Key Steps for Technology Selection
Do Not Prematurely Conclude a Specific Technology Will Provide a Solution
Detailed Assessment is Required to Determine the Best Fit Solution
Plant Operating Philosophy Typically Requires Changes to Ensure Overall Success
Perform Detailed Influent Assessment
Characterize All Sources
Equipment Drains
Floor Drains
Miscellaneous Sources (Lab Drains, Resin Transfer Water, Various Storage Tanks)
Consider Condensate System Inputs (BWR)
Do Not Rely on a Single “Snapshot”
Include Outage and Non-Outage Chemistry
Also Consider Evolutions Such as Condensate System Backwashes and URC’s
Understand the Total Costs
Confirmatory Testing
Plant Modifications
Equipment Installation
Equipment
Operations
Maintenance
Process Waste Disposition
Training
When Comparing Costs to Existing Processes Ensure All Costs are Considered
Understand There is Not a Single Generic Solution
The Proposed Technology Must Consider Influent Chemistry and Plant Goals
System Components Must be Configured Based on Specific Plant Conditions
Consider Testing With Scaled Down Equipment to Verify Performance
Another Way to Mitigate Risk
Post Implementation Keys to Success
Continually Track, Trend and Analyze Performance Data
Use Data to Define Improvements and Optimize System Performance
Maximize Filter Run Times, Media Throughput, Membrane Life
Measure Effectiveness of Changes to Any Plant Operating Philosophies
History of Membrane Technology
