Abstract Details

2014, Master of Science, University of Toledo, Civil Engineering.
Transparent Exopolymer Particles (TEP) are a group of molecules that have recently come under intense study and inspection in modern membrane research for their role in initiating biofilms and contributors of biofilm growth. These molecules can be formed either abiotic factors or directly from biotic sources such as bacteria and algae. In this paper, the role of TEP from direct sources (Chaetoceros Affinis, CCMP 159) have been investigated in 21% cellulose acetate (unmodified membrane) and cellulose acetate membrane modified with metal chelating ligands charged with biocidal metal copper ions. Furthermore the performance of each membrane after filtration funs and back washing cleaning operation has been compared and evaluated. The modified membrane showed less flux decline on average for the same volume permeate than for unmodified membrane, but flux recovery was the same for both. No peaks related to polysaccharides was observed in FTIR data obtained from for both membrane.
