Weekly message 10/4/2020

Happy Sunday,

Well we don't have a blue sky today, but at least it isn't raining (now)!

As we move into several units (sedimentation and granular media filtration) that are based on fluid mechanics, I thought I'd give you this bit of information I gleaned this morning from colleagues on Twitter and how prairie dog burrows are better ventilated than most classrooms.

We will continue the unit on sedimentation this week. I posted a handout in the Lecture (powerpoint) folder on LON-CAPA. We'll work through this problem either Monday or Wednesday.

On Tuesday, Paul Larios, MSU CEE alum will speak to us during the tutorial.  We'll start his lecture at 10:30 am.  He will speak about Water Resources Engineering in the Hudson Valley, NY. and will discuss four recent WTP/WWTP jobs he has worked on. Two involve the use of NYC water supply. He will also share his experience with Agua Clara Cornell and their technologies, and provide some insight/advice that he has garnered since taking ENE 483.  As usual, the lecture will be recorded.

The homework on softening, along with Tutorial Assignment 1(drawing of a paddle wheel flocculator based on provided specifications), are due on Wednesday at 11:59 pm. I will hold office hours Monday and Wednesday at 4-5 pm. The Zoom link is provided in my weekly email message.

Finally, you should be working on the MiniDesign Phase 1 assignment with your design teams. The assignment is due Wednesday 10/14/2020.  There will not be a homework assignment due that week; however, I will open the sedimentation homework folder in the next day or two.

And don't forget to complete the participation question that is due tonight (10/4/2020 at 11:59 pm).

Fall colors make me smile, as does being able to go for walks. Photo taken Saturday 10/3 on the boardwalk on Okemos Rd. in Okemos, MI

On my afternoon walk today, I wandered into a neighborhood that was having an Oktoberfest celebration. Families had tables set out and were sharing treats with neighbors and those walking though. This family allowed me to take their photo to show you another thing that made me smile. Oh, and yes, the cat is theirs.



Stay well!

Happy Saturday! I hope all of you are staying well.  We now have less than one month left of classes! On Monday we will take a break from regular lecture and do a group activity.  As such, Monday's lecture will not be recorded. On Wednesday we will start a unit on ion exchange. Following that we'll look briefly at absorption and then membrane processes. We'll finish with residual management. Now here is a photo from the absolute coolest plant I've ever toured. The Henriksdal Wastewater Treatment Plant is in Stockholm, Sweden and it is build within a mountain. Yes, totally carved out into a mountain. The workers use bicycles to get around the tunnels (which are about 9 km long). Just a few reminders for the next two weeks: Sunday 11/15: Participation Question is due at 11:59 pm Monday 11/16: Office hours 4-5 pm (I added a link to the Zoom meeting in the main folder on LON-CAPA). Tuesday 11/17 10:30-11:30 am : Danielle Yoon, Fishbeck Engineers: Financing Water and Was...
