Master granular media filter configurations, material characteristics, and bed construction in drinking water treatment facilities. Practice 10 original calculation and diagnostic problems covering rapid sand, dual-media (anthracite/sand), and multimedia (anthracite/sand/garnet) stratification, effective size ($d_{10}$), uniformity coefficient ($UC = d_{60}/d_{10}$), underdrain systems (Wheeler, Leopold blocks), and surface loading rates. Every item includes full step-by-step unit cancellation and distractor rationales.

Prerequisites: Basic water treatment math and hydraulics.
