ENE 480 Fall 2020

  The Ammonia Test Kit contains two reagents, the two reagents contain: https://www.apifishcare.com/pdf/API_LIQUID_AMMONIA_TEST_SOLUTION_1-2.pdf polyethylene glycol, sodium nitroprusside, sodium salicylate https://www.apifishcare.com/pdf/API_LIQUID_AMMONIA_TEST_SOLUTION_2-2.pdf sodium hydroxide, sodium hypochlorite Ammonia compounds (total ammonia is the sum of ammonia (NH3) and the ammonium ion (NH4+)   combine with the sodium hypochlorite to form monochloramine. Monochloramine reacts with salicylate to form 5-aminosalicylate. The 5-aminosalicylate is oxidized in the presence of a sodium nitroprusside catalyst to form a blue-colored compound (salicylic acid analog of indophenol blue). The blue color is masked by the yellow color from the excess reagent present to give a final green-colored solution. The resulting color is directly proportional to the concentration of ammonia present. You are able to calculate the proportion of the unionized ammonia (toxic...

Happy Sunday, I hope you all have been having a great week and are remaining healthy. It's been a long one, but I was able to get in a few really nice walks (my way of decompressing and destressing; I hope you all have found productive ways to do the same). I thought you might like these photos from the Children's and Healing Gardens on campus.  There were a few last minute questions regarding the lab, which I answered by email on Saturday. I'm also providing the information here: You are to analyze the bottled water samples for pH, alkalinity, and total hardness. You are then to compare your results with the analytical results available on the company's website or on the label. Separate from that you are to: Use the data provided for Mountain Spring Water to determine the total hardness (using the concentrations of polyvalent cations), carbonate hardness, non-carbonate hardness. Compare the calculated total hardness to that reported. Is there a difference? If so, w...

In communicating with API technical support about the KH kits, I mentioned the other kits we are using.  One of their scientists graciously provided information about the phosphate and nitrate/ammonia/nitrite kits. I've provided that information below. I did a full.. generalized.. write up on the phosphate kit because the ingredients were not proprietary. So to answer your question on phosphate, it is going to read the ppm of the phosphate ion itself. But keep in mind that phosphate we are talking about is orthophosphate, also known as “reactive phosphorus” but is generally used synonymously with “phosphate” The write up is below, if you want to pull some nuance out of it that might be helpful for your usage. I might also have one like this for the ammonia test kit as well, if it would be useful. The Phosphate #1 bottle contains sulfuric acid and ammonium heptamolybdate (information found here: https://www.apifishcare.com/pdf/API_PHOSPHATE_TEST_SOLUTION_1-1.pdf ) The ...

All:  The results that some of you have gotten with the API KH test has had be baffled, but upon further inspection of the API website I found this: What is Carbonate Hardness (KH)?   Carbonate hardness, also known as alkalinity, is the measure of carbonate and bicarbonate concentrations dissolved in water. These minerals are present in municipal, well, and bottled water. The level of carbonate hardness in tap and bottled water depends on the source of the water and the treatment processes it has undergone. Carbonate hardness helps stabilize pH in the aquarium. An aquarium with a low KH level will tend to be acidic. Aquariums with very low KH are subject to rapid pH shifts if not monitored carefully. Water with a high KH level usually has a high pH [1]. This actually explains the results as the KH test does not measure carbonate hardness as the test name indicates, but measures alkalinity. Carbonate hardness is NOT also known as alkalinity, it is that portion of the h...

  Hi all, The most sacred right that we as Americans have is the ability to vote! It is an act that many actually died for; yes, died for. It is an act that wasn't freely given - but was fought long and hard for. It is an act that many still fight for and other yearn for.  Protest to support the women's suffrage movement in the US For those of you that are legally afforded the right to vote in the US, I urge you to do so. I will honor all requests for accommodations to vote on Tuesday, November 3, 2020, as ENE 483 tutorial and ENE 480 Section 2 meets that afternoon. The lecture will be recorded in the morning and as will the afternoon lecture. Students can also attend Thursday's lab section.  In Michigan,these are important dates.  Please take note of them. The deadline to register online to vote is Monday, October 19, 2020. The deadline for registering by mail to vote is (postmarked by) Monday, October 19, 2020. The deadline to register in person to vote ...

 Happy Saturday, I hope all of you are doing well and even took the opportunity to enjoy the beautiful fall day.  Today's walk through Central Park South in Okemos   I received a few questions about Assignment 1 (due Sunday Sept. 20 at 11:59 pm) and I thought I would share my responses with all of you. Q1 and 2: Make sure to Interpret the statistical analysis for your reader (again, review the notes to see how in all cases, I present the null and alternate hypotheses and then interpret the analysis) Q3: Make sure you are following the approach used in the Statistics video for using the statistical test for outliers. Q4: Again, make sure to interpret the statistical analyses. Are the correlations strong, moderate, weak? Make sure to develop a correlation matrix as shown in the Statistics video. I also had a question about how long the first lab report (due Sept. 27 at 11:59 pm) should be. The introduction should be 2-3 paragraphs. The methods should be about the ...

  All There appears to be a problem with the link to the YouTube videos on Chrome. The links work when using Edge or Firefox. There are more details on the blog: https://ene480fall2020.blogspot.com/ All the videos are publicly available on my YouTube channel (Susan J Masten). Also, because of the Career Fair and the fact that many of you are graduating seniors, I have moved the Assignment 1 deadline to Sunday Sept 20, at 11:59 pm. I will go over the Lab 1 requirements in Lab today. The video from Tuesday is posted in LON-CAPA. I also recorded a video on Hardness and Alkalinity, which is posted on YouTube. Please let me know if you have any questions. Dr. Masten

Happy Sunday, This week we will begin with the first laboratory exercise. If you have not completed the safety training, please contact me asap, but definitely before beginning the lab exercise. In class, I will provide a review of hardness and alkalinity and will go over the first lab.  I have uploaded the notes on hardness and alkalinity and on the lab. I have also uploaded a video about maintaining your lab notebooks. Reminders about due dates: Safety quiz and Training certificate s : were due 9/11/2020 at 11:59 pm Assignment 1 : Statistical analysis (to be done individually): due 9/18/2020 at 11:59 pm Lab 1: Hardness and alkalinity (lab work is to be done individually, teams are to pool the data from individual work to submit one lab report): due 9/25/2020 at 11:59 pm   A number of students have mentioned that they have had difficulty accessing the videos from LON-CAPA. If this is the case, try changing browsers. I use FireFox and haven't had any trouble. A stude...

 All: There will be no class tomorrow (Thursday, Sept 10).  This will allow us to make sure Sections 1 and 2 are doing the same labs in the same week.

Reminders about due dates: Safety quiz and Training certificate s : due 9/11/2020 at 11:59 pm Assignment 1 : Statistical analysis (to be done individually): due 9/18/2020 at 11:59 pm Lab 1: Hardness and alkalinity (lab work is to be done individually, teams are to pool the data from individual work to submit one lab report): due 9/25/2020 at 11:59 pm Lab 2: Chlorine kinetics (lab work is to be done individually, teams are to pool the data from individual work to submit one lab report; note if you have different waters - the kinetics will also be different - think back to Lab 1): due 10/9/2020 at 11:59 pm Lab 3: Phosphorus/nitrogen lab  lab work is to be done individually, teams are to pool the data from individual work to submit one lab report): due 10/16/20...

Greetings, I hope all of you had a good first half-week of classes.  I posted Thursday's lecture in LON-CAPA.   I will repeat Thursday's (9/3) lecture on Tuesday (9/8), so if you attended on Thursday you do not need to attend this Tuesday. There will be no class this Thursday (9/10).  Be sure to use the time to complete your first homework (Safety quiz and EHS Safety courses). The work is due by 9/11/2020 by 11:59 pm. I ordered the new practice exam for the CE and ENE exams and once I receive that, I'll finish the FE Exam Preparation Seminar, which I'll give during one of the tutorial sessions for ENE 483 this month. Details soon. You are all welcome to attend that, irrespective of whether you're enrolled in ENE 483 or not. I will send out the Zoom link by email. If you are having trouble accessing the textbook, please let me know. I made this video for ENE 483, but it should also be helpful for you. And lastly, if you have not completed the course survey, please do...

 Greetings, I've posted the notes for tomorrow's lecture, which will be on Water Supply Design Considerations. I also pre-recorded a short lecture on The Design Process, which I uploaded to LON-CAPA and also to my YouTube channel. You will need to view the pre-recorded lecture to complete the first homework assignment.  There will be no lecture on Monday due to the holiday. Details regarding Tuesday's tutorial are forthcoming.
