Velocity is an important consideration in wastewater collection and treatment systems. What is the desired velocity of flow in gravity sewers and grit channels and why? At municipal wastewater treatment plants, primary clarifiers remove what percentage of settleable solids, BOD, and total suspended solids? How is percent removal of a pollutant across a unit process […]
Hydraulic loading in a treatment pond is always given in what units? Organic loading to a treatment pond is always given in what units? Is ft²/s units of flow? There are approximately how many Mgal in a pond 1 ac in area operated at a depth of 3 ft? Why does the solution bridge “work?”
What does “VSR” stand for? If the VSR in an anaerobic digester is found equal to 56%, how does WWTT recommend it be expressed for gas problems? What makes the relationship between two or more organisms symbiotic? The presence of what gas causes the pH in a wastewater treatment pond to go up and down? […]
Wastewater Technology Trainers is a must for anyone who is an operator or looking to get into the field. Eric does a great job of breaking down the different processes and his way of teaching math is a great help. I recommend his class to anyone with or without experience. They have helped me pass exams and make themselves available when you have questions. Thanks guys for your hard work.
The system that you’ve developed for teaching Operators chemical dosing problems is pure genius. This is truly a fool proof method that every Operator has the capacity to learn and use in and out of the classroom. What makes this a truly effective system is visualization of the data, minimization of conversion errors and continuity of using units and the solution bridge to solve the problem.
Thank you for your contribution to this industry, you are truly at the top of your field, especially in your ability to understand how Operators think and present concepts in a way that allows them to get it.
I find these classes very helpful in preparing for the exam and enjoy learning about the various ways treatment plants are operated around the country. I remember when I was studying for my Grade 1 & 2 exams on my own, I struggled and felt like I was not learning anything other than memorizing facts and equations. But taking your course last year in preparation for my Grade 3 made me wish I had taken your course earlier.
I would like to thank you guys for the work you do and your level of dedication to the advancement of wastewater operators everywhere. I passed my exam April 11th and I am so glad it’s over with, lol. You gave me the tools to do the job and I made it happen, but it’s the right tools that can make all the difference. You are the only teachers I will ever use going forward and the only teachers I will recommend, hands down. You will never know how much this means to me, but I can tell you it’s the world. Thank you both so much.

You and Eric are doing a great service to the wastewater industry with your classes. Eric’s method of teaching engages students, and the RR track method of teaching the math gets around memorization and lack of algebra skills. I can’t believe I’m already taking the Grade 5 exam. I started in this industry only 5 ½ years ago. For the Grades 2, 3, and 4 exams, Eric paved the way for my success. I had to study on my own, but the tools he gave me were invaluable to pass those exams.
I haven’t received my results back from the test yet but I am confident that I passed. I felt prepared for the exam due in a large (part) to taking your class. Everything I had on the exam was covered in your class. The short cuts you showed us, like…how to determine MCRT with System, Effluent and wasting setup and how to quickly determine F to M ratio was a big time saver. I was able to complete the exam, go over all the questions with 10 minutes to spare on a 2 1/2 hr exam. Thank you very much.

Just received my results for the April Grade III wastewater exam, I am very delighted to announce that with your help I finally passed it, hooray!!!! Thanks so much Mr. Eric for having patience on our last day of our study course despite most of the class not understanding the concept of the railroad method, but I made it my mission to learn all the necessities from the book I was given from your class and after many long hours IT FINALLY MADE SENSE! Keep up the outstanding work you do for us operators, my hat goes off to you and Patti, see you guys soon in the Grade 4 class! #SomeonePinchMe…

As I walked out of class on the last day having got only one of the eight math problems correct in the practice exam, I was excited knowing I had all the tools and knowledge to pass the grade 3 exam. I am not a quick study, but everything was laid out clearly in class, so all I have to do is go home and get to work. After about a week it all started to come together, and by test time I had the math down. It was a good feeling to have the ability to work through all the math and then decide what problem I was going to X out. Now [that I] have passed my grade 3 wastewater it feels so good that my income and opportunities have just increased. So if you want to improve your life, put on your big boy pants and get down to the nearest Wastewater Technology Trainers class, do the work and change your life.
Worth its weight in gold, all courses. The Grade III exam was almost easy after taking Grade III courses with less than 4 weeks to study and no sleep the night before the exam. Thank you, Patti & Eric!
I have been in the wastewater treatment profession for over 30 years, the last 23 as a state technical assistance provider. I recently attended Eric’s Advanced Activated Sludge Process Control and Optimization class and can truly say, hands down, it was the most informative and interesting class of the many I have taken over the years. Eric is a highly energetic and engaging presenter and is obviously passionate about his work and teachings. He brings with him a vast knowledge of the subject matter and is very capable of explaining engineering principles in a manner that operators can understand. If you want to be the best operator that you can be, this is one class you should not miss.
