Multigrade Sand Filter also consist of a vertical or
horizontal pressure vessel with a set of frontal pipe work
and valves, media consist of different sizes and grade mixed
and supported by layers of pebbles and gravels, a top
distributor to distribute the incoming water uniformly
throughout the cross section of the filter, and an under
drain system to collect filtered water.

This filter performs at a substantially higher specific flow
rate than conventional filters. The basic difference between
Pressure Sand Filter (PSF) and Multigrade Sand Filter (MGF)
are media used in vessel and velocity variation.

and
Dual media filter contain anthracite in combination with
sand supported by pebble and gravels. Theses filter consist
of a layer of anthracite (1.25-2.5mm) resting on a layer of
fine sand (1-1.5mm) Anthracite is coarse and has more dirt
holding capacity as compared to sand.

Question 53 - In the purchase of a machine with a period n = 8.5 years, the minimum attractive rate of return, i = 12 %, the cost P = $55000, F = $4000 is the salvage, annual maintenance A = $3500. The return of the investment or equivalent uniform annual benefit is $15000. The equivalent uniform annual cost is P (A / P, i, n) + A - F (A / F, i, n). The investment is considered acceptable only when equivalent uniform annual benefit is greater than the equivalent uniform annual cost. From the compound interest table, (A / P, i = 12 %, n = 8 years) = 0.2013, (A / P, i = 12 %, n = 9 years) = 0.1877, (A / F, i = 12 %, n = 8 years) = 0.0813, (A / F, i = 12 %, n = 9 years) = 0.0677. Prove by calculations whether the investment above is acceptable.
