Real Specifications
| Spec | Value | Source document |
|---|---|---|
| CIP foulant-to-cleaner reference table | Inorganic scales: acid cleaners (citric acid, hydrochloric acid); Organic fouling: alkaline cleaners (sodium hydroxide); Biological fouling: specialized biocides/sanitizers; Colloidal fouling: surfactant-based cleaners | AXEON Water Technologies — Reverse Osmosis / Membrane Systems |
| CIP-Series construction | Corrosion-resistant stainless steel frame, integrated heating element for cleaning-solution temperature control, level switches to prevent dry-running the pump | AXEON Water Technologies — Reverse Osmosis / Membrane Systems |
| Cleaning trigger thresholds | Normalized permeate flow decrease of 10-15%, normalized salt passage increase of 10-15%, or pressure drop increase of 15-20% across membrane elements | AXEON Water Technologies — Reverse Osmosis / Membrane Systems |
CIP-Series skids include level switches specifically to prevent dry-running the cleaning-solution pump — a real failure mode on mobile CIP equipment run unattended.
A 10-15% drop in permeate flow or a 15-20% rise in pressure drop across the membrane elements is the trigger for cleaning, not a symptom to wait out. Reaching for citric or hydrochloric acid against inorganic scale only works if the foulant is correctly identified first — running the wrong cleaner class treats the wrong problem and wastes both chemical and a cleaning cycle.
Every material and product claim on this page traces to real, vendor-published documentation on file with LibertyCES. Chemical compatibility depends on exact concentration, temperature, and duty cycle — confirm current specifications with the manufacturer and request a spec review before final specification.
