This slide presentation outlines a project on innovative post treatment stabilization solutions using reverse osmosis (RO). The project goals included:
provide ability to adapt to changing raw water quality or
availability; and,
maintain post-treatment stabilization without a blend source. The project approach included:
incorporating lessons learned about
raw water quality deterioration,
material selection, and
maximize flexibility;
forward thinking reliability in design,
"Legacy Facility"; and,
applied approach to post-treatment stabilization of
the RO permeate.
Permeate properties included:
unappealing aesthetically;
poorly buffered against pH changes; and,
corrosive to infrastructure. Permeate Stabilization requirements included: addition of calcium;
addition of carbonate alkalinity; and,
pH adjustment. Post treatment stabilization
fresh water blending included:
fresh water blended as percent of permeate flow;
utilizing native calcium carbonate hardness;
ease of operations; and,
cost effective. Includes 5 references, tables, figures.
