Description
The aerospace industry requires ultrapure RO/DI water for the high-precision fabrication of aircraft components. Ampac USA's uncompromising approach to manufacturing and performance ensures that every RO/DI system consistently produces true ultrapure water at 18 megaohms of resistivity, even after years of operation. This consistency can be difficult to achieve if the components and build quality of an RO/DI system are subpar, and resistivity can fall below ultrapure requirements, unknown to end-users.
Ampac USA deploys high performance, ultrapure RO/DI systems worldwide using only the best workmanship and components. Our engineers can oversee the commissioning and installation of a system, and we can train end-users to use the purifiers without any assistance within a few days time.

Applications
Features and Benefits
What water purity level is required for aerospace component washing and anodizing processes?
Aerospace component washing and anodizing require ultrapure water at 18 megohm-cm resistivity to prevent ionic contamination on precision metal surfaces. Even trace minerals at 1-2 ppm can cause spotting, oxidation interference, or adhesion failures in anodizing baths. Our RO/DI systems deliver consistent 18 megohm-cm output with multi-stage polishing to meet those tolerances.
How does reverse osmosis protect aerospace anodizing bath chemistry?
Anodizing bath makeup water with high TDS introduces sulfate and chloride ions that compete with the anodizing reaction, producing uneven oxide layers. AMPAC USA builds RO systems that reduce incoming TDS by 95-99%, typically bringing 300-500 ppm municipal water down to under 10 ppm before the DI polishing stage. That clean feedwater extends bath life and reduces reject rates on finished components.
What flow rates do aerospace facilities typically need for ultrapure water systems?
Production washlines and multi-tank anodizing operations commonly require continuous flow between 500 GPD and 50,000 GPD depending on part volume and rinse tank turnover rates. Our systems are sized to match peak demand with buffer storage, so rinse tank TDS stays below 5 ppm throughout a full production shift. We also design recirculating DI loops that maintain resistivity without constant membrane cycling.
Can AMPAC USA systems handle the silica and hardness levels common in Western US aerospace facilities?
Many aerospace facilities in California, Arizona, and Nevada deal with feedwater silica above 20 ppm and total hardness above 300 ppm as CaCO3, both of which aggressively foul RO membranes without pretreatment. Our systems incorporate antiscalant dosing, softening, or media filtration upstream of the membrane array based on a site-specific water analysis. Proper pretreatment extends membrane life past 5 years and keeps replacement costs predictable.
What monitoring is built into aerospace ultrapure water systems?
Inline resistivity monitors at the point of use give real-time feedback on water quality, with alarms set to alert operators when resistivity drops below 15 megohm-cm. AMPAC USA also integrates TOC monitoring for applications where organic contamination is a concern, such as optical component cleaning. Data logging capability supports quality records required under AS9100 and customer traceability requirements.
How does AMPAC USA handle system validation documentation for aerospace customers?
We provide full IQ/OQ documentation packages upon request, including membrane test reports, system performance data at commissioning, and P&ID drawings. Aerospace primes and Tier 1 suppliers frequently require traceability on major system components, so we source membranes and instruments with full manufacturer certifications. Our engineering team can work directly with your quality department to meet audit requirements.
