Incorporation of Novel Anti-Biofilm Molecules into NF/RO Membranes for Biofouling Control

This paper describes research of incorporation 2-aminoimidazoles (2-A1) a anti-biofilm molecule into the NF/RO membrane matrix for fouling control. The specific objectives of this research were to: (1) determine whether a 2-AI would be amenable to incorporation into water purification membranes and maintain anti-biofilm activity once incorporated, (2) incorporate a 2-AI into the matrix of a commercial membrane, and (3) evaluate the performance of the 2-AI-membrane in comparison to a control membrane lacking 2- AI in terms of water permeability, salt rejection, and biofilm inhibition.
