- Dosage
Bench scale jar testing will help determine the optimum dosage. To optimize the dosage, oxidizers present in solution must be destroyed (reduced) prior to dosing Tramfloc® 901. In full-scale installations, the dosing of Tramfloc® 901 is most efficiently accomplished with an automatic feed control system.
Dosages required to precipitate one pound of metal on a 100% active basis:
Metal Tramfloc® 901, 907, # active
Cd ²⁺ 2.5 Co ²⁺ 4.7 Cr ²⁺ 3.8 Cu ²⁺ 4.4 Fe ²⁺ 7.5 Hg ²⁺ 1.4 Ni ²⁺ 4.8 Pb ²⁺ 1.3 Zn ²⁺ 4.3 Ag ²⁺ 1.9 - Dosage

- Feeding
Adjust the solution pH to above 8.0 prior to adding Tramfloc® 901. The metal precipitation reaction is almost instantaneous. For some applications, the addition of an iron coagulant (ferrous sulfate or ferric chloride) will help the coagulation and clarification operations.
