This powerpoint presentation begins by providing a brief overview of membrane filtration. Ceramic membranes are presented, focusing on process and structure. A comparison of ceramic vs. polymeric membranes is presented, along with a case study where a pilot study on Oyster Creek water, in the state of Texas, was conducted
using polymeric membranes.
Ceramic membranes were evaluated on a
bench-scale test for the same source water.
The experimental part of the ceramic membrane
study was conducted at McMaster
University.
Background information includes the following: source water is high in organic
content (6 to 8 mg/L of TOC, 350 to
550 CPU of color) and high turbidity
(200 to 600 NTU);
experimental mode - cross flow and
dead-end filtration;
the membranes tested were 15 KD
molecular weight cut off;
the fluxes tested ranged from 75 to
120 gfd; and,
polymeric membranes fluxes tested
ranged from 30 to 70 gfd. Presentation conclusions indicate the following: more robust and efficient in performance;
no sedimentation tank and a rapid sand filter
required and therefore, a small footprint
treatment plant;
resistant to almost all oxidants and extreme
operation conditions including pressure,
temperature and chemicals; and,
high permeate flux recovery. Includes tables, figures.
