Theoretical and experiential value of reverse osmosis membrane cleaning fluid
Sep 15,2018
Generally, reverse osmosis equipment is equipped with on-line cleaning device randomly, but because of the cost, many cleaning devices do not meet the cleaning requirements. This situation is often ignored.
1. Theoretical value of reverse osmosis membrane cleaning fluid
V= 1.2(V1+ V2)
V1 is pressure vessel space（m³）
| Membrane number | 1 | 2 | 3 | 4 | 5 | 6 | 1 | 2 | 3 | 4 | 5 | 6 |
| Membrane space | 0.03 | 0.06 | 0.09 | 0.13 | 0.16 | 0.19 | 0.01 | 0.02 | 0.02 | 0.03 | 0.04 | 0.05 |
| 8' | 4' | |||||||||||
V2 is pipeline empty volume
V2=Lπ d2/4
Among them: L = total length of cleaning pipes.
D = pipe diameter for cleaning.
2. The amount of reverse osmosis membrane cleaning fluid experience value.
For normal contamination, 8.5 liters of cleaning fluid are usually prepared for each 4-inch membrane element, and 34 liters for each 8-inch membrane element to calculate the volume of the reverse osmosis tank.
For serious contamination, 16 liters of cleaning fluid are prepared for each 4-inch membrane element, 55 liters for each 8-inch membrane element, and the volume of the cleaning box and the amount of cleaning fluid are obtained.
