    SWG output, how's my math

    According to Hayward my SWG can produce a maximum of 1.4 lbs of chlorine/day. So I did the math.....I think is correct.
    1.4 lbs =22.4 oz a day(24 hours)
    That's 0.933 oz per hour.
    I run my pump at the moment for 10 hours a day at 1200 RPM (100 watts of power) turn over rate approx 3 times......yes I know that's probably over kill, but anyway. My output is set at 50%. Which means that the system will generate chlorine for 5 of the 10 hours.
    That comes to 5 x 0.933 = 4.66 oz of chlorine. I f I plug that number into pool math I get 5 PPM of FC during my run time. My system seems to be maintaining ok. This gives me nice bench mark.

    FC at 430PM hottest part of day =4.5ppm
    TA = 125
    PH = 7.4
    CYA = 55 in progress of raising to 70
    Salt = 3500
    Water temp = 90F
    CH = 250

    Re: SWG output, how's my math

    Your signature says a T-3 cell, but it is the T-15 that produces 1.4 lbs per day.

    Your math is right, but I think you started with the wrong output. The T-3 is only 0.6 lbs per day ... which puts your daily addition at 2.1ppm FC each day which is more reasonable.

    Re: SWG output, how's my math

    Is there a relationship between flow rate and chlorine generation? That is, does the cell generate the same amount of chlorine at a pump speed of 1200 rpm as it would on the same system at, say, 1600 rpm?
    Thanks,
    Mike

    No relationship. The SWG either has enough flow to generate or it does not and will not generate. The amount of FC produced is independent of the pump speed.

    Aw...yes you are right.......my cell is a T-3. Thanks for pointing that out. I need to re-do my math.

    Thanks for doing the math. I was wondering how to do the same thing and saw your post. Confirmed I was on the right track with my math

    Another thank you!
    I now understand how that works and was able to do the math for what my SWG generator produces. You might have helped me solve my problem.

    Re: SWG output, how's my math

    Thanks . I hope this helps someone other than me. I was looking at setting a bench mark or reference for doing any additional adjustments. I know testing is still required but this shpuld keep me in the ballpark
