I'm taking my Wastewater Operator Trainee Written Exam in a couple days, and these videos are extremely helpful and give me confidence on taking it! The videos are also easy to understand and you do a great job explaining the answers!

[@worldofwastewater]

Best of luck to you! I appreciate the kind words. Hopefully you passed your exam! :)

I take my test next week (just a Nevada waste water grade 1), I’ve watched all the videos. Got like 95% right. Missed a few about polymer and the seeded bod questions and what not. I can assure you I’ve learned more from KZbin videos/on the job training, then I have the Ken Kerri waste water books haha. For me I’m more of a hands on/visual learner. The ken kerri books are just such dry reading for myself. Awesome job man. These videos kick ass.

[@worldofwastewater]

Wow, what a comparison! That is a huge compliment, thank you! 🙏 The Sacramento textbooks (Ken Kerri) are great. I use them as a reference but I agree with you, it can be tough trying to learn from them. I make these videos for people like you. My main focus is to make wastewater content that is easily digestible and straight to the point for operators wanting to learn more. Good luck on your exam, let me know if you pass. Always interested in what kind of questions people are seeing on their exam so I can better tailor future content.

[@taylorburns5677]

Very good information backing the answers! The visual graphics are also pretty rad! Great video, sir! 10/10

[@worldofwastewater]

Your words are much appreciated! The most important and time consuming part of creating one of these videos is making sure I give an explanation that is clear and adequate to the question being asked. Many times these questions/answers could be videos in of themselves (might be in the future). Again, thank you and glad you’re finding them helpful! Goodluck!

[@JAZZY123413]

I’m new to the world of wastewater and boy I tell you it is too exciting learning new stuff. With that said with my book in hand accompanied by your site I just found I’m certain I will walk into the testing site with enough to take a bite out of crime. Thanks a lot God Bless!!

[@xcaluhbration]

I don’t like my current job… These videos are gonna help get me where I want to be which is in wastewater. Thanks G 👌🏾

You’re welcome! Wastewater is a hidden gem of an industry. You’re making a great choice! Lots of opportunities out there.

[@meaghansage5182]

I just want to thank you! I passed my test! This was extremely helpful!🎉🎉

CONGRATS!!! That is awesome and you should be proud of the accomplishment! Thank you for letting me know, this is my absolute favorite thing to hear! :)

[@Damien-s2w]

Preparing for 3A in NY. I'm terrified, haven't even gotten my classes in and all I hear is they don't properly prep you anyway. Thanks for putting these up to at least help me know what I need to understand better before going in.

[@LadywatchingByrd]

This exciting. I have a biology degree I've been thinking about trying to get a water plant job.. and I answered a bunch of these correctly without even knowing what the job was really. 😃👏👏

[@worldofwastewater]

Go for it! Thanks for watching and goodluck friend!

[@reohoots]

Just started in wastewater. This is the current information on the class D test? Great format and great videos. I’m gonna watch them all!!

[@worldofwastewater]

Thank you! Glad you appreciate the format and for finding these videos helpful. Comments like this really keep my enthusiasm going. To answer your question, this test isn't specific to any state or class of exam. These questions are meant to cover a wide range of topics that you should be aware of and know for any wastewater exam. There is no way of knowing exactly what will be on any exam for any specific state but no matter where you take your exam, these concepts will be there to some extent. Of course not all these questions will be on your exam, but I can guarantee some will look similar. Some questions may be more difficult than ones that are on your exam, which is great. If you can answer difficult questions, simpler questions should be easy. Goodluck!

[@chasemorris5334]

Thanks for these videos, best I've found so far. Preparing for class 3 in Ohio. Working at a small class 3 facility with extended aeration and just aerobic digestion the explanations of different treatment units and how they operate really helps. Also the math formulas you refer to are those from the ABC test/3rd part? In Ohio ABC test are different then the Ohio EPA writen test, which they quit providing so only option is ABC now. Thanks again hope to see more.

[@worldofwastewater]

Extended aeration and aerobic digestion, sounds like a pretty neat plant. It's so important to have well rounded knowledge when it comes to these exams, which is something I think my exam does a good job of touching on. There is always more to know about all the different processes though. Your studying should go beyond my videos, but I believe this is a good guide to some of the major concepts you will see on a exam. I am from New York, so that is what the formula sheet is based off of. I just check out the Ohio one and it is VERY similar (NY seems to have more on it). All the standard formulas you would expect to see are on the Ohio ABC formula sheet as well. So it shouldn't be a problem. Thanks for watching and Goodluck!

[@chasemorris5334]

What manual do you need to study?

[@chefboyardee40]

These videos are great, do you have more coming because you left off on part 15 and on questions 70 -75. thanks

[@worldofwastewater]

Thank you so much for watching. I apologize for the delay with the next part. I promise it's being worked on.

[@bradrozell]

I would suggest indicating which exam "grade" level your content relates to.

[@worldofwastewater]

I appreciate the suggestion. This test is meant to be for everyone. This test goes over a range of topics that an operator will likely need to understand no matter what "grade" test they take or where they take it. I always say, if you end up studying harder questions than you may be required to answer on a exam it will make taking the exam much easier. Secondly, because there are differences in what "grades" can mean in each state, it's hard for me to do that (I'd have to list 50 different states). In some states a "4" license can mean the easiest test and might mean most difficult exam in others. Let me say again, I appreciate the suggestion. Goodluck on your exam and hope you find these videos helpful.

[@joshuaj6426]

Man! Thanks for all the hard work putting these videos together. Tons of help and excellent explanations for everything. Really appreciate the effort and look forwards to more videos in the future.

[@worldofwastewater]

Thank you! Kind words like yours really keep my enthusiasm for this channel alive. I look forward to delivering more videos. Glad you find them helpful!

[@N6J6R6]

I just found your channel and am going to dive into the videos. I'm in Denver Colorado testing for my C license. Which videos/practice tests are geared towards that level? Please let me know. Thank you doing these videos and practice exams.

[@worldofwastewater]

You will absolutely find these concepts and/or some similar questions. Many people have told me that these questions helped them pass their exam from all over the USA. However, these videos should not be the only thing you study but will definitely give you an idea of what to expect and what to dive deeper on. Thanks for watching and goodluck!

[@blaketurney8641]

Keep it up my friend

[@worldofwastewater]

Thank you for the motivation!

[@freddiegarcia2265]

All these questions come in the florida wastewater operator c test?

[@worldofwastewater]

These questions can be found on any wastewater exam, they go over concepts that every operator should become familiar with. I know for a fact that these questions have helped many people prepare and pass their exam. This is not a copy of any specific test. Thanks for watching and good luck!

[@bissyblue7]

These are great; but what level are they focused on? I'm writing my class 2 in Ontario next month and I don't find the textbooks suggested by OWWCO very useful

[@worldofwastewater]

These videos are great for any level, however they lean to the more advance levels for most exams I would say. But if you learn these, the lower level exams should be easier. I have used the WEF and Sacramento State textbooks a little while studying. Honestly finding practice tests online and completing as many multiple choice questions as you can is the best way to prepare for the exam (in my honest opinion). Read up on the stuff you are less familiar with or don’t have at your plant. For example my plant didn’t have a digester, so I studied PowerPoints that I found online that explained them. Goodluck and thanks for watching! :)

[@abin5699]

Great information!

[@worldofwastewater]

Thank you! =)

[@tomorowsnobodys]

Could you add the formulas and conversion factors and all that good stuff to the exam document?

[@worldofwastewater]

I do do that because it wouldn't be helpful for actually practicing for the real exam. You are given a sheet with formulas and conversions when taking a wastewater exam in America (and I'm fairly certain in all of Canada and probably the rest of the world). With that said, I encourage you to use the formula and conversion packet that will be given to you when taking the test in your state. This can usually be found online where you sign up to take an exam, or ask a fellow operator colleague. Thanks for watching!

[@ericlawrence9060]

I got 100% lol. Question 3, wrong... your blanks can be 0. Also, when i run the plant 0 can happen :).

[@worldofwastewater]

Having zero BOD in the effluent is something to be proud of, nice job! I wouldn't call question 3 wrong, as it is in regards to the testing of BOD in actual samples whereas the blanks are part of the QA/QC measures that are in place to prove reliable and accurate testing. Nonetheless, you do bring up a good point that should be known. Which is, BOD blanks should not have a depletion greater than 0.2 mg/L, which would indicate no contamination of the dilution water. Thanks for sharing. =)

Hi! Will this help me pass my grade I in Wastewater here in CA?

[@matthewthompson4837]

These questions go over general and fundamental concepts of wastewater and you will most definitely run into some of these questions, or similar ones no matter what state you take an exam in. You can find a link to the test in the video description. Thanks for watching!

[@SilenceMakuwa]

​@@worldofwastewaterhie where can I study about wastewater here in South Africa, besides online Alison is there any ather platform

[@williampalmer7447]

I really don't see the difference between question #2 answers A or C, other than C is more generalized. Even in your explanation, you say "solids that settle on the bottom of the clarifier...".

[@worldofwastewater]

I understand where you are coming from and to a certain extent choice A is sorta correct but it isn't the best choice. I will admit I would probably change that choice so the answer is more clearer if I could go back. With that said a sludge blanket isn't specific to only primary clarifiers. The question is asking what is a sludge blanket in general. Choice A is an example of a sludge blanket, but not the definition of one. Great question, thanks for watching!

[@EvanCurry-d8o]

Is there videos for questions 86-100?

[@majidazeem670]

Hello I am working as process Engineer in sewage treatment plan at Dubai. What certification or license will I need to be able to work in Canada and USA ? Can I get that certification online?

[@worldofwastewater]

Hi, this is a difficult question to answer. In the USA it will depend on what state you are in. If you are looking to be an engineer, you probably wont need a wastewater operator license. However if you are looking to get your wastewater certification you will need to take several wastewater courses (depends what state you are in). Usually there are online versions of some of the courses. You will also need to have time worked at a treatment plant as an operator trainee. Hope this helps and goodluck.

To anyone who has taken the test before, what should we expect?

[@worldofwastewater]

You should expect to see some of the questions I go over in this series. :) I cant speak for every test and every test question there is but most exams follow the same categories state to state. The biggest difference is that there can be questions regarding specific state regulations for the state you're taking the exam in. Goodluck!

[@SpearoChris]

Can number 2 also be (A)?

[@worldofwastewater]

Even though choice-A describes a sludge blanket, sludge blankets are not specific to primary clarifiers, which is why choice-C is the better answer. Thanks for watching and good question!

What states have easy questions like this ? Floridas lowest C test is a thousand times harder

[@worldofwastewater]

Not all questions in this series are this “easy”. This series of videos goes over a range of material. It is loosely based on New York 3A exams (2nd most difficult in NY state). I have had quite a few people from various states let me know that what I cover was extremely beneficial in helping them pass their exam. I of course can’t go over every single question that someone might find on their exam but I hope that people will dive deeper into these subjects and understand the different types of questions they may expect to see when taking their exam. I hope you continue to find these questions easy because that means you will do great on your exam. I’m always interested to hear what kind of questions people run into on their exams, it provides me with better material for future videos. Goodluck and thanks for watching. :)
