This slide presentation outlines a pilot scale evaluation of membrane filtration for Turlock Irrigation District's new surface water treatment facility. The membrane pilot goals included:
conduct pilot testing per U.S. Environmental Protection Agency (USEPA) Membrane
Filtration Guidance Manual; optimization test phase to allow membrane
manufacturers to determine optimum
operating parameters;
two performance evaluation tests utilizing
optimized operating parameters;
demonstrate two forty-day CIP intervals;
confirm filtrate quality during performance
evaluation testing; and,
establish design and operating parameters for
prequalification of a membrane system for
participation in full scale procurement. Pilot objectives for water quality included:
verify that membrane filtrate turbidity shall be no more than
0.08 NTU in 95% of recorded values;
verify that membrane filtrate turbidity shall be no more than
0.1 NTU in 99% of recorded values and a maximum value
of 1 NTU; and,
4-log LRV (Log Reduction Value) or 99.99 percent
filtration efficiency at or below a removal of 3 microns. Pilot objectives for operation included:
demonstrate stable and reliable performance of proposed
membranes;
90% recovery ratio;
90% permeability;
90% on line factor;
40-day CIP Interval; membrane integrity verification, direct and indirect monitoring;
no more than 2 fiber breaks;
determine both the quantity and quality of residuals generated
from the membrane products; and,
experience no breaking or cracking of the hollow fiber membrane
potting within the membrane module.
