## Overview

 

 

 

### When Production Continuity Meets Water Purity Excellence

The Sirion™ Advanced represents the pinnacle of compact [**industrial reverse osmosis technology**](/en/solutions/technologies/sirion "Sirion™"), engineered for small to medium-scale industries where **water treatment system** reliability is non-negotiable. Built around Veolia's proven reverse osmosis membrane technology, this **premium water treatment** solution delivers consistent [**ultra pure water**](/en/applications/ultrapure-water "Ultrapure water") production across demanding applications.  
  
From **pure water for hospital** sterilisation to [power generation](/en/core-markets/power "Power") needing **boiler feed water**, and [electronics production](/en/core-markets/electronics-and-photovoltaics "Electronics & Photovoltaics ") demanding **demineralized water production**, the Sirion™ Advanced adapts to your industry's specific requirements. [Food processing](/en/core-markets/food-beverage "Food and Beverage "), [laboratories](/en/core-markets/laboratories "Laboratories"), and [hydrogen production](/en/core-markets/hydrogen-production "Hydrogen production") facilities rely on its **sustainable water treatment** capabilities.  
  
Key benefits include plug & play installation, front-access maintenance reducing downtime, **energy efficient water** production up to 5,000 l/h, and intelligent **water monitoring** through 7" touchscreen HMI. The compact design maximizes space efficiency while the RO40 controller ensures optimal **process water treatment** performance with up to 99% desalination rates.
