
Subtopic: Surface, sprinkler and micro irrigation methods
Question Statement:
In drip irrigation systems, the primary filter installed immediately downstream of the pump to remove heavy suspended sand and gravel particles from surface canal water using vortex action is a:
Options:
(A) Hydrocyclone (sand separator)
(B) Media (gravel/sand) filter
(C) Disc filter
(D) Screen filter
Answer Key:
A
Step-by-Step Solution & Explanation
A hydrocyclone uses centrifugal vortex velocity to spin out coarse inorganic suspended solids like sand and silt (gt; 75\text{ }\mu\text{m}$), collecting them in an underflow collection chamber before the water enters media and screen filtration units.
