Impact of water quality and operational factors on microcystin removal by powdered activated carbon.

ABSTRACT: The feasibility of using a 2^6-1 fractional factorial design to screen the relative importance of six water quality and operational factors in the removal of microcystin-LR (MC-LR) by powdered activated carbon (PAC) was evaluated through jar testing. The factors were: PAC type, PAC dose, total organic carbon (TOC) concentration, turbidity, alum dose, and timing of PAC versus coagulant application. Follow-up tests were performed to examine the interaction of PAC dose and TOC concentrations. All MC-LR analyses were performed by enzyme linked immunosorbent assay (ELISA) and liquid chromatography coupled with tandem mass spectrometry (LC/MS/MS). The top three effect magnitudes were the same by ELISA and LC/MS/MS:PAC dose > PAC type > PAC application time. Correlation coefficients bet
