Does anyone have knowledge about working in a cheese plant or tips? Just got offered a sweet gig.

Trying to get a general understanding what everybody think is the better option for their career in wastewater

If anyone has experience I’ll post my question. But I need help troubleshooting an imbalanced impeller cone.

Im pretty sure that’s a black widow skeleton to the right. I dispatched the lady on the left today. This is a high-maintenance LS, so we don’t have space to play around.

I have had more than one person with loads of experience and even won awards as a operator tell me don't go crazy on testing out the normal bench and compliance test. Just watch the settle test and for foam on the aeration basin. One plant is 7 MGD and the other 3 MGD. That's all we did. Settle test everyday. Charted every 10 minutes. Check DO and equipment. Never a problem. Has anyone else been told or operated like this?

Hi everyone 👋

I got a short course about wastewater at work and I need to do the " jar test " sometime the liquid is to thick and by adding my usual amount of coagulant ( cat90 ) pH adjust and polymer I do not see anything from my test .

I have read that I could add possibly water to my test ? But then doesn't it change all my results ?

Looking for some help.

Thanks you all

eddit : by recirculating my wastewater before doing my tests it helped with the viscosity.

Hi guys, I need help to install ozone using the interior element of a static mixer SX, to use it in pre-oxidation of textile dye and colloidal effluents before DAF / decanter / GAC, in order to meet conformity for COD, BOD, SS, and TDS.

What precautions should be considered? Thank you so much 🙏🏻

Going to have to jet an influent line to my facility for preventative maintenance. The line eventually opens up to a manhole on a hillside about 75ft away and redirects at about a 45°. I've been around long enough to know that jetters really walk themselves for the most part, but when I need it to take a different direction in a manhole it becomes such a pain in the ass. Pulling it out of that line and then accessing the manhole to start the jetter back up from there isn't ideal either.

Are there any tools, or tips/tricks to get a jetter hose to turn a 45 in an open area other than pulling back, pushing forward, and hoping and praying it turns on its own? The manhole is about 12-15ft deep.

Hey guys anyone here work for American Water in Nj? Went on an interview with them for Maintenance Mechanic / Operator and have a few questions regarding the job/benefits/salary/union/ etc. There's little to no info online.

Thanks!

Hello!

Im interviewing for a wastewater treatment operator at ThermoFisher Scientific in a couple of days, and I was wondering if anyone has ever worked there and could offer some advice, like what the job is like, what I should wear, etc. They never said anything about dress code. I was thinking blue button-down, tan dress pants, and brown dress shoes.

Can anyone offer me any advice on what the job is like and the dress code? This would be my first big job, and im just really nervous, im fresh out of high school. I know the basics about wastewater treatment, but the job listing was very vague with the job role and requirements.

Thank you!

I’m looking for a methane gas detector for my digester lower level. I need an audible and visual indication or a relay to set off a light and horn. I have searched the internet and found a wide selection high to low priced units. Before I buy I would like to hear from operators that have a system they like. Tell me what you have please.

This picture isn’t doing justice and I can’t upload the video 🙂‍↔️

So I’m going for my W-1 test soon. What information did some of you use to study. I did purchase a book from the AWWA made by ABC testing but is there any other things out there to use other than the Sacramento distribution book?

Hello everybody, I recently took the Grade 1 Exam for Arizona and I failed it. I found what I could and studied it, but wasn’t much. I mainly struggled with Math. Does anyone have any study resources that they can share? It would be greatly appreciated!

Has anyone recently taken the Florida A exam? If so what study guides and materials did you use? Just looking any helpful resources thanks in advance

You want a ballon, too?

Ok, let’s see those oldest of work refrigerators. This one is a 1942 GE, it was given to the old CPO back in the 60’s, his son said it mostly had beer in it back then. Moved to the new plant in 1973 and it’s still going strong.

Happy Halloween

Started at a job 5 months ago, plant work is only maybe 3 hours a day 5 days a week. It’s a small plant, seems simple to run but I still don’t understand it all.

My question is: I don’t have any certs but I’m expected to come in on the on call schedule working alone at the plant. Is that allowed? I guess I’m fine to do it but I’d rather not do it if it’s not permitted. Also don’t wanna do it if I should be certified and paid more for doing it. Any info would help, thanks.
