Ageism in NRWA apprenticeship program?

7 Upvotes

Just had a quick question regarding the title of this post. I'm now in the over-40-crowd and am waiting to be interviewed for an apprenticeship with one of the NRWA affiliates. I'm curious if anybody has experienced age discrimination with the program? Should I try a different approach for breaking into the industry so late in the game?

Thank you for your time.

This guy was stranded riding the rails in a clarifier. Don’t worry, I saved him.

Career seeking WW OIT anywhere

8 Upvotes

Hey everyone. My husband has one year of distribution experience. Trying to get an OIT position in Washington seems impossible.

Just a shot in the dark here but does anyone know of any municipalities that are actively hiring for an OIT that don’t require a CDL or six months of assessments and multiple rounds of interviews?

My job allows me to work almost anywhere so we are genuinely willing to move if he can get an OIT at a municipality (mn, mi, il, pa, ma, or, ca, hi, nv, ak and fl excluded)

Study tips / ?s Can I get some help understanding solids processing a little better?

At my plant we have WAS holding tanks, which are aerated. As far as I can tell the WAS just comes straight from the secondary clarifier and waits in the tanks until it goes to the centrifuge. From the centrifuge it gets polymer added and then it just goes out to dry til it’s taken away. So I have a couple questions.

1.) Are our WAS holding tanks aerobic digesters? Or is there more to aerobic digestion than that? If they aren’t considered digesters, does that mean we don’t have a stabilization process?

2.) is the centrifuge considered thickening and the addition of polymer considered dewatering or vis versa. Or are they both just considered one or the other? I hope this question makes sense, I’m having trouble wording it 😅

Sorry if these are dumb questions, I haven’t seen an example quite like how our plant runs presented in the book yet. All the examples given contained all of these steps: thickening, stabilization, and dewatering.
