How do mixed oxidants reduce TTHM formation?

Total Trihalomethanes (TTHMs) are formed by a reaction between organic precursors and chlorine. To reduce TTHM formation, either organics and/or chlorine dosing must be reduced. Mixed oxidants have four opportunities to cause this reduction:


1.  Biofilm Removal – biofilm removal in the distribution system and storage tanks reduces organics, thus reducing TTHM reactions


2.  Reduced Dose – reduced biofouling in the pipelines ultimately reduces the oxidant demand, enabling the operator to decrease the chlorine dose, further reducing TTHM formation


3.  Microflocculation – microflocculation in pretreatment removes organics into the floc, thus reducing organic precursors for TTHM formation


4.  SDS Testing – TTHM reduction occurs in 50 percent of tests
