Hydrex + Sirion RO

Energy and cost saving solutions for boiler pretreatment

Water quality has a direct impact on the concentration rate in a boiler and  therefore on water and energy consumptions. 
If you face issues with your boiler pretreatment, our solution bundling Hydrex chemical service and VWT Sirion RO will not only  improve your  boiler feedwater quality but also allow for energy,  water consumptions and CO2 footprint reduction. 

Your boiler pretreatment challenge

Efficient boiler water pretreatment is critical for your boiler performance.  A poor quality (too high level of mineral content) of the feedwater requires high volumes of chemicals to avoid  fouling, scaling, and corrosion in the boiler, steam and condensate systems. 
This will also result in increased water and energy consumption to maintain the required steam quality. If left unchecked, it will also lead to increased operating costs due to expensive maintenance or even downtime. In today's environment of price volatility and ecological pressure, you are looking for solutions that can help you reduce your total operating costs while minimizing all possible environmental impacts and securing your business continuity.

Hydrex +  standardized Reverse Osmosis energy and cost saving solution 

To meet your needs, Veolia Water Technologies has designed a  complete package  associating Hydrex chemical solutions  and SIRION™standardized one pass reverse osmosis (RO) systems. 

Sirion Advanced

This product line is designed to meet the demand for high-purity water and an energy-efficient process water production system required to operate.

Hydrex chemical solutions

  • high performance chemicals specially designed for RO and boiler systems performance 
  • services from risk assessment to on site technical support. Our experts have a quite unique expertise in both water chemistry and water treatment technologies. we know how boiler / RO water treatment works and we know how to adapt at best the chemical programs to the treatment process  and to the water quality (soft water, denim, RO water)
  • equipment including our range of Hydrex controllers. combined with Hubgrade or not, our automated monitoring devices will secure the long-term performance of your boiler pretreatment by constantly controlling and balancing water,  chemical and energy use. 

In some areas, CAPEX linked to energy savings are eligible for incentives from local authorities or energy providers. The VWT team can support your industrial sites to identify and manage the best way to get these incentives.


Your benefits

Reduced energy consumption by 3 to 5%

Water savings  
eg: Hydrex-Sirion  pretreatment on 10t/h boiler= 1m3/h of water saved = 9,000m3/y of water saved=  energy savings 

Savings on Total Cost of Operation

Reduced CO2 footprint 

Maximized boiler pretreatment system’s productive uptime

Savings on CAPEX 
solution eligible to Energy Efficiency Credit (EEC) mechanisms in some countries (up to 100%  )

Hydrex + RO Boiler pretreatment solution provides significant total cost savings to leading F&B player

The company used soft water make up on their large boiler system and were interested in reducing their chemical treatment costs. Veolia Water Technologies teams determined  that replacing the older pretreatment softener system with Hydrex + RO and new softener system would allow for multiple benefits.
