Mass balance/chlorides/Wastewater Plant
« on: September 30, 2011, 12:58:29 PM »

I am trying to find the mass balance and/or the amount of dilution water we are using in our WWT plants (in regards to chlorides).  I have an average 12000 ppm of chloride (daily) in a slurry solution coming into a dewatering plant from there it goes into the EQ tank of WWt @ 8000 ppm and leaves the plant @ 6500 ppm. the plant processes about 160,000 gal a day.  What is the equation to figure this out, do I need more information, for the answers will I have to back engineer the equation?  Any help would be appreciated.

ppm is just parts per million - if you have a chloride concentration of 12000 ppm, that means you have 12000 grams of chloride in every 1,000,000 grams of water. With that ratio and the total amount of incoming water (160,000 gal/day) you should be able to calculate how much additional water it would take to get down to 8000ppm and then 6500 ppm.
