Mixer logs measured 140 square inch surface area:188.4 in. sq. (test log) = 24.4 mg/L for the 706b polymer log 140 in. sq. (mixer log) = 18.1 mg/L for the 706b polymer log
8 logs/mixer = 145.1 mg/L dosage 188.4 in. sq. (test log) = 12.2 mg/L for the 703d polymer log 140 in. sq. (mixer log) = 9.07 mg/L for the 703d polymer log
8 logs/mixer = 72.5 mg/L dosage
Total dosage for the system is 217.6 mg/L
