Boiler Make-up Reverse Osmosis Systems

The Model BMURO, Boiler Make-up Water Reverse Osmosis System is a fully integrated system which is designed and manufactured to remove up to 99% of the contaminants and impurities (alkalinity & conductivity) from the boiler make-up water prior to the make-up water blending with condensate return. By physical treatment of the make-up water to reverse osmosis (RO) quality, fuel costs and boiler operating costs are significantly reduced by the reduction of boiler blowdown rate. Reduction in energy consumption is normally expected to be the most significant savings; however, boiler chemical treatment cost reduction can in some cases be as high as fuel savings. Each BMURO system is custom designed and manufactured to meet specific site requirements. All controls are fully integrated into the system via UL-Listed, single-point power connection Industrial Control. All systems are fabricated and welded per ASME Section IX Code and Standards, and are hydrostatically tested prior to shipment.
