Reverse Osmosis (RO) for ANSI/AAMI ST108

Water problems can stop sterile processing. 
Minerals and other contaminants can cause spots, scale, and failed results. 

Reverse Osmosis (RO) is a key step for ST108 Critical Water

RO helps remove dissolved salts and other contaminants so your water can meet tight ST108 targets. 

What RO Does

Reverse Osmosis is a membrane system. It uses pressure to push water through a special filter. 

Dissolved Salts

Organic Molecules

Larger Particles

Is RO required for ST108?

ST108 focuses on water quality results, not one exact machine. But here’s the practical truth: If your process needs Critical Water, RO is one of the most common and effective ways to reach the high purity levels many facilities need.

Common signs you need RO

RO is a strong fit when you have: 

How it Works

Spots or Film After Rinsing

We evaluate your rinse water quality to identify what’s causing spotting, residue, or film. This helps determine whether minerals, contaminants, or system issues are affecting final-rinse performance.

We assess hardness, alkalinity, and other scaling factors to pinpoint the source of buildup. This allows us to recommend the right treatment steps to protect equipment and maintain reliable cleaning results.

We review your incoming water supply to understand which minerals are driving quality problems. From there, we determine the treatment level needed to stabilize your system and meet performance targets.

We analyze fluctuations in water quality and identify the conditions causing inconsistency. Our findings help you regain control through proper testing, monitoring, and appropriately sized treatment solutions.
