Thread Content
The last edit to this post was made by Zaihui Kangqiao on 2017-5-22 at 13:52. 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 \"Principles of Chemical Engineering\", \"Mass Transfer and Separation\", \"Thermodynamics in Chemical Engineering\", and \"Chemical Process Engineering\" will also be introduced. We hope for your active support~~~ Replies to the \"One Question per Day\" activity can be viewed directly; the thread will be closed after 1 day! ! To encourage everyone’s continued participation this year! You get 3 wealth rewards just for participating, and an additional 4 wealth points if you answer correctly~~~ Short answer question: What is the main function of activated carbon filters in water treatment equipment? Dechlorination and removal of organic matter
1. Reducing COD – of course, this should be done when the level of COD is low; for example, reducing it from 100 to 50. 2. Adsorbing heavy metal ions – activated carbon can adsorb almost all heavy metal ions, and given suitable conditions, it achieves a fairly good treatment effect. 3. Decolorization to reduce the color intensity of wastewater.
