Carib Brewery (CBUSA) evaluated HCR against the conventional CIP acid. HCR matched the clean at less than half the concentration and left no nitrogen or phosphorus in the effluent.
| Measure | VertKleen HCR | CIP acid (replaced) |
|---|---|---|
| pH | 1.0 | <1 |
| Sample concentration | 7% | 15% |
| Nitrogen (mg/L) | 0 | 33,300 |
| Phosphorus (mg/L) | 0 | 48,950 |
| COD (mg/L) | 0 | 0 |
Rust-removal test: on four sections of one rusted heat-exchanger plate, HCR removed the rust completely without effort while the in-use CIP acid left rust behind under more scrubbing. Source: Carib Brewery (CBUSA) lab results.
