In this video lecture we will be solving a numerical based on design of rapid sand filter.
This video lecture has rapid sand numerical solved in a way that leads to the rapid sand filter design calculation. Rapid sand filter design is essential for filtration of large scale water supply treatment units. This numerical also covers the under drainage system which is essential for the backwashing of rapid sand filter. Finally we calculate and design the water troughs which facilitate the backwash water out of the rapid sand filter.
