Stop Discarding Acid That Works

PRO-pHx:
Acid Bath Life Extender for Metal Finishing Operations

How PRO-pHx Works

In metal finishing and electroplating operations, acid baths degrade over time, not because the acid loses its strength, but because dissolved metals accumulate and interfere with bath performance. PRO-pHx is an acid bath life extender that addresses this specific failure mode, allowing facilities to continue using acid that would otherwise be discarded.

At a 1% concentration, PRO-pHx acts as a metal-management catalyst within the acid solution. It interacts with dissolved metal ions (iron, zinc, chromium, and others) reducing their negative impact on bath stability and performance. The result is an acid bath that stays usable significantly longer without any change to your existing process or chemistry.

Unlike filtration systems or metal recovery equipment, PRO-pHx requires minimal capital investment and no production downtime to implement. It works within your existing acid bath maintenance routine and is compatible with most common mineral acids including hydrochloric, sulfuric, nitric, and phosphoric, as well as their common blends.

Facilities using PRO-pHx as part of their electroplating acid bath maintenance program have reported 60–90% reductions in new acid makeup costs and significant decreases in hazardous waste disposal volume — reducing acid disposal costs without changing what works in their operation.

Most acid baths are dumped too early...

In most metal finishing operations, acid is discarded not because it has lost its reactivity but because dissolved metals have built up to the point where the bath becomes unworkable. The acid is still chemically active. It's the metal loading that forces the dump.

For electroplating and metal finishing operations, that means higher acid replacement costs, more frequent hazardous waste disposal runs, and production downtime you didn't need to schedule. Reducing acid disposal costs and extending acid bath life are priorities for any facility running high-volume acid systems, but most don't have a practical way to do it without equipment changes or process disruption. PRO-pHx is designed specifically for that gap.
