Question

$1.$ How much can grit chamber remove from the wastewater

$2.$ Calculate remaining volume $(1000$ cu m $-$ volume of grit removed$)$

$3.$ How much grit can the clarifier remove

$4.$ Calculate remaining volume $($Volume from no$\mathrm{.}2-$ volume of grit removed$)$

$5.$ Solve for the piping dimensions and pressure difference for each primary process in terms of the grit that they removed.

you are free to get values from internetHorizontal velocity $=0\mathrm{.}25-0\mathrm{.}5\frac{m}{s}$

Detention time $=45-90s$

Surface loading rate should not exceed $1200\frac{m^3}{m^2}\frac{?}{d}$

Water Depth $=0\mathrm{.}6-1m$

Width of chamber $=(1-2)$ water depth

Vertical velocity $=2c\frac{m}{s}$ for particles greater than $0\mathrm{.}2mm$

Length of chamber $=(20-30)$ water depth

Amount of grit settled $=100-250\frac{\text{I}}{1000}\frac{m^3}{d}$
