Consider the design of
a wastewater treatment plant (wwtp) for a community with average
daily
and peak hourly wastewater design flows of qav m3/day and qpeak
m3/day. the raw sewage has an
average of bodav mg/l bod5 and ssav mg/l of suspended solids.

(e) determine the return (recycle) flow rate in cubic meters per
day (qr).
(f) determine the volumetric bod loading to the aeration tank in kg
bod m-3 d-1.
(g) determine the food to microorganism ratio (f/m) for the
aeration tank in kg bod d-1 / kg mlvss.
(h) determine the design hydraulic detention time (hrt) in
hours.

Name the bone/structure/process that fits the following description: a) a bone with a complex shape. b) found in the medullary cavity. c) a large, rough process. d) it is thin, like a plate. e) shaft of a long bone. f) a mature bone cell. g) a large, round, smooth process. h) it covers outer surface of bone. i) a shallow depression on surface of bone. j) a roughly cube-shaped bone. k) the covering of epiphysis. l) a very narrow ridge of bone. m) space between lamellae for an osteocyte. n) chamber within diaphysis o) also called wormian bone. p) it secretes new matrix. q) end of a long bone. r) a small, round hole. s) a matrix, arrangement in spongy bone. t) it is a chamber within a bone. u) a network allowing osteocytes to receive nutrients. v) one example is the patella. w) it houses artery, vein and nerve. x) almost flat, smooth surface of a bone. y) a narrow, pointed process.
