Thread Content
The last edit to this post was made by Zaihui Kangqiao on 2015-12-26 at 13:21. The Chemical Engineering Theory section is now launching a \"One Question per Day\" activity aimed at helping everyone reinforce their basic knowledge in chemical engineering. Subsequent series such as \"Chemical Engineering Principles,\" \"Mass Transfer and Separation,\" \"Chemical Engineering Thermodynamics,\" and \"Chemical Engineering Processes\" will also be introduced. We hope for your active support! 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! Participation earns 3 wealth points, with an additional 4 wealth points for correct answers~~~ Short answer question: What are the functions of backwashing during the regeneration process of an ion exchanger? Answer: 1) Remove dirt and suspended particles that accumulate during operation. 2) Expel air. 3) Loosen the ion exchange resin that becomes compressed during downward backflow. 4) Used to stratify the resin
1) Remove dirt and suspended particles that accumulate during operation 2) Expel air 3) Loosen the ion exchange resin that becomes compressed during downward backflow 4) Used to stratify the resin
1. Remove dirt and suspended particles accumulated during operation. 2. Release air. 3. Loosen the ion exchanger that becomes compressed during downward backflow. 4. Used to stratify the resin.
Backwashing is mainly intended to remove the dirt and suspended particles that accumulate during operation； Remove air ； Loosen the ion exchanger that becomes compressed during downward backflow ； Used to stratify the resin.
1) Remove dirt and suspended particles accumulated during operation； 2) Remove air ； 3) Loosen the ion exchanger that becomes compressed during downward backflow ； 4) Used to stratify the resin
Remove broken resin and some solid impurities
