Alfa Laval Alfa P-Neutra alkaline neutraliser for P-Scale procedure
- Application: P-Scale acid neutralisation after CIP cleaning
- Form: powder (added to used P-Scale solution)
- Target pH: 6-8 (safe for sewer discharge)
- Used with: Alfa P-Scale only (SKU 3284000602)
Where P-Neutra is used
After Alfa P-Scale CIP cleaning, the spent acidic solution cannot be discharged to sewer directly — the pH is too low (2-4) and it contains dissolved calcium and inhibitor residues. P-Neutra is added gradually to the used P-Scale solution while circulating through the exchanger until pH reaches 6-8. During the reaction, insoluble salts form and are readily flushed with water. This two-stage process ensures safe disposal and a fully cleaned exchanger.

Frequently asked questions
Can P-Neutra be used as a standalone cleaner?
No. P-Neutra is only a neutralising agent. For inorganic scale (calcium carbonate), an acid cleaner (P-Scale) is required. For organic fouling — Alfa Laval offers a separate Alfa Descaler / Alfa Clean range.
How much P-Neutra is required?
Depends on P-Scale quantity used and final pH measurement. Typical ratio — ~1:1 by mass with P-Scale, but exact quantity is set dynamically by measuring pH.
PPE required?
The alkaline powder is skin and eye irritant. Goggles, gloves, and lab coat are required. In poorly ventilated area, may irritate respiratory tract.
How to measure pH?
Universal litmus strips (see Amegata SKU PND50-975-84 — pH 0-12 strips) or a digital pH meter. Recommended measurement every 15 min during the procedure.
Can the solution be reused?
No. The neutralised solution must be disposed of (sewer). A new CIP procedure requires a fresh P-Scale + P-Neutra pair.
