HOW TO INTERPRET YOUR JAR TEST RESULTS - Page 3

If, on the other hand, you did the pH adjustment with one of our suggested test chemicals, you may have added enough milliliters of test solution that you’ll need to add that volume to the 1,000 ml of the water sample to get a "treated" water sample volume. If, for example, you used 10 ml of a 5 % baking soda solution, your PPM ratio would be:

10 ml	=	PPM
1,010 ml	=	1,000,000

PPM	=	10 x 1,000,000	=	9,901
		1,010

These formulas would work if you used 10 ml of 5 % baking soda, or the same amount of 5 % white vinegar, to effect your pH change. In essence, for every 1,000,000 gallons of water to treat, you would need 9,901 gallons of these 5 % solutions to make the same pH change. If you plan to treat your water with a chemical stronger than one of our test solutions, we have created a RELATIVE pH SOLUTION STRENGTH table (TABLE 2) to provide a Conversion Factor (CF) for your pump sizing. Use the same formula given above for sizing a chlorine pump, substituting the 5 % baking soda concentration for the chlorine concentration, and the CF from TABLE 2 for the chlorine CF. For this example, if you choose to actually pump soda ash rather than baking soda, the CF would be 0.50.

GPD	=	10	x	60	x	24	x	9,901	x	1	x	0.50	=	14.26
								1,000,000		5

Use the pump sizing information above to select a pump for your application.

Jar tests capture a few "frozen" moments in time as far as your ongoing water stream is concerned. The tests give you a starting point from which to select a pump and treatment system. Conditions vary. Things change. Fine tuning adjustments can be made in both pump output and chemical concentration to match the conditions called for by your application.
