A water treatment plant is designed to treat 1 m³/s of raw water. It has 14 sand filters. Surface area of each filter is 50 m². What is the loading rate (in (m³/days.m²)) with two filters out of service for routine backwashing?
-
- 214 m³/day.m²
- 124 m³/day.m²
- 174 m³/day.m²
- 144 m³/day.m²
Correct Option: D
| Hydraulic loading rate = | ||
| A |
| = | m³/sec.m² | |
| 12 × 50 |
| = | m³/day.m² | |
| 12 × 50 |
= 144 m³/day.m²
