Thread Content
This post was last edited by “Back to Cambridge” on June 13, 2016, at 17:02. Starting today, the Chemical Engineering Theory section is launching 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 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! You get 3 wealth rewards just for participating, and an additional 4 wealth points for correct answers~~~ Short answer question: What are the requirements for the quality of the chilled water used in our factory? DD≤2us/cm Cu≤40ug/L PH＞6.8
DD≤2us/cm, Cu≤40ug/L, PH＞6.8
1) The cooling water should be transparent, pure, and free of mechanical impurities and particles. 2) The conductivity of the cooling water should be less than 0.5 us/cm during normal operation. 3) The hardness of water should be controlled to no more than 10 ug/L. 4) The pH value is required to be neutral, specified between 6 and 8.
DD≤2us/cm Cu≤40ug/L PH＞6.8
Anion exchange resin failure: copper ions at 200 milligrams per DD, ≤2 us/cm; Cu concentration ≤40 ug/L; pH >6.823
