    Man, I've never taken math and been wrecking my brain what to study for the math part that I was overwhelmed with so much info that didn't even have the desire at all to study. Thank God I found his channel. A blessing, for sure. Is this really all the math for grade one?

    Thanks for the video. I have an OIT in northern california but have been out of traditional school for about two decades, lol. Have done math refreshers for various job related tests but not a natural math wiz so always great when someone simplifies it like this.
    Gonna check out the other videos! Thanks again!!

      Stick to the basics of the book; what things are and what they do. This book is a wealth of information but is waaaay overkill if you try and retain all of the knowledge.
      I'd highly recommend seeking out a specific review course geared towards the level of test you are taking.

    This is wastewater math for the California state exams. I can't guarantee that this math will be on another states exam because I haven't taken an exam from another state. Also different states do the tests different ways. Ca goes grades 1-5 where as other states go grades 4-1 or D-A etc. Every state is different, this is ca grade 1 wastewater math. I hope that answers your question.

      OIT exams usually don't have a ton of specific wastewater info on them. OIT is an entry level position, they dont typically think you'll be able to do a whole lot of wastewater related problems.

    I have a question in a math book I need help whit. which would discharge more pounds per day of BOD to a treatment facility, a city with a population of 25,430 people, or an industry that discharges BOD at a concentration of 750 mg/I at a flow of 125,500 gallons per day? Determine the lbs.day discharged by both. The answer for industry is 785.0 lbs/day.But how do I get the answer for the city lbs/day?

  • @CAwastewater
    @CAwastewater  13 років тому

    @lerngthngs It depends greatly on where you live and who you work for. I looked up Orange County Sanitation District (which is near San Diego) and they start their OIT's (training position) at $25.42 - $30.90 per hour. Once you become a certified operator the pay increases to $30.98 - $37.66 per hour. When I was a Grade 2 in Atwater (central valley) I was making $23 per hour. Now I work in the Bay Area and I make $39.19 per hour as a Grade 3!!!!

    Chlorine is added to waste water at a constant rate of 100 pounds in 24 hours. The waste water flow averages 1.4 MGD. How much chlorine would be used in 6 hours? .............How would you use the davidson pie to this question????

    @CAwastewater  12 років тому

    This is a toughy cause they need you to know an unknown number. That unknown number is 0.17. It is estimated that every person produces around 0.17 lbs of BOD per day. So if you multiply 0.17 by the population you will get the answer.

    This question is a little confusing. If you do 100 pounds in 24 hours, then you would do 25 lbs in 6 hours (100 / 24 hours per day = 4.17 x 6 hours = 25). Are you sure you wrote the question right? email me at cawastewater@yahoo.com
