What are your high and low D.O. Set points this time of year for batch reactors?

Got the opportunity to start going to school for free and get my licenses. But read in labor bureau stats that the outlook for operators is on a decline because of automation. What’s everyone’s take on that.

I'm looking for a course that isn't online. I just can't get into online courses. I would much rather go to a physical location with an actual instructor to do a class. Does anyone know of any schools offering anything in person?

Has anyone recently went through this process, and care to share their experience?

What's your exlerience with concrete tank repairs using Belzona and how much did it cost per squarefoot? One of tanks is showing spalling and cracks.

I was curious if anyone, on top of already working a plant full time, also does any package plants part time? It’s been something I was considering because even with the on call where I’m at it’s pretty chill. I’m located in Florida If that helps anyone answer the question.

I’ve been in a pretreatment for about 3 years now and we always have used polymer straight from the bag during our jar tests and 95% always shows needing more of this one chemical. I was just curious if we needed to pre mix the solution and use that in the jar tests? Thanks much appreciated

Hey all - just theory crafting.

I have a sensor that is prone to bridging when in contact with metal salts (specifically ferric), do you think installing a cathode upstream of the sensor will protect it?

Im currently studying for my OIT which i write April 9th. Im taking a water treatment and pollution control course thats a part of an environmental tech program which is essentially my only study material other than my ELC textbooks from my ELC.

My professor is a great guy and was a great operator but is a bit unorganized and openly admitted he cant cover all the material before our writing date. So im pretty stressed about getting the 70%

Im trying to compile a list of potential OIT questions to study from if everyone/anyone could leave sone for me, especially ones that mightve stumped you or caused confusion.

Or any tips would be nice!! Lol Thanks so much!

Lets all email BC Waterjobs and tell them to switch back to the old format. This new one sucks and barely works.

contactjobs@bcwaterjobs.com

After that, lets all go on strike and get paid what we deserve in this industry!

If anyone has some materials/ questions for ABC test 3 ww collection. Please dm Thanks in advance!

Our HFS feed lines need sealing. Are there any products you guys can suggest?

Hi all!

I just recently found this community.

I am curious to hear your feedback on lead times for waste water pumps! What brands are your go to? What are acceptable leadtimes for the market you see for standard offerings, what accessories are needed, etc.

Yes I am in supply chain and I always was curious to hear from someone other than my sales guys. So why not ask the community here 😁

Is there a good way to wash polymer off of my personal clothes? Will it affect my washing machine? I’ve seen the mess it makes and I’m worried if I put it in my washer, it’ll be a mess.

I have been approached by a small drip field system owner and they want me to be a contract operator for their system. Collection and operations. They have around 100 hook ups in the subdivision.

Do I need a contractor license in Tennessee?

Do any of you all have any experience with this? I’m very interested but I have always operated as an employee.

I'm a software developer who works for a water / wastewater utility in Georgia.

I coded some internal software to manage compliance reporting. Drinking water and lift stations are supported. I will be working with an operator to integrate wastewater, as soon as I push out our update for the EPA Service Line Inventory.

My company will pay for the Class 3 Water and Wastewater certifications. Would it be a good idea to get these?

I'm also thinking about minoring in Chemistry, if I go back to school. Does that sound like overkill?

Thanks.

I know a handful of you have been lucky enough to work with these POS. What is your trick to get the pucks to feed down to the water without getting hung up in the hopper? Seems like the pucks get damp and then dry out between pumping cycles and get stuck to the walls of the hopper.

I just found out Veolia has free online training courses for wastewater. Link

I have just skimmed but thought could be helpful and pretty cool!

Specifically, why not take anaerobically digested sludge? Every time I see an operator get asked if their Plant will accept digested sludge, their face scrunches up and they are either really reluctant or they say no.

Does it matter where it's discharged, headworks vs digester? Does Plant size of where it comes from vs where it goes matter? Does the type of biological or solids digestion of the receiving plant matter?

Any insight is much appreciated

Hello, I wanted to ask if anyone has also jumped from an operator to plant manager and what resources did you use and could share? I’m going from a 2MGD facility to a 8MGD and this will be my first managerial position in wastewater, so I am in need of some guidance and material to review and utilize. Thank you.

Edit: This is in FL and the manager is responsible for operator scheduling and duties assignments, maintaining compliance, project management, budgeting, and capital improvement. 

Hey guys! I've been browsing this sub a bunch lately and reading as much as I can about wastewater treatment. I "operate" a small wastewater treatment plant at our factory, all our system does is neutralize the pH and sends it to the RIBs, no other treatments, maybe 80k gallons a day, most of it is cooling tower blowdowns, RO concentrate, and cleaning chemicals.

I was browsing through some permits we have, I saw that our permit requires a "formally trained wastewater treatment operator" to be onsite. Nobody at our factory has ever received any formal training, they did not know this was a requirement.

So my question, what formal training can I get that would better prepare me to handle this system? I'm mildly experienced in almost all technical areas of the plant, but it seems very strange to me that all we have to do is neutralize the pH before sending it to the RIBs, either I'm missing something or we aren't doing things right.

So when we run the press we do not send the water back to the head of the plant. It goes to an aerated holding tank. We trickle it back to the head of the plant days later. It's a small package plant. I believe the polymer has a charge & through time will lose the charge in the tank being aerated.

Is there a certain amount of time in the aeration holding tank that we can be sure the polymer has lost its charge?

Thanks!

…Every fookin time!

Stuck on a question for my certification. It’s asking what is the highest temperature the effluent could be before causing harm to the outside water source. Any help would be greatly appreciated!!

I’ve got leather boots that keep getting soaked with raw influent at a food production facility. They smell like vomit, and I can’t seem to shake the smell since it’s ingrained into the leather, any ideas? I’ve actually washed these before in the washing machine but I don’t think they’ll hold up to this continuously.

Hey going in to test for my 1s soon. Anyone have any material that may be helpful for the ABC exam? Any tips would be very much appreciated too.
