Ok if you want smaller particles then just limit the current and you should be able to get your 80 ppm however it will take a lot longer... To hold the current to say 10 ma (milliamperes) or less just us the formula R=V/I (ohms law) where resistance R is in ohms, voltage V is in volts and current I is in amps (milliamperes is thousandths of an amp). So for 3 9V batteries (3x9=27V) we have R= 27,000 ohms or 27k (27/0.001). The colour bands on the resister will be red (2), violet (7),orange (000), gold/silver (5/10% tolerance) 1/4 or 1/2 watt rating will be fine.
