Thread Content
This post was last edited by “Back to Cambridge” on January 13, 2016, at 16:37. Starting today, the Chemical Engineering Theory section will launch the “Question of the Day” activity, aimed at helping everyone reinforce their basic knowledge of chemical engineering. Subsequently, series such as “Fundamentals of Chemical Engineering”, “Mass Transfer and Separation”, “Chemical Thermodynamics”, and “Chemical Process Technology” will also be introduced. We hope for your active participation! Wishing you all a Merry Christmas~~ For replies to the “Question of the Day” activity, answers can be viewed directly; however, the thread will be closed after one day! ! To encourage everyone’s continued participation this year! Participation earns 3 wealth points, with an additional 4 wealth points for correct answers~~~ Short answer question: What precautions should be taken when performing a thorough backwash of an ion exchanger? Answer: 1) During a heavy backwash, someone must be on site to supervise. 2) During a heavy backwash, the flow rate should be increased gradually to remove air. 3) A light backwash should be performed before a heavy backwash. 4) Try to reach the highest possible level during the heavy backwash to ensure thorough cleaning
1) During a thorough backwash, someone must be on site to supervise. 2) During a thorough backwash, the flow rate should be increased gradually in order to remove air. 3) A minor backwash should be carried out before a thorough backwash. 4) Efforts should be made to reach the highest possible level during the thorough backwash to ensure complete cleaning
What precautions should be taken when performing a heavy backwash on an ion exchanger? When performing a heavy backwash on the ion exchanger, the following points should be noted: 1) During a heavy backwash, someone must be present on site to monitor and prevent any failures from occurring ； 2) During heavy backwashing, the flow rate should increase from low to high in order to remove air ； 3) Perform a minor backwash before a major backwash ； 4) The maximum height should be achieved during large-scale backwashing to ensure thorough cleaning ；

What precautions should be taken when performing a heavy backwash on an ion exchanger? When performing a heavy backwash on an ion exchanger, the following points should be noted: 1) Someone must be present on site to supervise the process during heavy backwashing. 2) During heavy backwashing, the flow rate should be increased gradually, and air must be removed. 3) A light backwash should be carried out before the heavy backwash. 4) The backwash should be conducted to the highest possible level to ensure thorough cleaning

1. During heavy backwashing, the flow rate increases from low to high; air must be removed. 2. During heavy backwashing, someone must be on site to supervise
