Calculations in each example 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
When and How • The manual will be available on line. • We anticipate distribution in May of this year. • Everyone at the workshop, if we have your correct email • will be sent notice of the availability. • Other notifications will be sent from FDOT and FDEP • There will be classes to help to understand and apply the • the contents of the manual. • Also stay tuned for a companion field manual. • You can direct questions to Marty Wanielista • wanielis@mail.ucf.edu • or 407.823.4144
