What is the wastewater stripping side draw ratio? ? ? ?
Ratio of side-line withdrawal to feed rate
1. Side stream extraction ratio = Side stream extraction amount/Processing amount. 2. Under normal circumstances, the control of the side-line extraction ratio should be based on the ammonia nitrogen content determined through the analytical testing of the purified water. 3. When the side-line extraction ratio is too low, it can result in excessive ammonia nitrogen levels in the purified water ； When the side-line extraction ratio is too high, H2S can be present in the gas extracted from the side line; in severe cases, ammonium hydrosulfide salts can form, blocking the pipelines.
Side stream amount/(hot feed + cold feed). At that time, our side-stream flow rate was in standard cubic meters; we calculated it using the molecular weight of water (18), with ammonia having a molecular weight of around 17 as well. We divided the volume by 22.4 and then multiplied the result by 18. Finally, the mass ratio is obtained.
10:1 (cold water plus hot water to the amount drawn from the top)
