Anyone have experience using "RYDLYME Biodegradable Descaler" for struvite removal on their equipment?
De-watering equipment (belt press) is due for a cleaning soon. Management is open to new ideas on how to tackle this project. The main challenge in this gig is the removal of struvite buildup.
Would this product help with significantly loosening or softening the calcium deposits?
Is there any bi-products or major cons of using this that is of concern to sludge processing, pressed water, or equipment?
I took a brief look at the compound's SDS information and nothing appears to have drawn any major concern in regards to how it could potentially react with our equipment and process. looking for any perspective from fellow operators who've used this before. Thank you
There is a job offer for an anaerobic digestion,for a food waste facility. They are paying pretty good and been hiring for awhile, does anyone have any experience and or/ knowledge to how it is compared to traditional wastewater plants.
Hi all. I'm writing my collection level 3 exam next month here in Ontario, Canada and I'm wondering if anyone has written it before and has come up with a list of questions? I wrote it once already and have questions to share so if anyone is in my situation and wants to help or pass, I'm your guy lol. Cheers!
A: Lake B: Shallow well C: Deep well with gravel D: Spring
I may or may not have gotten a question like this. I know lake is not correct but out of the three?
I chose spring because the deep well with gravel threw me off but I’m pretty sure I got it wrong and deep well was correct answer.
We have issues with leafs every fall, and are trying to come up with some solution. We had a leaf guard that was about 4 inches wide that was frequently under or over the water line and just let leafs go right by, so we installed a much wider 13 inch leaf guard this week. It's now creating a sort of vortex and sucking more leaves underneath it. What do you guys have or do at your plant to stop leaves? I'm having to drive down to the intake every hour to rake the screen
We'll probably be trying to capture them soon so they don't freeze in the winter. But they are super cute.
It’s pretty in the picture, but it was awesome in person!
Can someone please explain this meter reading to me? The manual says 1,000 gallons per sweep hand revolution. Does that mean this is showing 319,787,900 gallons? Our calculation sheet would report this as 31,978,700. I think our sheet may be wrong.
A plant in the keys.
Just cuz we work with the backend of things doesn't mean it's all bad
Anyone have experience with hydraulic loading and POTWs? Potentially with industrial users, and stormwater mixing with their wastewater discharge?
I’ve noticed most POTWs, permit, codes, somewhere - specific to industrial users - they have language regarding prohibition of stormwater from entering wastewater treatment and being discharged.
I’m trying to understand more about this and if there are developed standards, approach or determination to what may be an allowable amount of stormwater, as it’s virtually impossible for some facilities to completely eliminate stormwater. That the nature of operations and activities, along with design of the facility, an incidental and insignificant amount may get commingled.
I was on a late night rabbit hole one day and swear I came across a presentation discussing this, possibly with a limit such as 0.5% of total process wastewater discharge, that would be allowed. But I can’t find that again.
I know that the City of Portland has in their code that industrial facilities must reduce impervious footprint to max of 1000 sqft, or demonstrate infeasibility. Most I’ve found don’t seem to quantify such as this, they just leave open and vague as if no stormwater whatsoever is permitted.
Hey ya'll, I wanted to apologize for my post the other day. I snapped off some rude shit to a dude that made a joke and I'm sorry. I'm not normally a dick like that, my doctors took me off my mental health meds last month when my kidneys shut down momentarily and they haven't found safe replacement meds for me yet, and I've been struggling with social cues and public interactions ever since and I'm super stressed out trying to keep this place going by myself. Not that that's an excuse for my rudeness, but I've decided that after this post I'm gonna stay off social media till I get myself sorted out and can interact with ya'll on a semi-normal basis. So again I'm sorry if you saw it and were angered by it. I'll do better.
Geese overnighting in the clarifier.
Hello everyone, I’m a Tennessee operator, I currently have my grade 3 license with 7 years experience. Today I failed the grade 4 for the second time. First time was a 61% today was a 67%. A few weeks ago I took the cram course and they gave us (the class) 300 questions to study. I memorized every single one. On the 4 there was about 20 of those questions on there. I know they have officially confirmed a new test will start in the spring of 2025, but my question is has anyone ever contacted the board and had questions challenged and gotten there score changed? Being so close to passing and on top of feeling like I’ve studied everything I can get my hands on, Sacramento, wef, cram course and can’t officially get that 70%
After some time trying to get my foot in the door, I finally got offered a Maintenance Technician Internship at my local ww plant. Super excited to finally get an opportunity to learn the trade and hopefully build a long-term career in the field. I have a couple questions. Thanks!
Do you have any tips for someone just starting out?
Can a Maintenance Technician role lead into becoming a ww operator?
I took a test recently that had several of those questions like
“A storage tank with dimensions of LxW is filling a day tank with dimensions of LxW. If the day tank rises 3 ft, what is the draw down of the storage tank?”
I always struggle with these questions. Can anyone please help me break it down in simple terms?
Hey y'all. My wife is a school teacher and asked me to volunteer for career Day this year. I'm trying to figure out the best way to present what we do without grossing them out too much or losing them with the science. I'll probably be presenting to a 4th/5th grade class.
Anyone ever do one before? I was talking about it with the plant supervisor and he suggested I bring samples from different parts of the plant to show how the process evolves(clear bottles and bagged so the risk of spills is mitigated). I plan on giving them the rough outline of how the process works. And some photos of microscope slides/bugs that I'll display on the projector.
Anyone have any wisdom?
Hey everyone I had this exact same question on my test and was wondering if anyone knew the answer. Thanks!
“What should the seal pressure be if pumping a corrosive liquid through a centrifugal pump?“
A. -9.9 to -5.0 psi B. -4.9 to 0 psi C. 0 to 4.9 psi D. 5 to 9.9 psi
What would be the better option? Working for a water district or being a pipe layer for wet underground construction in the private sector who does public jobs
Hey everybody, posted yesterday about which you would pick water vs wastewater for an OIT position. Reporting back to say I was offered both positions and decided to go with wastewater! Looking for any tips, needs to have or training guides. Thanks everyone!
Hi all,
I'm currently a 3rd year pursing my bachelors (environmental but not wastewater focused) and have some experience in sampling from environmental consulting. I would love to do an internship in wastewater! I'm in western Canada but am open to working just about anywhere including territories. I see alot of open positions for operators but few entry/training positions. I am also open to taking the educational component at BCIT because it's online however that program is a very small admission size and it would be a bit before I get in. What is your guy's advice for landing a job in this scenario? Is it worth it to phone into places and ask if they'd take me on?
Thanks so much!
What do people use to seed their BOD's with. our lab is looking for different better options. thanks
Hey guys! I’m new to the industry. Today I was working with my co worker on a boat lifting and cleaning the aerators tubs in our ponds. It got messy. I managed to get pond sewage water in my lip and a lot of waste water on my wrists when it got exposed. Should I go to the hospital or am I over reacting ?
Edit: it was that black stuff in the water…
Anyone else want an emotional support water bear? Just me? I couldn’t believe this was a real thing so I googled it and it is. I found one at my first plant and I became the Hero for like a week rofl
