why back washing is performed in DM water plant?

Answer / rahat
Backwashing
After the resins are exhausted, the bed is backwashed.
Backwashing is carried out by a uniform upward flow of water
through the resin bed. The backwash step expands the resin
bed releasing any entrapped particulate matter & removes the
channeling in the resin column if occurred during the
service cycle.

HEAT TRANSFER - EXAMPLE 5.3 : In a cylinder with a hollow, let a is outside radius and b is the inside radius. In a steady state temperature distribution with no heat generation, the differential equation is (d / dr) (r dT / dr) = 0 where r is for radius and T is for temperature. (a) Integrate the heat equation above into T(r) in term of r. (b) At r = a, T = c; at r = b, T = d. Find the heat equation of T(r) in term of r, a, b, c, d.
