Dosage

Your water treatment representative will make dosage recommendations depending upon your application.; To determine the approximate dosage of Tramfloc® 903, use the following formula :; mls Tramfloc® 903 = (total ppm metal) x (no. of gallons) x (Y); The factor (Y) in the above formula is determined by the atomic weight of heavy metals. In a wastewater stream containing several mixed metals, the average atomic weight of the metals is used to arrive at the number 0.0401. When calculating dosages for individual metals, (Y) is as follows :; When Tramfloc® 903 is used as a polishing agent, consider only those metals remaining in solution after hydroxide precipitation (via pH adjustment) for calculating the dosage per the above formula. Bench scale jar testing should be performed to determine the optimum dosage, preferably monitored by an ORP electrode. To optimize the dosage of Tramfloc® 903 required, oxidizers present in solution must be destroyed (oxidized) prior to dosing Tramfloc® 903. The type and concentration of chelators, coagulants, and other components of the wastewater may also effect the dosing criteria. In a full scale installation, dosing of Tramfloc® 903 is most efficiently accomplished with an automatic control system which includes an ORP electrode, millivolt controller and metering pump.

Toxicity Comparison

The following table compares the toxicity levels of Tramfloc 903 to dimethyldithiocarbamate (DTC), commonly used as a precipitant. DTC is also an effective industrial microbiocide - particularly as copper carbamate, the compound formed when precipitating copper with DTC. Note that the toxicity levels of DTC are much higher than those of Tramfloc® 903.
