This slide presentation outlines a topics concerning whether low pressure reverse osmosis (LPRO) and nanofiltration (NF) membranes are considered "commodity items". The Basis of Topic includes these points:
LPRO and NF membranes commonly viewed by
owners and consultants as "commodity items";
most LPRO and NF membranes now procured via
straight capital cost bid;
evaluated bids more common in the past (1980s);
can be significant operational parameters
(feedwater pressure and acid use) differences
between and within the various manufacturers;
should industry be looking at evaluated bids
again?
The General Basis of Analysis includes these topics:
three raw water qualities assumed -
Florida Moderately Hard Groundwater,
Ohio Very Hard Groundwater,
Florida Moderately Brackish Groundwater;
three suppliers of membranes to municipal
market; manufacturer-specific membrane
performance projection software;
apples to apples as much as possible;
typical design criteria for each
application;
on per 1.0 mgd basis; and,
only feedwater pressure and acid
considered. Topics covered include: Descriptions of Raw Water Sources;
Cost Development;
Present Worth Analysis; and,
Membrane Price Differentials. Includes tables.
