Analysis of Odors from Flocculant Polymers
Flocculant polymers vary in their chemical structure and some of the structures may be more degradable than others. Chang et al. (2001) have suggested some degradation pathways may lead to the generation of odors, specifically from the production of trimethylamine (TMA). This hypothesis was tested by incubating polymer samples at high pH and in other chemical environments then using solid phase microextraction (SPME) coupled with GC-MS to analyze head gases for TMA. It was found that at least one type of polymer is prone to TMA release at high pH, indicating that this type of polymer should not be used when biosolids are to be lime stabilized.
