Plant and Your People
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? […]
Corwin Mossman – Online Grades IV/V Student
Because of your help, I felt that the wastewater grades 1,2,3, and 5 (I skipped the 4) exams were almost easy. I passed them all on the first try. The math method you teach is incredible. I also I passed my Water Treatment grade 3 exam last week and I didn’t even have to look at the formula sheet to do the math. Your method really works. You guys have an amazing program going on and I really appreciate all your hard work. – Corwin Mossman, Water Treatment Plant Operator II, Lake Arrowhead CSD
Joe Velasquez – Online Grade III Student
I want to thank you (Eric) and Patti for the work that you two do. Your program is truly a benefit to wastewater operators. I never used the solution bridge before, but I knew about it and was a little skeptical. After taking your class and putting in A LOT of practice time, I got it. Your class really made the test a whole lot easier and less intimidating. Thank you again! I won’t ever take a test again without the solution bridge! – Joseph Velasquez, Journeyman Maintenance & Facilities Worker for the City of Buellton
Kevin Avalos – Online Grade III Student
I have passed my grade 3 exam! Woot woot! I just want to thank both you and Eric (The Wahlbergs) and WWTT for helping me achieve this goal. Specifically, I’d like to thank Eric in his approach to teaching wastewater math, principles and concepts. Not only is the examination material covered really well, but being that there is still so much to learn about wastewater, I really appreciate the thoroughness of how each topic is broken down and explained. – Kevin Avalos, Grade III Operator, Dublin San Ramon Services District
Thank you for such a wonderful week of growth and development. You and Eric have provided me with a wealth of knowledge and the tools I need not only to ace the upcoming grade III exam, but to help me gain a clearer understanding (hopefully “crystal” in time!) of the wastewater world and all of its components.
From voicemail message: “This is Marco, and I didn’t pass my April exam, but I just passed my October exam. What happened was I had went over all my notes, even comments Eric had made in my Grade II Handout, and I studied I studied I studied, like my eyes were bleeding, and I ended up passing. I just wanted to tell you guys thank you, keep doing what you’re doing, it really works. The aha moment popped up in my head, and tell Eric I said, ‘Wastewater math is AWESOME!’ I love you guys. Thank you thank you thank you so much for your dedication, and for believing in me even when I didn’t.”
I failed the Grade II after taking a Grade II class with another trainer and then I tried an online class, but I still didn’t pass. My boss said if I didn’t pass the next one, I’d find myself in the soup line. Fellow operators recommended WWTT, so I signed up for the Grade II and then I put my nose to the grindstone. Eric teaches with a passion and excitement and keeps students up front and paying attention. That’s what makes all the difference, and makes this training stand out from other trainers. When I took the exam that third time, the answers just came flying out of my pencil. I felt so confident when I walked out, because I knew I had aced it.
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.
