Cartridge filters are known as edge filters on account of the fact that the_________________?
Show answer Hide answer
Answer: C. Bulk of the solids are removed at the periphery of the disks
Explanation
Cartridge and edge filters utilize stacked disks or tightly wound wire elements. Solid impurities are trapped and removed at the outer periphery or edges of the disks. Option C accurately describes why these units are commonly designated as edge filters. Filtration mechanisms include cake filtration, deep bed filtration, and surface straining. Edge filters provide fine clarification by forcing liquid through narrow peripheral gaps. Stacked metallic or paper disks can be easily cleaned by rotating internal scraper blades.
Lubricating oil systems in heavy machinery use edge filters to remove contaminating grit. Fuel filtration units rely on cartridge designs to protect sensitive injection nozzles. Edge filters offer compact, high-efficiency clarification for low-solids industrial liquids. Disks having sharp edges do not define the operational principle of edge filtration. Solids are indeed deposited at the peripheral edges of the filter element disks. Option D is incorrect because option C correctly explains the term edge filter.

Q1. At low Reynolds numbers, fluid agitation power (P) in stirred tanks becomes independent of inertial forces. In this limit, identify the satisfied relation: Po = ρ/ρN3 D5 (Power number), Re = ρ N D2/μ (Reynolds number), N = impeller speed, D = impeller diameter ?
Show answer Hide answer
Answer: B. Po ∝ Re0.0
At low Reynolds numbers in the laminar flow regime, the power number is inversely proportional to the Reynolds number, yielding a slope of -1.0 on a log-log plot.
