Boiler Make-Up Water Reverse Osmosis System

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.

Example of Typical Cost Savings
I. System Steam Pressure : 30 psig Make-up Water-side Flow rate: 15.1gpm Water side flow rate based on 80 oF temperature change from 60 oF to 140 oF. Based on continuous system operation of 8400 hr./yr., approximate energy savings are 5100 Million Btu per year. At an estimated steam cost of $5.00 / MM Btu, potential yearly savings are $25,270.00	II. System Steam Pressure : 100 psig Make Water side Flow rate: 45.1gpm Water side flow rate based on 80 oF temperature change from 60 oF to 140 oF. Based on continuous system operation of 8400 hr./yr., approximate energy savings are 15,171 Million Btu per year. At an estimated steam cost of $5.00 / MM Btu, potential yearly savings are $75,858.00
