This post was last edited by Zaihui Kangqiao on 2016-1-13 at 16:39. The Chemical Engineering Theory section is now launching a \"One Question per Day\" activity to help everyone reinforce their basic knowledge in chemical engineering. Subsequent series will include those on \"Principles of Chemical Engineering\", \"Mass Transfer and Separation\", \"Thermodynamics in Chemical Engineering\", and \"Chemical Process Engineering\". We hope you will give it your active support! Wishing everyone a happy Christmas! Answers to the questions in the \"One Question per Day\" activity can be viewed directly, and the thread will be closed after 1 day ! To encourage continued participation from everyone this year! You get 3 wealth rewards just for participating, and an additional 4 wealth points for correct answers~~~ Short answer question: What are the reasons why the layering boundary during backwashing of a mixed-bed filter is not clear? Answer: 1) Insufficient backwashing intensity 2) Improper adjustment of backwashing flow rate 3) Severe resin fragmentation 4) The resin has not completely lost its effectiveness
①The backwashing intensity is insufficient; ② The backwashing flow rate is not properly adjusted; ③ The resin is severely damaged; ④ The resin has not completely lost its functionality.
①The backwashing intensity is insufficient; ② The backwashing flow rate is not properly adjusted; ③ The resin is severely damaged; ④ The resin has not completely lost its functionality.
1) Insufficient backwashing intensity 2) Improper adjustment of backwashing flow rate 3) Severe resin fragmentation 4) Resin has not completely failed
What are the reasons for the unclear stratification interface during backwashing of mixed-bed resins? 1) Insufficient backwashing intensity 2) Improper adjustment of backwashing flow rate 3) Severe resin fragmentation 4) Resin has not completely failed

What are the reasons for the unclear stratification interface during backwashing of mixed-bed resins? Answer: 1) Insufficient backwashing intensity 2) Improper adjustment of backwashing flow rate 3) Severe resin fragmentation 4) The resin has not completely lost its effectiveness
1. Insufficient backwashing intensity; 2. Improper adjustment of backwashing flow rate; 3. Severe damage to the resin; 4. The resin has not completely lost its functionality
①The backwashing intensity is insufficient; ② The backwashing flow rate is not properly adjusted; ③ The resin is severely damaged; ④ The resin has not completely lost its functionality.
