## Overview

 

 

 

SIRION™ Mini & Midi product lines are standardized one pass reverse osmosis (RO) systems designed to meet the demand for high-purity water and an energy-efficient process water production system required. These compact, plug-and-play units ensure a small footprint and reduced operating requirements.  
   
Skid mounted and pre-commissioned, they offer cost-effective units with minimal requirements for civil engineering and extremely short delivery and start-up times.They remove 98% of dissolved organics and over 99% of large dissolved organics, colloids, and particles from brackish water.
