This post was last edited by “Back to Cambridge” on January 14, 2016, at 17:52. Starting today, the Chemical Engineering Theory section is launching the “Question of the Day” activity, aimed at helping everyone reinforce their fundamental knowledge in chemical engineering. Subsequently, series such as “Principles 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: Under what circumstances should the operation of the mixed-bed be stopped? Answer: 1) Failure of the high-mixing unit, with effluent water quality exceeding standards; 2) Iron content in the inlet water ≥ 1000 ppb; 3) Inlet water temperature ≥ 50°C; 4) The corresponding unit is taken out of service; 5) Pressure difference between inlet and outlet ≥ 0.35 MPa; 6) Defects in the high-mixing unit that render it unsuitable for operation
Under what conditions should the operation of the mixed-bed be stopped in case of high mixing? 1) High-mixing failure, effluent water quality exceeds standards ; 2) Iron content in the inlet water ≥ 1000 ppb ; 3) Inlet water temperature ≥50℃ ; 4) Isolation of the corresponding unit ; 5) Import and export pressure difference ≥ 0.35 MPa ; 6) The high-mix system develops defects that make it unsuitable for operation.
I don’t know what “high mix” means. Q just posted a reply – why isn’t the browser responding?
2) Iron content in the inlet water ≥ 1000 ppb; 3) Inlet water temperature ≥50℃ ; 4) Isolation of the corresponding unit ; 5) The pressure difference between inlet and outlet is ≥0.35 MPa. 6) Defects that render high-speed mixing unsuitable for operation occur ;
Operation should be stopped when the following situations occur: 1) The high-mixing unit fails, and the quality of the effluent exceeds the standards; 2) Iron content in the inlet water ≥ 1000 ppb ; 3) Inlet water temperature ≥50℃ ; 4) Isolation of the corresponding unit ; 5) The pressure difference between inlet and outlet is ≥ 0.35 MPa. 6) Defects that render high-speed mixing unsuitable for operation occur
